Here’s a little secret….

Y t t iYour steam system is costing you thousands ofcosting you thousands of

dollars each year in d !!!!!!wasted energy!!!!!!

Your lucky day!

You can capture mostYou can capture most of these losses with a little

information, a pipe wrench and some elbowwrench and some elbow

grease

Where do you begin?Where do you begin?

Develop a working knowledge of best practices for laundry and dry cleaning boiler p y y goperators.

Understanding the basicUnderstanding the basicUnderstanding the basic Understanding the basic metrics of steam systemsmetrics of steam systems

BTU is the energy required to raise one pound of water one degree Fahrenheitp g1 Bhp = 42,500 BTU (or 10 kw electric)100 000 BTU = One Therm100,000 BTU = One Therm1 cu.ft. of natural gas = 1,050 BTU approx.1 kilowatt = 3,413 BTU

Metrics (cont.)Metrics (cont.)

To calculate the required input for a boiler: Bhp x 42,500 = BTU inputp , pi.e. 15Bhp x 42,500 = 630,000 BTU inputTo calculate fuel requirement:To calculate fuel requirement:BTU input/1,050 = cu.ft.per hour/60 = cu.ft.

per minuteper minutei.e. 630,000/1,050 = 600/60 = 10 cu.ft. per minute

Verify your operating efficienciesCheck incoming gas pressureCheck incoming gas pressureClock the gas meter to see that the boiler is firing on rategCheck the draft in the stackCheck the stack for excessive heat loss orCheck the stack for excessive heat loss or restrictions

Operating Efficiency is MoreOperating Efficiency is MoreOperating Efficiency is More Operating Efficiency is More Than Just Combustion!Than Just Combustion!

A stack test measures the following:

S kStack gas temperatureMake-up of the gases in the boiler stackCalculates the heat lost due to the hot gases exiting the boiler stackCombustion efficiency as a percentage of total available BTU’s

Operating Efficiency is More Operating Efficiency is More p g yp g yThan Just Combustion!Than Just Combustion!

In a stack test for efficiency, the following areas of heat loss are not measured:

Heat loss from the boiler casing to ambient air Radiant heat loss from the return tankRadiant heat loss from the return tankPre- and Post-purge losses w/ forced draft burnersHeat lost through scale build-upHeat lost through scale build upHeat lost at idling or high turn-downsHeat lost at morning start-upsHeat lost at morning start ups
