The direct fired steam generator incorporates a mixer-burn-

er with a tough, refractory lined combustion chamber which

ensures safety, efficiency and many other improvements

over current steam generating systems.

This new system drives air into the mixer-burner, combining

it with fuel where the mixture is ignited as it enters the com-

bustion chamber. Combustion is 100% completed.

Water is then sprayed into the hot gases exiting the cham-

ber, thereby creating INSTANT STEAM.

It also capitalizes on non-condensable stack gases which

represent a useful supply of energy when combined with the

steam rather than being vented, thus maximizing efficiency.

ELIMINATE YOUR BOILER AND SAVE WITH ADVANCED TECHNOLOGY

HIGH PRESSURE 8 PSIG, MAXIMUM STEAM PRESSURESTEAM GENERATORS ARE RUN AT 80% CAPACITY DURING CONTINUOUS DUTY

- 1 -

The Steam Engineering direct-fired Steam Generator

represents a breakthrough in steam generation technol-

ogy. It is highly efficient and uses up to 50% less fuel

than conventional boiler systems. Early applications of the

new technology were confined to the concrete industry

in the curing of concrete pipes, blocks and other pre c a s t

products. Currently, Steam Generators are replacing

boilers in a wide variety of applications and industries.

PRINCIPLE OF OPERATION

T h ree services are re q u i red for operation: a water supply

of 40 to 50 PSIG; a power supply (normally 460/575V,

3 phase 60 cycle); and a supply of natural gas, propane

or #2 oil. During operation, an electric motor drives a

positive displacement blower through a filtered air inlet

chamber and discharges it into a burner chamber where

it is mixed with fuel and ignited. The burner is a high effi-

ciency unit which burns virtually ALL the fuel /air mix-

ture with minimal undesirable products of combustion

being formed. Carbon monoxide output levels are

below 10 parts per million.

Water is introduced at the discharge of the combustion

chamber and sprayed through a nozzle at the hot gasses

that are swirling out of the combustion chamber. The

water is vaporized instantly and steam is emitted thro u g h

the flanged discharge pipe.

The non-condensed gases, instead of being vented

as in most fuel burning systems, are mixed with the steam

to provide a substantial additional source of energy.

In conventional steam boiler systems, the tempera-

ture of the steam in dependent on its pressure. With the

STEAM ENGINEERING Steam Generator, steam tem-

perature is controlled by modulating the amount of

water that is sprayed into the hot gases. This is accom-

plished with the use of a microprocessor based tem-

p e r a t u re controller and a downstream temperature pro b e.

The desired temperature of the steam is dial select-

able from the control panel of the unit or remotely from

an optional key pad. This type of control gives the unit

a wide temperature range from super saturated water

vapor at approximately 212ºF to a very dry steam at

approximately 350ºF. This wide temperature span is

attainable across the entire system back pressure range

of maximum 8 PSIG.

BENEFITS

An immediate benefit of the STEAM ENGINEERING

Steam Generator is that steam is available on demand.

Within 15 seconds of switching on the machine, steam

is generated. When steam is no longer required, the unit

is switched off.

The major benefit of the unit is its ENERGY SAV I N G S

features. Due to its high efficiency, it burns less fuel to

produce a BTU of output steam. Also, because of its

unique ability to produce instant steam, it only consumes

fuel when steam is required. It is not maintaining a

mass of water at a high temperature when steam is

not required.

The unit is packaged, pre-assembled and easy to

install wherever the steam is required. As pressure does

not exceed 15 PSIG, no special boiler room, no stationary

engineer or high insurance rates are required.

APPLICATIONS

The STEAM ENGINEERING unit will find application in

many industries where boilers have traditionally been

used. Current and potential applications are as follows:

✔ Kiln curing of concrete pipes, blocks and other

concrete products.

✔ Steaming of aggregate piles in winter to prevent

freezing.

✔ Sparging of liquids and slurries in pulp and mining

operations.

✔ Sterilizing growing rooms and potting soil, heating

bales of straw for mushroom industry.

✔ Reconstituting airplane de-icing fluid.

✔ Internal cleaning of transportation tank to remove

materials and speed drying.

✔ Heating of hot water for processing and personal

use.

✔ Pelletizing in feed mills.

✔ Heating and inflating plastic liners for underground

sewage lines.

✔ Heating wheat to increase production by 2%.

A number of other applications are being evaluated

as potential users understand that the unique features

of the STEAM ENGINEERING unit can help them solve

many of their processing and heating problems.

Most modern boilers will list an efficiency of about 80%

“from and at 212ºF”. This means that if water enters the

boiler at 212ºF it will require 1,212.5 BTU’s to produce

a pound of steam (970 BTU’s). Since process and

concrete curing systems use 100% make-up water

(50ºF) this water must be pre-heated or heated by the

80% efficient boiler. 162 BTU’s must be transferred

to the make-up water to raise its temperature from

50ºF to 212ºF.

• A boiler will consume 202.5 BTU’s to heat

this water.

• A boiler, thus, requires 1212.5 BTU’s plus

202.5 BTU’s for a total of 1415 BTU’s to

produce a pound of steam (970 BTU’s) –

assuming everything is ideal.

• This represents a maximum theoretical

efficiency of 68.5%.

To this must be added the losses which occur

due to intermittent firing, tube scale, impro p e r

combustion, startup and shutdown, standby

radiation, operating radiation, excessive line

radiation, blow down and steam leakage.

IT IS RARE TO FIND A BOILER CURING CONCRETE

OR IN A PROCESS SYSTEM WITH NO CONDENSATE

RETURN, OPERATING AT MORE THAN 50% EFFICIENCY.

