The authors have been developing a low emission, single can combustor for Niigata's 300kW class industrial radial gas turbine engine, RGT3R, to satisfy environmental requirements for the distributed power generation system. A lean premised, pre-vaporized combustion system is used to minimize emissions level to meet the environmental requirements. This combustion system is consists of two pilot burners and two main burners. Each burner has double concentric axial swirlers to prevent flash back into premixing tubes and combustion driven pressure oscillations. Main burners are axial-staged from stable pilot burners flame. The emissions goal is less than 20 ppm nitrogen oxides (NOx), 50 ppm carbon monoxide (CO) and unburned hydrocarbons (UHC's) at dry 16% O2 correction, while operating over 50% load conditions. This paper describes CFD analysis, component and combustion rig testing results.
