(Draft for Review and Comment January 2014)

S4.1 – Scope

NBIC Part 1, Section 6, Supplement 4 provides requirements for the installation of Biomass (Wood/Solid Fuel) Fired Boilers as defined in NBIC Part 1, Glossary.

S4.2 PURPOSE a) The purpose of these rules is to establish minimum requirements, for the installation

of Biomass Boilers. b) It should be recognized that many of the requirements included in these rules must be

considered in the design of the boiler by the manufacturer. However, the owner-user is responsible for ensuring that the installation complies with all the applicable requirements contained herein. Further the installer is responsible for complying with the applicable sections when performing work on the behalf of the owner user.

c) This supplement provides requirements for the installation and control of boilers which use biomass as a major fuel component and will address the differences that occur when solid fuels, such as Biomass, are being used. Thus the primary thrust of this section will be directed toward the control of the fuel handling and distribution systems.

d) Fuels will vary widely depending upon source, moisture content, particle size and distribution, however once the fuel has been established, the owner-user should adhere to the original specification, as closely as possible in order to minimize handling, combustion and emissions problems.

e) Additionally the emissions control equipment is designed around the initial fuel specification. Any changes in fuel fired will impact on the performance of the various elements of the emissions control system.

f) Biomass boilers and boiler rooms require additional considerations than traditionally fueled boilers that may include

Transportation of the fuel from a storage facility to a metering device within the boiler room

Transportation of the metered fuel to the boiler, for distribution to a combustion system whether it be a grate upon which the combustion takes place, a bubbling fluidized bed, circulating fluidized bed or suspension burner.

In grate based combustion systems combustion air is typically divided into an underfire air system and an overfire air system, each of which must be closely controlled in order to produce clean, efficient combustion.

Induced draft fans to overcome the pressure drop of the emissions control equipment

A fly ash or carbons recycle system, to return unburned carbon to the combustion zone.

An ash removal system, to move ash from the boiler and emissions control equipment to suitable cooling and storage area.

S4.3 – Determination of Allowable Operating Parameters

The allowable operating parameters of the combustion side shall be installed in accordance with jurisdictional and environments requirements, manufacturer’s recommendations, and/or industrial standards, as applicable.

S4.4 – General Requirements

a) Power Boilers utilizing biomass as the primary fuel source shall meet the requirements of NBIC Part 1, Section 2 and this supplement.

b) Steam Heating, Hot Water Heating, and Hot Water Supply Boilers utilizing biomass as the primary fuel source shall meet the requirements of NBIC Part 1, Section 3 and this Supplement.

S4.5 – Fuel System Requirements and Controls

a) Fuel Transport Systems shall address preserving fuel particle size distribution, fire prevention, and the suppression of fires or explosions. In a single installation various types of fuel transportation systems may co-exist, the most common systems are

Conveyor systems- In these systems fuel is dropped onto a moving belt, bucket elevator, drag link conveyor or a screw or auger mechanism. Speed of the conveyor may be varied to meet fuel demand.

Lean phase pneumatic systems - In these systems fuel is dropped into a moving airstream, mixes with the air, and travels through a pipe at a velocity of approximately 5000 ft/min. Air pressures are in the region of 25 inches water column.

Dense phase pneumatic systems – An intermittent or batch feed system, in which fuel is dropped through a valve (dome valve) into a pressure vessel. When the vessel is filled, the valve is closed, air at a pressure between 30

to 100 psig is admitted and the fuel leaves the vessel in the form of a “slug”. The sequence then repeats. (Note that these systems are also used for ash handling.)

a) Fuel Transport Solid Fuel Metering Systems vary depending upon the fuel used and the particle size distribution, these metering systems include but are not limited to:

Variable speed augers Variable speed, helically flighted, augers can be located in the bottom of a fuel metering bin. Alternatively they could be a part of a retort type stoker. The auger dimensions, flighting, and speed range are selected on the basis of fuel being burned, its size range, heating value and required boiler turndown range. The metered fuel typically is then dropped into the throat of a venturi, (or in some cases a plain pipe) though which the fuel transport air flows to carry the fuel into the boiler combustion zone, for distribution on a grate, upon which the burning of the fuel takes place.

Variable speed air-lock valves This valve is basically a rotating slotted cylinder, operating within an outer cylinder, suitably sealed to prevent leakage. Rotational speed and slot dimensions can be varied to accommodate changes in fuel flow rate. The fuel passing through the valve, typically, is deposited onto a moving grate type stoker.