Also, since boiler tubes are subject to corrosion, often

expensive chemical treatment of water is necessary to

reduce this corrosion or oxidation. This will vary from

minimal water softening, (which we recommend for our

systems) to chemical treatment, which can cost

$5,000.00 annually or more.

Steam Engineering is an industry leader in its field.

In addition to designing, manufacturing and servicing

its own line of Instant Steam Generators, its technical

service personnel possess knowledge, experience and

trouble shooting skills that have been developed over

years of providing service for its equipment as well as

those manufactured by others.

Steam Engineering can provide the experience and

inspection techniques necessary to assess the condition

of your equipment and identify potential problems.

These problems usually occur in the following areas:

• Flame and Combustion Equipment such as flame

safeguards, spark plugs, ignition transformers and

regulators;

• Safety Components such as water, gas, temperature ,

pressure and limit switches;

• Valves such as water and fuel valves, actuators and

solenoids;

• Electrical Components such as wiring, relays, t i m e r s ,

motors, drives, controls for temperature , heat, water,

fuel, moisture and pressure;

• Blower Components such as inlet filters, drive align-

ment and belt tensioning.

Steam Engineering can provide basic and recurrent

training for owners and operators of steam generator

systems. Each training program is customized to meet

our customer’s specific needs and consists of “hands-on”

sessions at the site. We can also provide compre h e n s i v e

commissioning and start-up service after the repairs or

refurbishing are complete. Most parts orders placed

with Steam Engineering are shipped within 24 hours to

help reduce your downtime.

Each steam generator is complete with its own CSA

approved control panel, programmed to control the

steam generator in accordance with the specific pro c e s s

requirements for which it was sold.

The panel is easy to operate, simple to understand,

no proprietary software is required and a fully detailed

ladder wiring diagram is provided for trouble shooting.

The control wires are numbered for easy reference and

trouble shooting.

If an alarm situation does occur, the relevant pilot

light is latched “on” so that the operator knows that a

situation occurred, even if the situation corrects itself

and the unit restarts before the operator is available.

All the components are field replaceable at site.

Parts are readily available from Steam Engineering

(800) 388-1339.

The following are provided on the front face of the panel:

• switches for operator interface;

• pilot lights for trouble shooting;

• a programmable steam temperature controller;

• manual, fused, 3-phase disconnect switch.

The steam temperature controller includes:

• a hi-temperature limit with automatic reset;

• a digital read-out of the steam temperature;

• steam temperature can be manually adjusted and

controlled through PID;

• shuts off fuel if temperature gets too high, allows unit

to restart when temperature lowers to normal range.

A manual start, automatic stop count-down timer is

also supplied for basic operation.

The panel includes three dry contacts for connec-

tions from an automatic control panel (in the field) so

that the steam generator will have automated operation

to cycle and hold a specific temperature in the process

area. The process area can be one or several requiring

temperature control. The automatic control panel can

also be supplied once the customer’s specific require-

ments are known. Wiring between the steam generator

panel and any field devices or the automatic control

panel is by others.

STEAM GENERATOR CONTROL PANEL

- 4 -

This control panel and valve assembly equipment is

designed to allow automatic temperature control of the

water tank and aggregate/sand pad or bins. The CSA

approved panel is available in addition to the operating

panel mounted on the Steam Generator.

The control panel is complete with a 7-day timer to

control the on/off cycle of the Steam Generator. The

timer can be programmed for Ordinary Timer Operation

(factory setting), Multiple-day Operation, Cyclic Operation,

or Pulse-output Operation. The Steam Generator panel

must be set to “Auto” before operating this separate

panel.

The valve assembly consists of a tee with two butter-

fly valves (air or electric operated) with interconnecting

linkage so that steam passes either to the water tank or

to the aggregate/sand pad or bins. Each butterfly valve

has two limit switches, one to indicate valve open and

the second to indicate valve closed.

The panel includes a selector switch

with three settings; Sand, Sand & Water,

and Wa t e r. The Sand setting allows steam

to heat the aggregate/sand pad or bins

only. The Sand and Water setting allows

steam to heat both the sand and the

water, however, the water temperature

takes precedence over the sand temper-

ature. Once the water temperature has

reached its set point, the butterfly valves

change to allow the steam to go only to

the sand bin. If the water temperature

drops below its lower set point, the

butterfly valves change position again so

that the steam is directed only to the

water tank. The Sand and Water setting

will maintain the temperature of the water

tank first and then heat the aggregate/

sand pad or bins.

To heat only the water tank, the setting

switch is turned to the Water position.

The butterfly valve will open to the water

tank and close to the aggregate/sand pad

or bin. If the Process Value Temperature

reading in the water tank is lower than

the Set Value Temperature, the Steam Generator will

start and heat the water to the Set Value Temperature.

When the water temperature reaches Set Va l u e

Temperature, the Steam Generator will go into its cool-

down mode.

In the cool-down mode, the Steam Generator will

switch to air, and the butterfly valves will turn to the dire c-

tion of the aggregate/sand so that the water temperature

does not cool down too quickly, however, the residual

warm air from the burner will continue to flow. After 25

to 30 minutes, if the temperature is still above the Set

Value, the Steam Generator will shut down and restart

only when the water temperature drops below the Pro c e s s

Value Temperature. If the temperature drops below the

Process Value while the Steam Generator is in the cool-

down mode, the steam cycle will restart and open the

butterfly valve towards the water tank and close the

valve to the aggregate/sand pad or bin.

READY MIX CONTROL PANELA G G R E G ATE, SAND AND WATER TEMPERATURE CONTROL

The Steam Generator panel must be set to “Auto”

before operating this separate panel.

