A dual fuel dry low NOx Combustor for both LNG and heavy oil A was developed for Gas-To-Wire Power generation system. The dual fuel dry low NOx combustor employed lean premixed, pre-vaporized combustion system to meet stringent emission standards. In the initial phase of development, model burner experiments were performed to study combustion characteristics of lean premixed, pre-vaporized combustion system. In the phase two, combustion characteristics of full scale combustor was confirmed using high pressure combustion test rig. As a result, the basis of dry low NOx combustion technology for the combustor that was fueled LNG and heavy Oil A was established. NOx emission level was under 25ppmv(15%0_2) with LNG, 80ppmv(15%O_2) with heavy Oil A and combustion efficiency was over 99.9% at base Load condition.
