초록

During low-load operating conditions, preburner combustion products are supplied with a chemical reactant to reduce NOx. The preburner products of combustion are mixed with a hydrocarbon fuel in the presence of a combustion catalyst to ignite and initiate a catalytic combustion reaction. The preburner is then shut down. The fuel/air mixture supplied the catalytic reactor bed during the mid-load operating range of the turbine is sufficiently lean to produce a combustion reaction temperature too low to produce thermal NOx. Thus, at low-load conditions, pre...
