Abstract

Method and apparatus for control of Zeldovich (thermal) NOx production in catalytic combustion systems during combustion of liquid or gaseous fuels in the post catalytic sections (14) of gas-turbine combustors by reducing combustion residence time in the Homogeneous Combustion (HC) zone through control of the HC Wave position, principally by adjusting the catalyst (13) inlet temperature. As the fuel/air mixture inlet temperature to the catalyst is reduced, the HC Wave moves downstream, extends the ignition delay, shortens the residence time at high temperature, thereby reducing the thermal Nox production. The countervailing increase in CO production by longer ignition delay can be limited by actively positioning the HC Wave so that thermal Nox is reduced while power output and low CO is maintained. Nox is reduced to on the order of <3ppm, and preferably <2ppm, while CO is maintained <100ppm, typically <50ppm, and preferably <5-10ppm.