Variable stroke rams This is another device that can be located on the bottom of a metering bin, is typically used on smaller units and is essentially a batch feed mechanism. The stroke of the ram is adjusted to set fuel flow rate.

S4.6 – Combustion Requirements

a) Overfire Air/Underfire Air Distribution When solid fuels are burned on a grate, rather than in fluidized bed units or in suspension, it is normal practice to introduce some of the combustion air under the grate, or bed, and the remainder over the bed. In many cases fuel transport air becomes a part of the over-the-bed combustion air. The proportioning of the overfire to underfire airflow rates is dependent upon several factors, such as fuel particle size, fuel density, burn rate and volatiles. In general the objective is to get as complete a burn on the grate as possible, without creating large quantities of particulate emissions, and then using the overfire air to complete burning of the volatile and small particulate matter, leaving the fuel bed. Loss of combustion air from either the underfire or overfire source shall cause shutoff of the fuel supply and a lockout condition. The control system shall be capable of maintaining the correct relationship between underfire air and overfire air, over the complete firing range of the boiler, while promoting complete burning with minimum particulate emissions.

b) Programming Controls Programming controls may be relay based, or on more current units, PLC based. Interactive graphics displays may also be incorporated into the system. Access to PLC based controls and interactive graphic displays shall be limited to qualified individuals and password protected. PLC functions shall be confined to the normal boiler operating logic, covering startup, interlocks, and normal shutdown sequences. PLC logic shall not interfere with, or over-ride safety controls, which cause boiler safety shutdown when activated. Consideration should be given to having the PLC logic comply with the requirements of NFPA-85.

c) Pre-firing Checks/interlocks In addition to the Safety Controls defined in Section 4.5 and 4.6 proof of air handling fans or blowers are operating properly shall be required. This includes:

Induced draft fans

Fuel transport fans

Underfire air and Overfire air fans, and

Carbon, or flyash, re-injection fans.

In cases where variable speed drives are used on fans, the combustion system manufacturer’s instructions shall be followed in terms of the allowable upper and lower limits of the power supply frequency (Hz).

d) Pre-purging Pre-purging the boiler and its venting system shall be required. Unless defined otherwise by the manufacturer of the fuel burning equipment, the pre-purge may be achieved by operating the induced draft fan prior to starting the remaining fans in the installation. Purge air volume shall be set during commissioning by the combustion system manufacturer, or the manufacturer’s representative, in accordance with applicable Codes or Standards and shall not be capable of being reset by operating personnel.

e) Ignition Systems Solid fuel ignition systems and/or methods can vary from the placement of manually ignited, oil soaked rags on the fuel bed, to gas or oil fired pilot burners or lances but in all cases shall be in accordance the manufactures recommendations.

f) Firing Rate Control and Fuel/Air Ratio Control The control system shall be capable of maintaining the desired air to fuel ratio over the entire firing range of the boiler, while promoting clean, stable combustion.

g) Re-injection Systems In installations where fly ash is re-injected from a multi-cyclone collector into the combustion zone for carbon re-burn; precautions should be taken to ensure that plugging of the reinjection pipe work does not occur. Consideration should be given to installing cleanouts in the pipe work.

h) Shutdown and Post Purge Unless the boiler manufacturer’s instructions state otherwise, the fuel supply shall be terminated at shutdown, and the overfire air should remain on until the fuel bed is burned out, and the residue cooled.

New definitions

Conveyor system(s) - A fuel transport system utilized on biomass boilers that drops fuel onto a moving belt, bucket elevator, drag link conveyor or a screw or auger mechanism. (The Speed of the conveyor may be varied to meet fuel demand.) Lean phase pneumatic system(s) - A fuel transport system utilized on biomass boilers that drops fuel into a moving airstream, mixes with the air, and travels through a pipe at a velocity of approximately 5000 ft/min. Air pressures are in the region of 25 inches water column. Dense phase pneumatic system(s) – A batch feed transport system used on solid fuel fired boilers for both fuel delivery and/or ash removal. In this system the material to be transported is dropped through a valve in a pressure vessel. When the vessel is filled the valve closes and air at a pressure from 30 tom 100 psig is admitted and the material leaves the vessel in the form of a “slug”. The sequence then repeats.

Subject: Part 2, Supplement 2, S2.6.2 – Ultrasonic Thickness Testing

File Number: NB11-1101

Proposal: Add more information for the evaluation of local pitting corrosion versus general corrosion.

