Abstract:
A gas turbine construction having an air compressor, a heat exchanger connected downstream of the air compressor, a combustion chamber, and a turbine which can be driven by hot combustion gases and from which the combustion gases are fed to the heat exchanger for heating compressed supply air coming from the air compressor, wherein the heat exchanger and the combustion chamber are integrated in a common unit, and wherein fuel can be added to the supply air before entry in the unit, which fuel can be ignited catalytically in the form of an air/fuel mixture inside the unit, in which a catalyst is provided;the unit comprising of heat exchanger and combustion chamber provides at least one duct which feeds the air/fuel mixture to the turbine and is thermally coupled to at least one exhaust-gas return duct carrying off the combustion gases; andwherein the duct feeding the air/fuel mixture is provided, at least partly, with a catalyst material on the inside.
