Exergy Analysis and Efficiency Improvement of a Coal Fired …
2. Process description of a coal-fired power plant. A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.
