Exergy Analysis and Efficiency Improvement of a Coal …
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.

Smokestack
A smokestack, stack, or chimney is a tall vertical pipe or channel used by power plants to exhaust combustion gases into the air. This height disperses pollutants over a wider area in order to minimize their impact. These gases are called flue gas, and are emitted when hydrocarbon based fuels such as coal, oil or natural gas are burned.. These flue gases …
