  • Gas Turbine Engine
    Publication number: 20090133380
    Abstract: A gas turbine engine is described having at least one compressor, at least one combustion chamber, at least one turbine, and having an exhaust heat exchanger, which is used for returning waste heat of the exhaust emissions to the compressed combustion air prior to entry of the same into a combustion chamber. The exhaust heat exchanger is used as a substrate for catalysts for use in the catalytic aftertreatment of the exhaust emissions, in order to thereby reduce the pollutant emissions, in particular NOx emissions, of the gas turbine engine.
