Example (2): a 5400 kg/hr of steam is supplied by a certain boiler plant at pressure (750 kPa) and dryness fraction 0.98. Feed water is supplied at a temp. (41.5°C). The mass of fuel (coal) is (670 kg/hr) with L.C.V = 31000 kJ/kg. Determine: a) The boiler efficiency. b) The equivalent evaporation E.E. at 100°C. c) The saving in coal per hour if the economizer is fitted in the flue gases (the feed water temp. can be raised to 100°C), assuming the other conditions are the same.