The temperature in each curing kiln is sensed and

controls the opening and closing of electric or air oper-

ated steam control (shut-off) valves, one per kiln. All

field wiring, piping and valves will be supplied and

installed by others.

Upon filling a kiln, the operator closes the access

door, sets the temperature controller to the required

curing temperature and pushes the start button.

Steam is introduced into the kiln until the pre-set

curing temperature is reached, as sensed by the

thermocouple in the kiln. The steam generator cycles

off when the pre-set curing temperature is reached.

If the temperature on the kiln drops to a pre-set differ-

ential temperature, the steam generator restarts and

delivers steam until the pre-set curing temperature is

reached. The steam generator then cycles off until it is

needed again.

If more than one kiln is being cured at the same

time, this heating process is the same for each of those

kilns. If the temperature in those kilns is above its pre-

set differential temperature the steam control valves

would be closed to their respective curing kiln except

for the last one being started-up. As each kiln area

comes up to its operating set point temperature, the

thermocouple sensor closes the control valve to that

specific kiln area.

When all of the kilns are up to their curing tempera-

ture, all of the valves will be closed and the generator

will cycle off. If the curing temperature in any of the

operating kilns falls below the pre-set diff e rential

t e m p e r a t u re, the steam cycle will restart and the

applicable steam control valve will open to the kiln

requiring the steam.

This control panel and valve assembly equipment is designed to allow automatic

temperature control of multiple curing kilns. The CSA approved panel is available in

addition to the operating panel mounted on the Steam Generator.

The separate control panel complete with

• timer • thermocouple for each kiln

• selector switch • temperature controller

• butterfly type shut-off valve (air or electric operated)

• dry contacts to receive electrical input from field temperature

sensors in each of the kilns

STEAM ENGINEERING – ACOUSTIC ENCLOSURE

The natural gas Gas Booster is manufacturedby Steam Engineering and is used with steam generator systems where the incoming natural gas supply servicedoes not have adequate pressure.

Normally the gas pressure to thesteam generator's burner should be between 15 and 20 PSIG. Using the Gas Booster can increase the supply pressure from 5 to 15 PSIG.The gas supply enters the unitthrough a 11/2" NPT connection onthe right of the referenced photo-graph. In the piping, after the inlet connection, is a low fuel switch, and the normally closed inlet block and bleed shut-off solenoid. At the tee, the gas flows to the inlet of the booster blower. At the discharge of the booster blower is a high temperature switch with manual reset and a temperature gauge. The boosted gas then

passes through awater cooled heatexchanger. After

the heat exchanger the gas thenpasses through the discharge tee,

normally closed block and bleedshut-off solenoid and a check

valve. The boosted gas is then piped by the customer to the

burner on the steam generator.Depending upon the pressureregulator setting, some of the

gas can be by-passed to the intake tee mentioned above.

Ahead of the pressureregulator is mounted a high

fuel pressure switch withgauge and the normally open

block and bleed solenoid whichis used to eliminate the gas pressure in the systemafter shut-down. The Gas Booster only operateswhen the steam generator operates.

Hanson Pipe and Products Canada, Inc., located justeast of the Greater Toronto Area of Ontario, is one

of the most northerly of Hanson’s concrete pipe plants.With temperatures cutting well below freezing during the

winter months, finding a method to heat our aggregateswas critical to meet the Ontario Concrete Pipe Associationstandards for concrete. We must maintain a mean temper-ature of 60 to 80 degrees during the production process.

We investigated severalmethods of heating aggre-gates in early summer 20 0 0 .We found that the mostefficient and environmen-tally friendly method is astate-of-the-art instant steamgenerator manufactured bySteam Engineering. Thisgenerator is based on newtechnology and has prove nitself by providing heat tor aw materials at other com-panies that produce pav i n gstones, barrier walls andready-mix concrete.

The highly efficientsteam generator uses up to50% less fuel than conven-tional boiler systems. The

burner achieves this efficiency by consuming virtually allthe fuel/air mixture with minimal undesirable products ofcombustion. Also, the unit only uses fuel when steam isrequired; therefore, it does not have to maintain a mass ofwater at high temperatures.

An immediate benefit of the system is that steam isavailable on demand. Within 15 seconds of switching onthe m a c h i n e, steam is ava i l a b l e. The unit pressure does note x c e e d 15 psi, thus eliminating the need for a special boilerroom, stationary engineer and high insurance rates.

H.R. Stark, a local mechanical engineering firm, installedthe system in October. The steam lines extend from theunit to the outside aggregate bins and an aggregate storagepad used for storing extra sand and stone.

Just in time for freezing temperatures, steam emanatesfrom our aggregate bins and storage piles. It will take am o n t h of monitoring temperatures before we can developactual preset steaming times.

The steam generator system enables Hanson Canada tomaintain critical concrete temperatures to produce a consis-t e n t , quality product during the cold winter months.

Hanson Canadaheats aggregates, meets standard s

Sand and stone is kept at allowable tempera t u res for winter processing by a highly efficient steam g e n e ration system at Hanson’s Canadian fa c i l i t y.

The aggregate heating steam generator consumes virtually all the fuel/air mixture with minimal undesirable products ofc o m b u s t i o n . HH

The exact date may vary some indifferent parts of the country, butNovember often marks the hot con-crete surcharge season for manyReady-Mix owners and operators.Along with the extra revenue however,comes the same old headache of howto ensure that your product meetsyour customers’ specifications. Manysolve this problem by firing up anold, inefficient hot water boiler, hop-ing they can heat enough hot water tosomehow blend their way throughthe winter without losing customersor loads. Others direct wet boiler-madesteam into bins, causing a whole newset of problems like rusting and satu-rated sand. Still others buy heatedsand for as much as $3.00 a ton!

