The design and initial rig testing of an ultra-low NOx gas-turbine combustor primary zone are described. A lean premixed, swirl-stabilized combustor was evaluated over a range of pressures up to 13.2 x 10/sup 5/ Pa (13 atm) in a test-rig environment using natural gas. The program goal of reducing NOx emissions to 10 ppm (at 15% O/sub 2/, dry) with coincident low CO and unburned hydrocarbon emissions was achieved at all combustor pressure levels. Appropriate combustor loading for ultra-low NOx operation was determined through emissions sampling within the primary zone. The work described represents a first step in developing an advanced gas-turbine combustion system that can yield ultra-low NOx levels without the need for water injection and selective catalytic reduction. To advance the technological readiness of the lean premixed burner concept, additional effort is required in the areas of dilution zone development, combustor operating-range extension, and combustion-system controls.
