As described previously in ASME papers, an effort has been underway to apply catalytic combustion for small gas turbines. To improve combustion efficiency at the engine operating conditions, two catalytic combustors have been developed. Both combustors showed high combustion efficiency and low NOx emissions in combustor rig tests. In engine tests, Type A combustor achieved the NOx goal of 15 ppmv as corrected to 5 percent oxygen (5.6 ppmv at 15 percent oxygen) for base load operation. Combustion efficiency was greater than 98 percent for the fresh catalyst, however, it decreased rapidly with catalyst deactivation.
