Learn MoreMar 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.

Learn MoreSaturated Steam is pure steam at the temperature that corresponds to the boiling temperature of water at the existing pressure. Absolute and Gauge Pressures Absolute pressure is pressure in pounds per square inch (psia) above a perfect vacuum. Gauge pressure is pressure in pounds per square inch above atmo-spheric pressure which is 14.7 pounds per

Learn MoreEach 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.

Learn MoreUnfortunately, the common practice is to use the conversion factor of 34.5 lb / hr hp to calculate the boiler generated steam rate without considering that the boiler does not work at atmospheric pressure. ex. 500 hp x 34.5 lb / hp hr = 17,250 lb / hr produced by the boiler. This is what we call the nominal boiler …

Learn MoreThe Boiler Horsepower (BHP) is the amount of energy required to produce 34.5 pounds of steam per hour at a pressure and temperature of 0 Psig and 212 ℉, with feedwater at 0 Psig and 212 ℉. "Boiler horsepower, a unit of measurement of power of steam boilers" from Wiki.
