摘要： The invention relates to a turboshaft engine comprising a heat converter in combination with at least one catalytic converter. A first heat exchanger (133) is adapted to decrease the temperature to the operating temperature of the at least one catalytic converter (141,142). The catalysts may reduce carbon monoxide, hydrocarbons by oxidation and nitrogen oxides by selective catalytic reduction. Furthermore a second heat exchanger (134) is provided in order to transfer the heat extracted from the hot exhaust gas by the first heat exchanger (133) to the entrance of the combustion section (120). This heating of the compressed air just before the combustion improves the combustion efficiency of the engine thus carbon dioxide emissions can be reduced. Finally the exhaust temperature reduction leads to a reduced Infrared signature of the turboshaft driven aircraft in particular of helicopters.

摘要： The invention relates to gas tubine engines, especially a turbojet or turbofan for an aircraft. The gas turbine engine comprising a combustion section and an exhaust section produces an exhaust gas. The emission products can be reduced by usig a gas treatment device with a reactor and an injection device. The reactor produces a nitrogeneous substance such as ammonia. This reducing agent is injected in the gas phase in the exhaust section of the gas turbine engine. By selective non catalytic reaction the Nitrogen oxides of the exhaust gas can be reduced. Furthermore the injection device is arranged such that the temperature window of this reduction process is ranging from 850°C to 1100 °C. The reactor for producing gaseous ammonia can either be a thermal reactor or a high pressure plasma device.
