Point source capture (PSC) in fossil fuelbased power production separates CO 2 emissions from a power plant's flue gas or syngas stream to prevent its release into the atmosphere. The captured CO 2 is durably stored or converted to a longlived product, resulting in an overall reduction in CO 2 emissions. In conventional fossil fuelfired power plants, a fossil fuel such as natural gas is ...

The purpose of the coal stockyard is to ensure that there is sufficient coal reserves available to keep the power station in operation should the mine experience production problems. Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas.

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.
