Steam boiler plant provides power to the surrounding area. An economiser, evaporator, and superheater make up the steam boiler plant. Fuel energy will be required to heat feed water to supply power generation in the mining and residential areas. At 9 bar, the boiler produces wet steam (4 900 kg/hr) from source water at 48°C with a dryness fraction of 0.89. If 490 kg of coal with a 42 MJ/kg calorific value is used, calculate: 5.1 The thermal efficiency of the boiler. 5.2 The equivalent evaporation.
