In a boiler, 525 Kg/hr of coal is used to produce 5200 Kg/hr of steam at a pressure of 15 bar and temperature of 250° C. The feed water temperature is 27° C and the CV of fuel is 30000 KJ/ Kg. Assuming Cp of water = 4.2KJ/KgK and Cp of steam 2.1 KJ/KgK, calculate: (1) Equivalent evaporation (2) Boiler efficiency (3) Boiler power. At 15 bar pressure, specific enthalpy of steam (gas) is 2789.9 KJ/Kg and saturation temperature of steam is 198.3° C.
