Catalytic combustion system for a 10 MW class power generation gas turbine

Abstract In early 2000, GE Energy launched a program to develop a catalytic combustion system for one of its small power generation gas turbines, the GE10-1 engine. The target was to release to the market a new combustor able to guarantee NO x emissions lower than 2.5 ppmvd (referred to 15 vol.% O 2 ). Today, a full-scale engine test campaign has been completed, during which measured NO x emissions were as low as 1 ppmvd in the 90–100% load range. The article is aimed to illustrate the developed technology and the results obtained. The combustion system's configuration is briefly described, focusing on the XONON ® catalyst module installed. Reported data show combustion system's performances, mainly in terms of pollutant emissions and operability. Perspectives for future development of such combustion system are outlined.
