A steam generating plant consisting of a boiler, an economizer and super heater generates superheated steam at the rate of 50 tons per hr. feedwater enters the boiler at 5 MPa and 120 °C. Steam leaves the superheater at 4.5 MPa and 320 °C. if the coal used has a heating value of 30,000 kJ/kg, calculate the no. of tons of coal fired per hr for
