A steam turbine takes up steam at 1200 K and discharges the waste steam to the condenser at 450 K. In order to maintain the source temperature constant at 1200 K, coal is fired at the rate of 120 t h-1 in the boiler. Taking into account the losses in the boiler, 70% of the fuel heat goes to generate steam which is supplied to the turbine with a negligible heat loss. The turbine is coupled to a turbo-alternator to generate an AC. If the generator efficiency is 93% and transmission efficiency is 95%, what is the electrical power output available in the grid? Given the calorific value of fuel is 32000 kJ/kg.
