Learn MoreTherefore the specific enthalpy of water at 0 bar g and 100°C is 419 kJ /kg, as shown in the steam tables (see Table 2.2.2). Another 2 257 kJ of energy are required to evaporate 1 kg of water at 100°C into 1 kg of steam at 100°C.

Learn MoreBoiler Horsepower What is the boiler horsepower of a boiler generating 21,500 lbs of steam per hour at 155 psi? The factor of evaporation is 1.08.

Learn MoreIn the United States, boilers are rated by boiler horsepower, with 1 hp being equal to 9.81 kW or the evaporation of 15.65 kg of water per hour at standard atmospheric pressure 101.4 kPa and 100°C. Every steam or water boiler is rated for a maximum working pressure according to its applicable boiler code.
