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.

Get a QuoteEach boiler is given a boiler horsepower (BHP) rating based on the steam output capacity at 212°F and 0 psig. For this calculation, you will enter the steam load in pounds per hour, which will be divided by a constant of 34.5. This number represents the thermal energy rate required to turn 34.5 lbs of water at 212 °F to steam in one hour.
