Answer #1

Typical efficiency of only coal based thermal power plant is around 35% to 37%.

If coal extraction, processing are also considered along with power plant efficiency then efficiency from extraction to electricity generation is around 23% extraction efficient is around 73%, processing is around 97%, transportation efficiency is around 95%. Hence, (0.73) () () ()

    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...
