##### Reference no: EM13341992

A typical coal-fired power plant burns 310 metric tons of coalevery hour to generate 780MW of electricity. 1metricton=1000kg. The density of coal is 1500 kg/m3 and its heat of combustion is 28 MJ/kg. Assume that all heat is transferred from the fuel to the boiler and thatall the work done in spinning the turbine is transformed into electrical energy.

What is the power plant's thermal efficiency?
