Abstract: A method of operating a gas turbine power plant comprising of a first gas turbine group, consisting of a compressor and a turbine which are connected mechanically with one another, and a second gas turbine group, including a combustion device, which is placed in the gas flow stream between the first group's compressor and turbine, whereby the second gas turbine group consists of a compressor, a fuel injection device, a combustion chamber and a turbine, whereby the second gas turbine group's compressor and turbine are mechanically coupled to one another and at least one of the gas turbine groups having a device for the extraction of work, whereby the fact that a first flow of water and/or steam is heated with heat from the flue gas from the first group's turbine, that further amounts of water and/or steam are heated with heat from a gas stream that is compressed by the first group's compressor, and the produced water and/or steam is injected into the gas stream in such amounts that at least 60% of the oxygen c

Abstract: A device and a method to extract mechanical energy in combination with heat and/or coiling from a combustion engine, to which fuel and air is fed, whereby water is added to the combustion engine's inlet air prior to combustion. The combustion engine's flue gas is fed at above-atmospheric pressure to the fist stage of a flue gas condenser, from which heat is extracted and utilized by a heat consumer and/or a sorption cycle. After condensation, the water-lean flue gas is reheated in order to avoid ice formation during the final expansion.
