How Does Clean Coal Work? - Popular Mechanics

Coal plants today typically use what is called pulverized coal. That means the coal is ground up, burned, and the steam from that burning drives turbines. There's also newer

How Does an Oil Power Plant Work? | Sciencing

Power plants that burn oil to produce electricity are called oil-fired plants. They are no different in general principle and operation from their fossil-fueled cousins, the coal-fired and natural gas-fired plants, and are even similar to geothermal and nuclear power plants in some respects.

How do coal-fired power plant scrubbers work? | …

Marshall Brain Answers: If coal were pure carbon, then the only thing we would have to worry about at coal-fired power plants is the carbon dioxide formed when coal burns.

How Gas Turbine Power Plants Work | Department of …

Home » How Gas Turbine Power Plants Work The compressor, which draws air into the engine, pressurizes it, and feeds it to the combustion chamber at speeds of hundreds of miles per hour. The combustion system, typically made up of a ring of fuel injectors that inject a steady stream of fuel into combustion chambers where it mixes with the air.
