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. The mixture is burned at temperatures of more than 2000 degrees F.
Oct 04, 2009· Fossil fuelled power plants may also use a steam turbine generator or in the case of natural gas fired plants may use a combustion turbine. A coalfired power station produces electricity by burning coal to generate steam, and has the sideeffect of producing a large amount of carbon dioxide, which is released from burning coal and contributes to global warming.
