Consider a coal-fired steam power plant that produces 175 MW of electric power. The power plant operates on a simple ideal Rankine cycle with turbine inlet conditions of 8 MPa and 560°C and a condenser pressure of 8 kPa. The coal has a heating value (energy released when the coal is burned) of 29,300 kJ/kg and a CO2 emission value of 0.093 kg CO2/MJ. Assuming that 85% of this energy is transferred to heat in the boiler and that the...

A nuclear power plant has a reactor that produces heat at the rate of 870 MW. This heat is used to produce 240 MW of mechanical power to drive an electrical generator. (a) At what rate is heat discarded to the environment by this power plant? MW (b) What is the thermal efficiency of the plant? A research group plans to construct an engine that extracts energy from the ocean, using the fact that the water temperature near the surface...

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...
