Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
Dec 13, 2010 · Heating Water with Steam Example: How many lbs per hour of steam is need to heat 40 gallons per minute flow rate of water from 60 ° F to 180 ° F? Sizing a Boiler Feed Pump Receiver. The receiver tank should be able to hold five minutes worth of condensate for boilers up to 200 BHP and 10 minutes of condensate for boilers over 200 BHP.
Oct 10, 2016 · This one pound of steam has a total of 1,150 btus of heat. One pound of steam at 0 psig or atmospheric pressure (14 pounds absolute pressure), such as in an open pan, occupies 26.8 cubic feet of volume. At 50 psig pressure, the pound of steam has a total of 1,179 btus, but the volume has decreased to 6.7 cubic feet.
Oct 10, 2016 · At 100 psig pressure, the total heat has increased to 1,189 btus, but the volume has decreased to 3.9 cubic feet. If the pound of steam pressure is raised to 150 psig pressure, the total heat increases to 1,196 btus per pound and the volume has dropped to 2.75 cubic foot per pound. Psig stands for the pressure shown on the pressure gauge.
