B[20M]/ Boiler generates 2400 kg of dry steam per hour at a pressure of 11 bar. The grate area of the coal is 3 m² and 90 kg of coal is burnt per m² of grate area per hour. The calorific value of the coal is 33180 kj/kg, and the temperature of feed water is 17.5 oC. Determine (1) actual evaporation per kg of coal. (2) equivalent evaporation. (3) efficiency of the boiler. US (01.2
