2020/5/12 · 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.

Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow
Read More(1) Determine the mass flow rate in the cycle Assume the mass flow rate in the cycle is, then the mass flow rate of steam extracted from the turbine to the heat exchanger is and the mass flow rate of steam through the condenser is, where y is the fraction of steam extracted to the heat exchanger per kg of mass flowing through the boiler.
