A high efficiency gas turbine engine is described, having compression means, combustion means, turbine means, and means for reducing nitrous oxide emissions from an exhaust gas stream exiting from the turbine means, the engine further comprising: interchanged means in fluid communication with a hot compressed air stream exiting from the compressor means, for cooling the compressed air stream as it passes there through; 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 separably passable there through, the fuel heated by the hot compressed air stream prior to entering the combustion means and, premixer means for reducing the nitrous oxide emissions, the heated fuel entering the premixer means and mixed with water prior to entering the combustion means, the entering fuel being at a temperature which vaporizes the water and prevents condensation of the resultant stream during injection into the engine.