While there is no definite answerto every situation, Steam Engineeringdoes have a solution for most Ready-Mix owners and operators. We canput an end to your annual struggle of“man versus nature.” The solution toyour winter weather problem startswith the installation of our high-effi-ciency Direct-Fired Steam Generator.These units have been time-tested insome of the coldest parts of Canadato heat water and aggregate either inbins or on pads.

The unique features of our steamgenerators are that they can producesteam in 15 seconds from a cold start,they do not require expensive chemi-cals, and they can save you up to50% on your fuel bills.

Your solution contin-ues with our S t e a mE n g i n e e r i n g Re a d y - M i xAutomation Pa c k a g e.This reliable combina-tion of electronics andmechanics was designedto ensure that you haveyour needed supply ofhot sand and hot waterto get going each andevery day. Picture this: asand pad piped with steam lines,sized to hold your full day’s demand,and a hot water tank with steam pip-ing, capable of handling the first houror so of operation.

Past methods for a mediocre solu-tion have included many operatorsattempting to superheat water up to180°F to compensate for frozenaggregates and to blend with cold wa t e rfor truck side tanks. Such “solutions”have proven to be very inefficient, asthe energy to superheat this volumeof water is extremely expensive andmost water systems are not designedto handle the needed capacity. We’vecome a long way from these outdatedstrategies!

Steam Engineering will programan automation system that will pre-heat your sand pad in the middle ofthe night. As a rule of thumb, onemillion BTU can heat 40 tons of sandto 125°F in one hour. When left out-side, this sand would only lose 10°Fto 15°F per day. With your sand heatedto 125°F, you no longer need tosuperheat water. Still, however, SteamEngineering technology allows youto heat water to 140°F very efficiently,at a rate of 1,200 gallons per hour forevery one million BTU. Our automa-tion system includes a thermocouplethat, when placed in a water tank, will

ensure your ideal temperature is metbefore you open your doors for theday. Then, as water is drawn off andreplaced, the system will start andstop the unit automatically as neededto maintain the desired temperaturethroughout the day.

If your location is not suited forheated pads, then bin heating is asimple alternative. Proper steam pipingin your bins, along with our hot drysteam, will deliver heated sand withconsistent moisture – without damageto your bins. The Steam Engineeringautomation package comes with twovalves, with cross linkage and motor-ized actuator to switch back and forthfrom the sand pad to the water tankautomatically, as programmed.

COLDSTREAM CONCRETEdrycast, wetcast, concrete pipe, andready-mix – four businesses withinthe same industry with very differentapplications. While most companiesin this field just focus on one methodof operation, Coldstream Concreteencompasses all four.

Based in Ilderton, Ontario, BobB r own's family business has evo l ved tomeet the needs of his expanding mar-ket of small towns and rural areas.Coldstream really is a one-stop shop

for any concrete application need,thanks to its commitment to house fourbusiness divisions all under one roof.

Four years ago, Mr. Brown lookedclosely at his growing company, hopingto determine a strategy to consolidatesome of his business and manage hisoverall vision. He realized that all fourof his business divisions shared onecommon necessity: STEAM. The com-p a ny needed to heat sand, defrost grave l ,cure wetcast, drycast, concrete pipe andheat water. At the time, Coldstreamused different heat sources for eachapplication. Mr. Brown first heard ofSteam Engineering from a used-equipment dealer, although he wasalready familiar with the concept ofdirect-fired steam generators. He was

certainly aware of thehuge fuel sav i n g s t h a twould be ava i l a b l e tohis operations with adirect-fired unit, andhe was confident thathis out-dated boilerswere only running at60% efficiency at best.

After reviewing allthe major players inthe direct-fired market, Bob Brow ndecided that Steam Engineering could

meet his needs betterthan any of its com-petitors. Tom ByrnesS r., President of SteamEngineering, and histeam started to workwith Coldstream toengineer an installa-tion solution thatwould fit the bill forthe demanding appli-cations.

B r own's businessconcerns centred on its five concretepipe kilns, three we t c a s t / d r ycast tarpedcuring areas, and a 4,500-gallon watertank, as well as three 120-ton sand andgravel pads, three sand and threegravel bins, and a conveyor belt.To utilize every last BTU, Bobpiped the exhaust from his watertank into his ready mix aggregatebuilding for extra heat. Coldstreamcomprises 19 different heatingapplications in total – a demand-ing sum for any source.

Coldstream represents themost challenging of SteamEngineering's installations todate, including over 1,500 feet ofsix-inch steam-header. The job took over one year to complete,

during which time Brown contracteda local electrical company to designan automation system to manage theday-to-day operations of the direct-fired system.

These days, Bob Brown couldn'tbe happier with his heat source deci-sion. Steam Engineering has reallycome through as a company he cantrust for his current needs, as well ashis future demands. ColdstreamConcrete now understands whydirect-fired steam generators havep r oven themselves over and ove ragain to be the most efficient, cost-e f f e c t i ve, energy-saving heat sourcefor concrete applications. SteamEngineering continues to be a leaderin this field of technology.

At A Glance:

• Acting on Steam Audit recommendations, Continental Mushroom p u rchases an instant steam ge n e rator for mushroom bed sterilization.

• Estimated annual reduction in consumption of natural gas isapproximately 300,000 m3

• Plant qualifies for financial incentive of $15,000 from Enbridge Consumers Gas.

