Coal-fired power station - Wikipedia
A coal-fired power station is a type of fossil fuel power station.The coal is usually pulverized and then burned in a furnace with a boiler.The furnace heat converts boiler water to steam, which is then used to spin turbines which turn generators.Thus chemical energy stored in coal is converted successively into thermal energy, mechanical energy and, finally, electrical energy.

Types of Boiler Coal Pulverizers - Bright Hub Engineering
Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
