This type of coal fineness increases the surface area for burning. This leads to an increased combustion rate and shelf life of the coal. Pulverized coal is typically used in power plants heated in fired furnaces. 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.
