A 150-MW, 1300°C (1573 K) class gas turbine combustor firing coal-gasified fuel has been designed. Main purpose of this paper is to estimate CO and NOx emissions, and to discuss the low NOx combustion technology burning such a low-BTU gas. The full-scale, atmospheric-pressure combustion tests were conducted over a wide range of conditions using bypass air. The role of air bypass valve is important for low NOx combustion, and to give stable combustion at lower load conditions. Ammonia conversion to NOx is minimized with a optimum air ratio in primary combustion zone.
