steam boiler Agent capacity vs pressure

Section 23 52 39 - LOW-PRESSURE STEAM BOILERS

W = boiler capacity (Btu/h, kW) h g = enthalpy steam (Btu/lb, kJ/kg) h f = enthalpy condensate (Btu/lb, kJ/kg) m = steam evaporated (lb/h, kg/s) Boiler Horsepower - BHP. The 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 o F, with feedwater at 0 Psig and 212 o F.

Steam Capacity Conversion Table | Industrial Controls

Shell boilers are often operated with feedwater temperatures lower than 100°C. Consequently the boiler is required to supply enthalpy to bring the water up to boiling point. Most boilers operate at pressures higher than atmospheric, because steam at an elevated pressure carries more heat energy than does steam …

Water Handbook - Steam Purity | SUEZ

Low-capacity, low-pressure boilers (usually fire-tube boilers) rely principally on simple gravity separation of steam and water. At 200 psig and saturation conditions, the density of water is 115 times greater than that of steam. Test results showing the effect of antifoam agents on steam purity in experimental boilers. X.
