How To Calculate Boiler Efficiency


Performance of Boiler: Efficiency, Power, Heat Losses

If the boiler contains an economiser & superheater is considered a single unit, then the efficiency is termed as the overall efficiency of the boiler. Boiler Power . The American Society of Mechanical Engineers (ASME) has recommended that one boiler horsepower is equivalent to evaporation of 15653 kg of water per hour from and at 100° C.
