Abstract

Gas turbine and steam power generating station with an integrated coal gasification plant which is supplied with oxygen via an air decomposition plant, with a methanol synthesis plant connected to the coal gasification plant, with a steam generating station part connected to the exhaust heat boiler of the gas turbine, as well as with a nitrogen line leading from an air decomposition plant to the combustion chamber of the gas turbine. The coal gasifier for the hydrogenating coal gasification is connected to a hydrogen supply line; the coal gasifier is followed, for utilizing the residual coke, by an iron bath gasifier, which is followed on the exhaust gas side by a converting plant and a carbon dioxide scrubbing plant connected to the hydrogen supply line. The exhaust gas line of the coal gasifier is connected via a gas purifier to a methanol synthesis plant and the exhaust gas line of the methanol synthesis plant is connected to the combustion chamber of the gas turbine.
