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 major method for CO 2 capture from fossilfuel power plants is postcombustion capture, where the CO 2 is separated from the flue gas after combustion. The advantage of postcombustion is that it is easy to implement into existing coalfired power plants [3 ]. Currently, amine absorption process seems to be the most mature technology for CO 2 ...
