How does coal gasification with CO2 separation work?
First the coal is transformed into a combustible gas using a transverse draft carburetor. The gas, which is under pressure, is then freed of dust and—what is decisive when it comes to protecting the environment—CO2. What remains is elementary hydrogen, which is burned off in a gas turbine. The gas turbine drives a generator that produces electricity. The hot exhaust gases are made of pure water vapor and are thus free of CO2. They are used in a steam turbine to drive a second generator which produces electricity. Power is thus produced by combining gas and steam turbines in an extremely efficient manner, which explains why this power plant concept is also referred to as a combined power station.
