How Gas Turbine Power Plants Work Department of EnergyGenerating Electricity from Coal Duke Energy

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 airIn a coal fired steam station much like a nuclear station water is turned into steam which in turn drives turbine generators to produce electricity Here’s how the process works 1 Heat is created Before the coal is burned it is pulverized to the fineness of talcum powder
