This paper demonstrates the feasibility of a gas turbine combustor with multi hole co-axial jet burners for dry low NOx combustion of Coke Oven Gas (COG). The demonstration test used a hydrogen-rich gas containing 47% of hydrogen by volume as a test fuel of COG. The pressure inside the combustor was 0.6MPa. From the test results, the following conclusions are obtained: (1) The startup by ignition of a liquid fuel, the shift from the liquid fuel to the gaseous fuel operation, and the ignition of the gaseous fuel in the main burners at partial loads are successful. The combustor allows stable combustion from start-up to full load condition. (2) The NOx emissions decrease with the increase of fuel ratio of outer part in main burners.
