TVA - How a Coal Plant Works

Coal-fired 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.

High Efficiency Low Emission Coal | HELE | WCA

Deploying high efficiency, low emission (HELE) coal-fired power plants is a key first step along a pathway to near-zero emissions from coal with carbon capture, use and storage (CCUS). HELE technologies are commercially available now and, if deployed, can reduce greenhouse gas emissions from the entire power sector by around 20%.

Efficiency improvement of coal-fired power stations - EE

Coal-fired power stations (CFPS) are going to be around for many years to come. In addition to existing stations, new CFPS are being built at a steady rate. Much benefit can be gained from improving efficiency, such as using less coal per unit of energy, and emitting less CO 2 into the atmosphere. There are several international programmes aimed at improving efficiency of CFPS.