Continental Mushro o m , established in 1973 in Metcalfe,O n t a r i o ,

p roduces 9 million lbs of button mushrooms (agaricus bisporus)

per year for shipments throughout the Ottawa Valley, Quebec

and the Eastern seaboard. Mushroom growing is an exacting

science and steam sterilization plays an important role in

maintaining good growing conditions. Heat alone cannot

e n s u re complete sterilization of wooden growing beds. Steam

is needed to penetrate cracks and crevices. With 33 mush-

room houses, each producing six crops, the facility uses nearly

170,000 lbs of steam a year.

Finding an Energy Efficient and Environmentally Friendly Solution

The Enbridge Consumers Gas steam system audit was conduct-

e d in 1998. This audit found that steam production costs were

high and that most of the steam was being used for sterilization.

It recommended looking for a more efficient system of

steam generation. Michael Fakhouri, an Enbridge Consumer

Gas energy management consultant, recommended an instant

steam generation unit developed by Steam Engineering Inc.

in Aurora, Ontario. Enbridge Consumers Gas connected

Continental Mushroom with the supplier and arranged a visit

to a site already using the technology. Steam Engineering

installed the unit on a test basis in December 1999.

After some fine-tuning and adaptation to the particular site

re q u i rements, this equipment is now being used for mushro o m

house and bed sterilization and a second unit is planned.The

sterilization process re q u i res steam at 65°C for up to 24 hours

for the first round and again for up to 16 hours on a second

round. Reliability is essential. The old steam system comprised

of two boilers (150 hp and 250 hp) operating at 110 psi and

was located in the middle of a 1000 ft long production facility.

Steam was delivered to the mushroom houses through a

system of pipes. Two factors contributed to a high cost of

steam production:

1) boiler efficiencies were only in the 75% range, and

2) there were some heat losses in the piping system.

Multiple Efficiencies

The instant steam generator uses a highly efficient process of

steam production. Air is driven into a mixer-burner, combined

with fuel and ignited. Water is sprayed into the hot gases exit-

i n g the chamber. This creates instant steam. Stack gases are

c a p t u red and combined with steam rather than being vented,

recovering energy that would otherwise be wasted. The re s u l t

is 98% efficiency.

The unit does not re q u i re pre-heating of make-up water. It is

portable and is wheeled from one mushroom house to another

as needed – eliminating piping heat losses. Because the gen-

erator operates on regular water, there is no cost for chemical

t reatment. This produces an environmental bonus: the facility

uses wastewater from the growing process, solving a disposal

p roblem. Since the instant steam generator operates at 4 psi*,

it does not require constant monitoring.

The installation required new water and gas lines to the

individual mushroom houses. Steam Engineering also made

modifications to the original unit to improve its reliability and

weather resistance. Lyle Whitham, Continental Mushroom’s

General Manager, is so pleased with the performance of the

instant steam generator that he is planning to add another. Once

conventional high pressure boilers are completely eliminated,

he expects to see further savings in boiler insurance pre m i u m s .

Multiple Savings

The projected natural gas savings from changing to instant

steam generators are 300,000 m3 valued at $86,000. Chemical

savings are $24,000. Total cost savings may be as high as

$110,000. Continental will re q u i re 2 units at a total installed cost

of $190,000. The simple payback for the project is 1.73 years.

The system brings two enviro n m e n t a l benefits: it uses waste-

water, which was a disposal problem, and it reduces CO2

emissions by over 578,000 kg per year. This project q u a l i f i e d

for a cash incentive of $15,000 from Enbridge Consumers Gas.

Benefits of Instant Steam Generator:

• 24% reduction in steam cost • No stationary engineer re q u i re d

• Fast payback • Reduced environmental impacts

• Potential insurance savings • No chemical treatment of water

Brunswick Smelting and Fertilizer

Brunswick Smelting and Fertilizer, of Belledune, N.B., a division

of Brunswick Mining and Smelting Corporation Ltd., produces

refined lead, dore, copper matte and sulphuric acid, and

diammonium phosphate in its fertilizer operation. Energy is a

very significant part of production costs, and the tough climate

of Northeastern New Brunswick imposes its own energy demands.

Treating energy management as a central element of corporate

philosophy won the company a CEA Provincial award in 1985,

and a National co-winner award in 1987. This year, defying the

law of diminishing returns, their Energy Management Program

projects showed annual savings of $1.3 million for a capital

expenditure of $812,000. with an overall payback period of just

over seven months. For this accomplishment the Brunswick

Smelting and Fertilizer Division has been named national winner

of the CEA 1988 Energy Efficiency Industrial Award.

M r. Jean-Gilles Girard, Coordinator of the Energy Management

Program, describes the overall approach at Brunswick: "It’s a

team effort – we all look for ways of accomplishing top quality

p roduction within the leanest energy output parameters possible."

Winning Strategies

Major and minor initiatives combined to produce the impressive

results of 1987. They include the following:

Boiler Elimination

The fertilizer plant was initially designed to rely heavily on steam,

but replacement of a dihydrate process with a more energy eff i c i e n t

hemihydrate process allowed for further rethinking. Faced with

an expensive retubing, it was decided to eliminate the old boilers

and reduce costs by purchasing new, more efficient technologies.

Steam for startup of the acid attack tank and for ammonia

vaporization is now provided by three Steam Engineering

steam generators rated at 5000 lb/hr at 12 psig each. Building

heating was converted to propane/hot water and propane radi-

ant systems, supplemented by electric baseboard heaters in

offices. Oil and phosphoric acid lines were fitted with electric

heating pads and an oil tank with in-line electric heaters. With

some additional insulation, these steps resulted in a 70%

improvement in energy efficiency.

