Summary:Abstract The potential for achieving ultra-low NOx levels (below 3 ppmv) in a gas turbine combustor via catalytic combustion has been recognized for more than 20 years [1]. However, the challenging environment in the combustor has until recently thwarted efforts to develop catalysts for this application. Development of the technology described below began 10 years ago with a recognition of the fundamental characteristics of Nx production in high-temperature environments and an analysis of approaches to catalytic combustion that were tried unsuccessfully in other laboratories. Starting from these early assessments, Catalytica devised and developed a new approach that has resulted in successful application of catalytic combustion to an operating gas turbine. The essential features of that technology and recent experiences in its application are the subject of this paper.
