Developments in catalytic combustion have shown increasing potential for application in gas turbine combustors. Significant advantages in reducing combustor emissions, particularly nitrogen oxides (NOx), can be realized. Both thermal and fuel NOx control were demonstrated for a developed graded cell catalyst concept. Other criteria for catalyst scaleup and high pressure operation have been developed. The concepts have been demonstrated in a catalytic model gas turbine combustor and a catalytic staged combustor. The staged combustor shows great potential for control of fuel NOx. New concepts in turbine combustors are required to implement catalytic combustion technology. Gas turbine manufacturers were surveyed to identify design criteria. The established criteria were prioritized and incorporated into several conceptual designs for the combustor. Ongoing development will advance the concepts to prototype demonstration.
