Title: Gas and steam turbine contg. power station - includes plant for eliminating sulphur cpds in flue gases
Inventor: STAEGE HERMANN
IPC: F01K23/06
Filed: 1973-09-08
Abstract: The fuels used in the power station such as coal and oil are gasified before the fuel is used for combustion in the turbines etc. The gas is obtained from dried and finely powdered coal on using oxygen or oxygen rich gas and steam under a high pressure. This gas is cooled subsequently in a waste heat boiler and the steam from this boiler is used in a steam turbine for generating electricity. The gas is subsequently cooled further down by injection of water and cleaned in the contact plant so that sulphur bearing gas components are scrubbed out. This desulphurised gas is burnt with preheated air and the combustion gases are used in another boiler whose steam is once again used in steam turbine for generating electricity. The flue gases are passed through a gas turbine which operates a power generator and an air compressor. Exhaust gases from the gas turbine are used for drying of coal.
