Question

A boiler generates 13000 kg of steam at 7 bars during a period of 24 hrs and consume 1250 kg of coal whose CV. = 30000 kJ/kg. Taking the enthalpy of steam coming out of boiler = 2507.7 kJ/kg and water is supplied to the boiler at 40°C. Find: (a) efficiency of the boiler b) Equivalent evaporation per kg of coal.​