Explanation:

a) Add a new section S2.6.3 to better define the evaluation of corrosion and the effects on MAWP.

b) Remove Note b) from S2.6.2

New Proposed text for S2.6.3

S2.6.3 Evaluation of corrosion

S2.6.3.1 Line and Crevice Corrosion

Line and Crevice corrosion may be disregarded for MAWP calculations when:

a) The thickness of the remaining material is at least 75% of the required thickness per the MAWP calculations.

b) The total length does not exceed 2 inches (50 mm).

S2.6.3.2 Widely Scattered Pits

Widely scattered corrosion pits may be disregarded for MAWP calculations when: a) The depths of the pits are such that the remaining material shall not be less than 50%

of the required thickness per the MAWP calculations. b) The total area of pits, below the required thickness per the MAWP calculations, does

not exceed 7 sq. inches (4500 sq. mm) within any 50 sq. inches (32000 sq. mm) area. c) Total length of pits in an 8 inch (200 mm) straight line cannot exceed 2 inches (50

mm).

S2.6.3.3 Locally Thinned Areas

Locally thinned areas (LTA), 3 inch (75 mm) in diameter or less, may be disregarded for MAWP calculations when:

a) The average depth of the corrosion is such that remaining material shall not be less than 75% of the required thickness per the MAWP calculations.

b) The thickness at the thinnest point shall not be less than 50% of the required thickness per the MAWP calculations.

c) The minimum distance between the boundaries of two locally thinned areas (MDLTA) must be greater than the average diameters of the two locally thinned areas (LTA) multiplied by 3.0. See Figure S2.6.3.3

S2.6.3.4 Generalized Thinned Areas

For corroded area’s exceeding the specifications in S2.6.3.1, S2.6.3.2, and S2.6.3.3, the thickness may be averaged over an area not exceeding the UT grid size specified in S2.6.2 c) and S2.6.2 d). The thickness at the thinnest point shall not be less than 50% of the required thickness per the MAWP calculations and the average shall not be less than 75% of the required thickness per the MAWP calculations.

When general corrosion is identified the exceeds the limits set forth in this paragraph the pressure vessel MAWP shall be de-rated to meet these requirements, or removed from service until it is repaired by a qualified organization.

Note: These guidelines in S2.6.3.1, S2.6.3.2, S2.6.3.3 and S2.6.3.4 are to be used in areas of thinning due to corrosion. Area’s where plates have been formed to make corners and radius will be thinned due to the forming process and should not be taken into account when calculating MAWP.

Subject: Part 2, Supplement 2, S2.8.1 SAFETY VALVES File Number: NB13-0901 Proposal: Add language to address the safety valve discharge piping. Explanation: Add new items 8-12 Add the following:

8) The safety valve(s) shall be connected so as to stand in an upright position with the spindle vertical.

9) The discharge from the safety valve(s) shall be arranged that there is no danger of scalding either the operator(s) or individuals who may be in the vicinity of the boiler. If the valve(s) is a top discharge design, no discharge piping is required. If a side discharge design valve(s) is used, an elbow should be attached to the outlet to assure a vertical discharge. The elbow must be located as close to the valve(s) as possible to minimize reaction moment stress.

10) Provision for ample gravity drain shall be made in the discharge pipe at or near each safety valve, and where water can collect.

11) If the boiler is equipped with a canopy, the elbow may be other than 90 degrees to direct the discharge out from under the canopy, while still directing the discharge to a safe location. The elbow must be located as close to the valve(s) as possible to minimize reaction moment stress.

12) If the boiler is equipped with a canopy, the discharge may be piped through the canopy. When the discharge piping is piped through a canopy, the elbow must be located as close to the valve as possible to minimize reaction moment stress. The discharge piping may be a larger pipe than the discharge size of the valve. Discharge piping shall be completely supported separate from the valve and elbow so no extra loading is transmitted to the safety valve(s).

Code Interpretation 

Inquiry: Does the NBIC Part 3 in Section  3.3.4.3 d)  require tubes below “t min” to be repaired?   

Reply: No. The NBIC Part 3 does not provide rules for determining when a repair must be performed.  

Background Information:  In this particular case, a boiler tube failed due to OD corrosion in a division 

wall near the crouch area.  Upon review, it was found that several tubes exhibited corrosion due to 

waterwall washing and migration of the water through the insulation to the tube surface over the 

course of 60 years of operation.  Several wall thickness readings were taken in areas where this 

corrosion was visually detected and several areas were found below “t min”.  Many areas were weld 

repaired restoring wall thickness in these corrosion areas to at least 80% of “t min”.  

