Coal-Fired Power Plant Heat Rate Reductions
2015-8-14 · The average, annual operating heat rate of U.S. coal-fired power plants is approximately 10,400 Btu/kWh. The design heat rate of a facility is based on full-load operation with no boiler blowdown, whereas most reported heat rates of operating facilities include performance during off-peak loads and include boiler blowdown.

2014-9-25 · Steam is formed above the reactor core or in separate pressure vessels, which then drives the turbine to produce electricity. The steam from this process is condensed and the water is reused. Below is a diagram of nuclear power generation. Unlike fossil fuel plants, nuclear power plants don't produce smoke (like coal-fired energy production).

Gas vs Coal Global Greenhouse Warming
2020-7-6 · Gas vs Coal. The CO2 emissions from Natural Gas Combined Cycle (NGCC) plants are reduced relative to those produced by burning coal given the same power output because of the higher heat content of natural gas, the lower carbon intensity of gas relative to coal, and the higher overall efficiency of the NGCC plant relative to a coal-fired plant (1).
