A coal-fired steam power plant produces 175 MW of electric power. The power plant operates on a Rankine cycle with turbine inlet conditions of 7 MPa and 550oC and a condenser pressure of 15 kPa. The turbine efficiency and pump efficiency are both 0.8. The coal has a heating value (energy released when the fuel is burned) of 29,300 kJ/kg. Assuming that 85 percent of this energy is transferred to the steam in the boiler and that the electric generator...

A typical large coal fired electric power plant produces 1,200MW of electricity by burning fuel with energy content of 3,000 MW. Three hundred and forty (340) MW are lost as heat up the smokestack leaving the rest to drive a generator to produce electricity. However, the thermal efficiency of the turbine is only 45%. That is 45% of the remaining power goes to drive the generator, and 55% is waste heat that must be removed by cooling water. Assume that...