The boiler OEM previously issued a bulletin which allowed the owner‐operators to operate boilers with 

tube wall thicknesses down to 70% of “t min” if certain conditions are met in the bulletin. These are 

presented in the OEM bulletin (attached) and all conditions have been met in this bulletin. The owner 

presented this information to the Commissioned Inspector (CI) for all tubes that were less than “t min” 

but greater than 80% and the CI referred to the Jurisdictional authority.   

The jurisdiction interprets this section as,  

The owner‐user believes the intent of this section includes conditions where wall thicknesses are less 

than t‐min.  This is further confirmed by the last sentence in this section, “This may be necessary when 

considering such items as size limitations of repaired areas, minimum tube thickness to be repaired, tube 

environment, location of tube in the boiler, and other similar conditions”. The owner believes “minimum 

tube thickness” applies to conditions where actual wall thickness is less than “t min” and continued 

operation of this boiler where tube thicknesses meets 80% t min and is based on reasonable analyses 

meets the intent of this section of the code.    See interpretation 98‐05

2.5.3 alternative Welding metHods WitHout PostWeld Heat treatment

a) Under certain conditions, postweld heat treatment, in accordance with the original code of construction, may be inadvisable or impractical. In such instances, the following alternative methods may be used.

b) Competent technical advice shall be obtained from the manufacturer of the pressure-retaining item or from anotherqualifiedsource,suchadvicebeingespeciallynecessaryifthealternativeistobeusedinhighlystressed areas, if service conditions are conducive to stress corrosion cracking, if materials are subject to hydrogen embrittlement, or are operating at temperatures in the creep range, or if the alternative is being considered for “on-stream” repairs or “hot tapping” on piping systems. Selection of the welding method used shall be based on the rules of the original code of construction together with the above mentioned advice concerning the adequacy of the weld in the as-welded condition at operating and pressure test conditions.

c) When reference is made in this Section to materials by the ASME designation, P-Number and Group Num-ber, the requirements of this Section apply to the applicable materials of the original code of construction, either ASME or other, which conform by chemical composition and mechanical properties to the ASME P-Number and Group Number designations.

d) The detailed welding methods listed in the following subsections may be used as an alternative to post-weld heat treatment (PWHT). NBIC Part 3, 2.5.3.1 is a method in which the welding procedure requires an elevation of the preheat temperature. In contrast, NBIC Part 3, 2.5.3.2 thru 2.5.3.5, are methods in which the welding procedure requires the use of a temper-bead welding technique. In 2.5.3.5 is a method in which the welding procedure used for joining dissimilar materials requires either an elevation of the preheat temperature or a temper-bead welding technique, depending on the chemical composition of the basemetalthatisjoinedtoanausteniticsteel.Temper-beadweldingprocedurenomenclatureisdefinedin Section IX of the ASME Boiler and Pressure Vessel Code. Typically, this technique minimizes heat input of the initial beads, thus limiting heat beyond the weld heat-affected zone (HAZ) of the base metal. Heat input shall be increased for successive beads in accordance with the rules of QW-290 for temper beadweldinginASMESectionIX.TheWeldingProcedureandWelderPerformanceQualificationsshall,in all cases, be in accordance with the requirements of the latest Edition of Section IX of the ASME Boiler and Pressure Vessel Code.

e) Nondestructive Examination of Welds

Prior to welding, the area prepared for welding shall be examined using either the Magnetic Particle (MT) ortheLiquidPenetrant(PT)examinationmethodtodeterminethatnodefectsexist.Afterthefinishedweldhas reached ambient temperature, the weld shall be examined again by either of the above methods to determine that no defects exist using acceptance standards acceptable to the Inspector or original code of construction. In addition, welds greater than 3/8 in. (9.6 mm) deep or welds in a boiler, pressure vessel, or piping system that were originally required to be radiographed by the rules of the original code of con-struction, shall be radiographically examined. In situations where it is not practical to perform radiography, the accessible surfaces of each non radiographed repair weld shall be fully examined using the MT or PT method to determine that no defects exist and the maximum allowable working pressure and/or allowable temperature shall be re-evaluated to the satisfaction of the jurisdiction at the location of installation.

f) Methods that may be used as alternatives to postweld heat treatment are described in the following sub-sections.
