How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...

A coalfired power station is a type of fossil fuel power station. The coal is usually pulverized and then burned in a pulverized coalfired boiler. The furnace heat converts boiler water to steam, which is then used to spin turbines that turn generators.

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.

Today, the entire coal industry—including mines and power plants—employs roughly 160,000 people. For scale, the solar industry provides 374,000 jobs in the US, with most of those people—261,000—working on solar at least half time. If you're a coal miner, or live in a mining community, the transition has been hard.

The generation of electricity begins at the power plant— where fuel sources such as coal, natural gas or hydro are used to transform water to steam by a heating process. For example, in most coal fired power plants, chunks of coal are crushed into fine powder and are fed into a combustion unit where it is burned.
