WhatsApp: +86 18838072829Flue gases, bottom ash, and fly ash formed during fuel combustion are examples of pollution occurring from the combustion process. Land use of the power plant, coal mining and transport, and feeding of the coal to the combustion chambers can also cause pollution. The cooling water is another pollution source to the surrounding water systems.
WhatsApp: +86 18838072829How 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 ...
