More. 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.

The 300 MW Elcogas plant uses a mixture of 50% wt. subbituminous high-ash coal and 50% petroleum coke from a nearby oil refinery. Coal is ground to < 50-60 m in two roller mills.
Depending on these three primary inputs there are three basic flow circuits that work on a thermal power generating plant. Coal Circuit. The coal is transported from coal supplying authorities to the coal storage yard of the generating plant. From here the coal is delivered to the pulverized coal plants with the help of a conveyor.
Entire plants are dedicated to servicing power plants. If we're talking about emissions from a furnace, such as a coal-fired power plant, it's similar to the pre-smelting stage in metallurgy. Cyclones and bag filters are commonly used, or cyclones with electrostatic filters or scrubbers (although the latter is a rare occurrence).
A major method for CO 2 capture from fossil-fuel power plants is post-combustion capture, where the CO 2 is separated from the flue gas after combustion.
