This patent describes a high efficient gas turbine engine, having compression means, combustion means, turbine means, and means for reducing nitrous oxide emission from an exhaust gas stream exiting from the turbine means. It comprises interchange means in fluid communication with a hot compressed air stream exiting from the compressor means, for cooling the compressed air stream as it passes therethrough; means for delivering the cooled compressed air stream to the turbine means for cooling the turbine means, a fuel, in fluid communication with the interchange means, and separability passable therethrough, the fuel heated by the hot compressed air stream prior to entering the combustion means and, pre-mixer means for reducing the nitrous oxide emissions, the heated fuel entering the pre-mixer means and mixed with steam prior to entering the combustion means, the entering fuel being at a temperature which prevents condensation of the steam during mixing.
