Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.Learn More
boiler of this type, filled with water and ready for function, can weigh as much as 165 tons, which corresponds to the weight of 120 VW Golfs. Hot water or steam boilers …Learn More
Self Exercise 3 Gaseous propane of 88 kg/hr is burned in a boiler with 10% excess air to produce 1200 kg/hr of steam at 0.1 MPa and 150oC. The percent conversion of the propane is ; of the fuel burned, 90% reacts to form CO2 and the balance to form CO.Learn More
Boiler Capacity - Engineering ToolBoxLearn More
Boiler load - the capacity of a steam boiler - is often rated as boiler horse powers, lbs of steam delivered per hour, or BTU. Lbs Steam delivered per Hour Large boiler capacities are often given in lbs of steam evaporated per hour under specified steam conditions.Learn More

In order to get around these problems, the Rankine Cycle uses superheated steam from the boiler to the turbine. The condenser completely condenses the exhaust steam into saturated water. The compressor is replaced with a water (feed) pump to return The Learn More

However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building Learn More