Acid Plant SO2 Preheater

In the Brunswick acid plant, gas processing is in part auto-

thermal; but startup of the preheaters, and energy requirements

when SO2 concentration was low, were significant because of

air infiltration and heat losses. Reinsulation, and readjustment

to guarantee an SO2 concentration of 5.5%, reduced the oper-

ation of the preheater from 50 hours per month to 12 hours. This

translates into a fuel improvement of 75%.

Sinter Machine Burner Replacement

A sinter machine ignition stove, which had been given uneven

reactions, insufficient sulphur elimination and poor agglomeration,

was replaced with lino-flame burners. The new equipment re d u c e s

operating and maintenance costs, lowers ventilation needs,

increases machine availability and produces a better sulphur

elimination rate, for a 41% improvement in energy efficiency.

D.A.P. Dryer Burner

Another step taken in energy management was the installation

of a more efficient burner for drying granulated product in the

D.A.P. building, using a high pressure oil/mechanical mixing

atomizer. This new equipment reduces oil consumption by 30%

and water consumption by 400,000 gallons/year.

Computerization

Production computerization in the lead refinery was of major

significance for long term profitability. While energy efficiency

gains will amount to a relatively low 5%, gains in improved

operations and increased production capacity are important.

Operators are now supplied with simplified data for analysis,

and response time in critical operations is markedly improved.

Lead Pumping

Traditional lead refining required a series of 19 kettles, holding

between 180 and 200 tonnes each. Transferring bullion through

a complex sequence of steps was potentially dangerous in that

the use of massive perforated buckets and lead ladles could

result in spills. During 1987, a pump system was installed which

i m p roved operations; reducing the need for ventilation and signif-

icantly improving hygiene and the safety of the work enviro n m e n t .

In addition, lead pumping from the final treatment kettle

d i rectly to the casting machine, eliminated the need for two No. 2

oil burners, running 80% of the time. The change produced an

energy efficiency improvement of 90% and improved the work

environment as well, opening up new space in a crowded and

potentially dangerous work area.

Further steps

T h ree further steps made their contribution to an overall excellent

energy management picture. The operation of the slag furnace

baghouse was eliminated by redirecting exhausted fumes to the

main furnace baghouse. The introduction of a system which

uses oxy-propane mix for metal welding and cutting torches

eliminates the need for acetylene, thus improving safety while

reducing labor handling and operating costs. Finally, improved

lighting in offices, parking lots and process buildings – intro d u c-

i n g fluorescent fixtures with prismatic lenses and high pressure

sodium lights in areas where more lighting is necessary, re s u l t e d

in a wattage reduction, for further savings.

Conclusion

The dramatic success of the Brunswick Smelting and Fertilizer

Division’s Energy Management Program ensures that the pro-

gram will be maintained and expanded. An Energy Employee-

Awareness Program has

been set up to recognize

and reward all employee

contributions to this cor-

porate goal. The plan

relies on the skill and

knowledge of a well-

trained and committed

workforce, and ensures

that energy manage-

ment is everyone’s

ungoing concern.

Adding capacity at an older flour mill oftenmeans cramming more equipment

inside an already cramped facility. Star of theWest Milling Co. (www.starofthewest.com)encountered that problem nearly three yearsago at its Ligonier, Indiana facility andturned to Blower Engineering, Lewiston, NY,to help find a solution.

“We were running out of space in theblower room,” explains Gary Pickelmann,corporate milling superintendent for Star ofthe West Milling. “ B l ower Engineeringoffered us an enclosed blower that we couldput outside and we decided to give it awhirl.”

Freeing up space inside the mill is justone of the advantages of placing enclosedblowers outside a facility, Pickelmann says.

“We’ve found that the blowers run cooleroutdoors,” Pickelmann says. “If they runcooler, they tend to last longer.”

Noise ReductionHaving outside blowers also reduces noiseinside the plant, says Pickelmann, addingthat the blowers make very little noise out-side the facility, because the enclosure issound proof.

The enclosure consists of galvanized steelconstruction panels that can be remove dwithout tools. “When you walk by you can hardly hearthem running,” he says.

The 72" x 46" x 64" package weighs approximately2,300 pounds, but is designed so that it can easily bemoved.

“To move it, all you have to do is disconnect the piping and wiring and pick it up with a forklift,”Pickelmann says.

The enclosed 2,400 rpm blowers have a capacity of500 standard cubic feet per minute (scfm) at 14 poundsper square inch (psig). The blowers are powered by a 50 hp, 1,800 rpm motor.

Pickelmann says Michigan-based Star of the WestMilling won’t hesitate to use outside blowers at some ofits other facilities, if space becomes an issue.

“We’ve talked about doing it at our Frankenmuth,Michigan facility,” Pickelmann says.

Putting an enclosed blower outside can reduce noise andincrease production space inside the plant

Acoustical Enclosure for Blowers

The Blower Engineering Tr i - L o b e® Enclosed Blower, pictured above, is designed

for outside use, freeing up space inside the mill and dramatically reducing the

noise level to less than 80 dBa.

With the need to boost cfm output topower all the new equipment, the com-pany decided to use the opportunity toreplace virtually all of the blowers pow-ering the pneumatic systems in the grainelevator and the mill. And General Millschose to standardize with 40 blowers,all supplied by Blower Engineering,Lewiston, NY (800-388-1339).

REPLACING A HODGE-PODGE“We had a real hodge-podge of blowersaround the plant, MDs, Duroflows,Sutorbilts,” says Milling SuperintendentEd Klein. “We’d been having a lot ofproblems with some of them, and therewas a lot of dow n t i m e.” He notes that bystandardizing on a few models suppliedby a single manufacturer, the companycould streamline its maintenance proce-dures and hold parts inventory to aminimum.

