PDF Performance of coalbased thermal power plant at full load and part loads

Most of the coalfired power plants have efficiencies less than 35% by using indigenous high ash coal. Now a day, efforts are taking place to bring in highly efficient super critical technology in the country for thermal power plants. Energy analysis of coalfired power plant is done using mass and energy balance equation [2].
