A cyclic steam power plant is designed to supply steam from the boiler at 10 MPa and 550 °C when the boiler is supplied with feed water at a temperature of 210 °C. It is estimated that the thermal efficiency of the cycle will be 38.4% when the net power output is 100MW. Calculate the steam consumption rate (m,). The enthalpy of the feed water may be taken as being equal to the enthalpy of saturated water at the same temperature. The boiler efficiency is 87% and the HHV of the fuel is 42500 kJ/kg. Calculate the rate of fuel consumption in kg/s (m,) and ton/min.
