The inital combustor development of a pre-mix lean burn arrangement for an aero-derivative gas generator is described. The emission targets of the practical system were for the NOx and CO to be less than 25 vppm (15% O2) over a wide range of powers and ambient temperatures. From combustion rig testing of a two stage (in series) system at 1,5 and 20 atmospheres the baseload engine emissions are predicted to be NOx = 17 vppm (15% O2) and CO = 5 vppm with a turn down of 30% power. To achieve a wider power turn down a three stage (in series) system is required.
