W = boiler capacity (Btu/h, kW) 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.
Boilers are aimed to produce steam (saturated or super saturated) for commercial or industrial uses. Since capacities for industrial uses are higher compared to commercial ones, so they are often indicated with bigger unit i.e. tons/hr. of steam f
The real capacity will be 16,737,500 = / (1194.2 - 148) = 15.998 lb / hr The difference between the nominal capacity and the real capacity in this example appears to be low, but it is significant because it represents an increase of 8% of the capacity. If a boiler is over fired to its nominal capacity, the result will be a reduction in the

Steam pipes can be sized with the table and diagram below - pressure in bar, velocity in m/s and capacity in kg/h. Sizing Steam Pipes - Imperial units ; sizing steam pipes in pdf-format; Steam velocities of 25 m/s are in general sufficient for most saturated steam applications. Sizing Steam Pipes - Imperial units
It is common to express the output of fire tube and water tube steam boilers in Boiler Horsepower, MBTU or in Pounds of Steam delivered per hour. W = (hg - hf) m where W = boiler capacity (Btu/h) hg = enthalpy steam (Btu/lb) hf = enthalpy condensate (Btu/lb) m = steam evaporated (lb/h) Calculate the boiler capacity for example:
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.
The ‘from and at’ rating is widely used as a datum by shell boiler manufacturers to give a boiler a rating which shows the amount of steam in kg/h which the boiler can create ‘from and at 100°C’,at atmospheric pressure. Each kilogram of steam would then have received 2 257 kJ of heat from the boiler.
boiler capacity - 15000 lb.hr x 2 Devided by 10 x 4.54 = water capacity of 13620litres you keep processing new water to steam, and 15000 kg/h of steam requires 15000 kg/h of new water (plus additional to offset any steam losses along the way) 15000 kg of water is about 15000 L (true at 4 °C, reasonable approximation from 1 - 20 °C)