Klein and Plant Manager Jeff Shapirofirst tried out a recommended blowerafter meeting with Blower Engineeringrepresentatives at the 1994 Associationof Operative Millers Trade Show inCalgary, AB. They tried one blower on arailcar loadout system, then two otherselsewhere in the plant, and liked theperformance. Among the features Kleinparticularly likes:• A tight oil seal design for long life with

relatively low maintenance.• Reliance on a baffle-type muffler

system rather than insulation for rela-tively quiet operation.

Working closely with Blower EngineeringPresident Tom Byrnes Sr., General Millshad the following blower modelsinstalled this year at Great Falls.• Four Model TL 30 blowers, ranging in

operation from 1,750 to 3,241 rpmand in output from 90 to 200 cfm.

Uses – enrichment, fluidizing blower,flour feed-in, screenings.

• Fifteen Model TL 60 blowers, rangingin operation from 1,573 to 2,811 rpmand in output from 200 to 467 cfm.Uses – wheat conveying in portions ofthe cleaning house; flour conveying tobulk bins, the rebolter, and elsewherethrough the mill; screenings; bran andshorts mill lift; semolina conveying;providing air for the C-mill and clean-ing house.

• Eight Model TL 80 blowers, ranging inoperation from 1,460 to 2,380 rpmand in output from 450 to 860 cfm.Uses – separator to surge bin, storagebin to surge bin, general flour convey-ing, storage to metal detector, mois-ture control to bin, and flow-throughbin to storage bin.

• Twelve Model TL 90 blowers, rangingin operation from 1,801 to 2,067 rpmand in output from 860 to 946 cfm.Uses – storage to cleaning house, gen-eral wheat conveying, general flourconveying, wheat tempering system,conveying finished semolina to thePasta Montana plant.

• One Model TL 100 blower, operatingat 1,977 rpm and generating 1,242 cfm,for moving flour from bulk storage tothe packing line.

SPACE CONSIDERATIONSPerhaps the biggest challenge in theGeneral Mills blower project was thelimited space ava i l a b l e, two rooms in themill basement. The larger of the tworooms was only 222 inches wide x 268inches long, and neither room was largeenough to admit a forklift. In some cases,2,000 lb.-plus blowers had to be liftedby a ceiling-mounted hoist to within sixinches of the ceiling. To make sure blowe r s

were lifted along their center of gravity,Byrnes designed a lifting lug consistingof a 1/2-inch-thick steel plate with threeholes two inches apart. The lug was sus-pended directly beneath the hoist, andthe hoist chain could be passed throughwhich-ever hole allowed the blower tobe lifted closest to its center of gravity.Another space-saving suggestion fromGeneral Mills – triple-stacked blowerson a frame designed by Byrnes withconsiderable input from General Millsengineers. Byrnes says he recommendeda 5” by 5” steel tubing for the frame. Thee x t r a - h e avy-duty construction contributesto reduced vibration and quiet operation.

In addition to the blowers, each ofthe blower rooms is equipped with alarge fan to bring in cooling air.

Klein says the blower system has per-formed well so far and has requiredminimal maintenance. “All you need todo is change the oil and make sure thefilters are clean,” he says. “Ideally, youshould do that once a month.”

One of the largest expansion projects in the flour milling industry this year has beenat General Mills Inc. in Great Falls, MT. Utilizing new equipment supplied by BuhlerInc., Minneapolis, MN (612-545-1401), the company doubled the capacity of itswhite flour/durum semolina swing mill to 7,000 cwts. per day and added a new3,000-cwt.-per-day durum mill, which will supply semolina to a new Pasta Montanapasta plant adjacent to the General Mills property.

Blower Makeover in MontanaFlour mill installs 39 new blowers as part of major expansion.

The ADM Milling plant at Hudson,NY, which produces flour from hardwheat in two milling units, was hav-ing continuing problems with a pairof blowers moving flour through a 6” conveying line.

The system included a 125-hpmotor that drove the two blowers run-ning in parallel. They supplied air tothe 290’ conveying line, 200’ horizontaland 90’ vertical, with a capacity of upto 450 cwts. per hour. Line pressurewas 10 psi.

The problem was that the blowerswere not sturdy enough to withstandthe heat generated in the productionprocess. They would develop oil leaks,and without lubrication for the gearsand bearings, they quickly broke dow n ,halting production. The line had gonethrough four blowers in less than a ye a r.

FINAL STRAWThe plant superintendent at Hudsonknew he had to take drastic stepswhen both blowers on the line had tobe replaced within 48 hours. He andthe plant manager contacted ADMMilling’s regional superintendent andmilling engineer at their headquartersin Salina, KS.

The milling engineer suggestedusing a new, heavy-duty blower fromBlower Engineering Inc., Lewiston NY(800-388-1339). One of Blowe rE n g i n e e r i n g ’s blowers had been installedseveral months earlier at a businessnot far from ADM Milling’s Salinaoffices, and the engineer had beenimpressed with its durability, energyefficiency, and low noise production.

At Hudson, engineers calculated howmuch air volume would be requiredfor the 290’ line and relayed thatinformation to Blower Engineering.Based on that information, BlowerEngineering recommended installinga single TL-100 blower, capable of

producing up to 1,300cfm air vo l u m e. Theblower came completewith base, dischargesilencer, intake filter/s i l e n c e r, belt guard,check va l ve, pressurerelief valve, gauge, anddrive.

The package wa sshipped completelyassembled to Hudson.ADM Milling suppliedand mounted its own75-hp motor to run theblower. The old blowerpackage was removed,and the new TL-10 0was placed in positionand hooked up.

LOW NOISE PRODUCTIONWhen the motor wa sstarted, the maintenance staff wasn’tquite sure the unit was running, sincethe TL-100 was inside a blower room,and they could not detect any increasein noise over the other blowers in theroom.

After they determined the blowerwas operating, they introduced flourinto the air line. The line pressure wasnoted at 9 psi, and the amperage drawon the motor was 40 amps less thanthe old blower package. The volumeof flour moved was roughly the sameas with the old package, and the pres-sure and amp draw remained constantover the continuous 24 hours that itwas monitored.

The TL-100 also ran at a cooler tem-perature than the previous blowe r s, andelectricity saved by the unit allowed theplant to pay for the new installationin less than eight months. Specialists atB l ower Engineering cite several reasonsfor the improved performance:

• Careful machining of blower com-ponents produces closer clearancesbetween the impeller and housing,so it takes less energy to run it.

• The shaft is 1/2” to 1” bigger indiameter than in the older units,and is mounted on bigger bearings.The heavy-duty construction is stur-dier than the older units.

• The design of the TL-100 eliminateslip-type oil seals in favor of non-contacting seals. Thus, there is nocontact between seal and shaft,reducing friction and the amount of energy needed to turn the shaft.The reduction in friction also contributes to cooler operating temperatures.

Since the installation of a TL-10 0b l ower package, ADM Milling hasapproved two other blow lines forc h a n g e over to the new heav y - d u t yblowers.

Blower ReplacementNew heavy-duty unit improves performance, energy efficiency.

That’sespecially true for a pair of 150-hpblowers on the mill’s ground floor.They generate roughly 14 psi, +/-1 lb.,to blow finished semolina flourthrough a pair of 8”diameter, 1,100’long pipes, which carry the flour to aBorden pasta plant to the south of theU.S. Durum Milling property. Bordenis one of U.S. Durum Milling’s majorcustomers, though not the only one.

“Until 1991, the original blowerson those pneumatic lines wouldn’tlast long in that application,” saysMark Williamson, director of milling.“They were running nearly 24 hours aday, seven days a week.”

According to Mark Dexheimer, amaintenance worker and millwrightat the plant, one of the two blowersblew out its seals in 1991 and beganthrowing oil. This was after the unithad been rebuilt once. The companydecided to try something different.

BIGGER UNITAfter looking at a number of blowers,U.S. Durum Milling selected a TL-130blower from Blower Engineering Inc.,Lewiston, NY (800-388-1339). Oneof the most noticeable features of aTL-130 is its large size compared tothe original blower – 26” wide x 32”long x 25” high for the Blowe rEngineering model vs. 19” wide x 40”long x 21” high for the older blower.Dexheimer notes that the steel frameon which the older unit had beenmounted had to be extended out toaccommodate the TL-130.

Tom Byrnes Jr., vice president ofBlower Engineering, comments thatthe beefier design of the TL-130 blow-er allows it to generate the same levelof air pressure with less energy. It also

operates with less vibration, con-tributing to longer work life. Amongadditional features:

• The TL-130 blowe r ’s components aremachined to extremely tight toler-ances, producing closer clearancesbetween the impeller and housing,reducing the amount of slip.

• The shaft is 1/2”to 1”larger in diame t e r

than in comparable models, and it ismounted on larger bearings.

• The TL-130 utilizes non-contactingoil seals as opposed to lip-type seals.Since there is no contact betweenseal and shaft, there is less friction,reducing the amount of energyrequired to turn the shaft and result-ing in cooler operating temperatures.

Bigger Blowers, Lower Energy UseMissouri durum miller documents energy savings from new blowers.

Two Blower Engineering TL-130 blowers provide air pressure to move finished semolina flour.

Finished semolina travels 1,100 feet from the U.S. Durum Milling mill to the neighboring Borden pasta plant.

DUST COLLECTOR FILTER SLEEVE CLEANING DEVICE

Operation• Inside the casing, two brushes rotate in opposite directions. Through slits in the guiding

tube, the brushes contact the surface of the filter sleeve and mechanically clean the

sleeve. The contact pre s s u re is regulated through an adjusting scre w. The brushes can be

removed thro u g h the front cover plate. The Bag Cleaner is connected to the plant vacuum

clean up system. The gathered dust is collected in the bottom cone and withdrawn

through the vacuum system.

Features• Can be used on 4" and 5" dust collector bags with circular support cages without

removing the dust collection filter sleeve from the cage;

• Can be used with any kind of dust (motor shafts are sealed);

• Removes incrustations that regular cleaning cannot handle;

• Each brush is driven by an electric motor;

• The brush contact pressure can be adjusted using spring loaded adjusting screws;

• Brushes are constructed with strong nylon bristles arranged concave and adapted

to the sleeve adapter;

• After cleaning, the filter bags and cage can be reinstalled in the collector.

Components• Brush Housing with stand – sanitary construction (41" high x 22" long x 24" wide,

weighing 200 lbs.);

• One – bottom aspiration transition for field hook up to

plant vacuum clean-up system,

(1 1/2" or 2" connections available);

• Two – 3/4 HP TEFC Motors, (230/460, 575/3/60) –

accepted as explosion proof for milling applications

(Class II, Div. 2, Group G);

• Two – rotary brushes;

• One – 6" ID Guide Tube with 5" ID adapter for use with

4" and 5" filter bags;

• One – Control Panel – ready for field connections –

230/460, 575/3/60 NEMA 5 & 12 enclosure.

Benefits• Down time for bag cleaning is reduced;

• Labour saving – no need to strip bags from their cages;

• Lessens risk of bag damage – no need to strip bags

from their cages;

• Less mess to clean up after cleaning operation –

no need to strip bags from their cages;

• Less expensive than laundering;

• Does not remove eggshell or singed finishes as can

happen with laundering.
