A low-NOx combustor is provided with a rich, primary burn zone and a lean, secondary burn zone. NOx formation is inhibited in the rich burn zone by an oxygen deficiency and in the lean burn zone by a low combustion reaction temperature.


A low-NOx combustor for heating compressor discharge gases to drive a turbine, comprising: a basket having a wall for containing combustion therein and further having an upstream zone for fuel rich, diffusion flame combustion and a downstream zone for fuel-lean combustion with a necked-down quench zone connecting said cumbustion zones; means for injecting fuel into the upstream end of said basket; means for enabling fuel-rich combustion of the fuel injected by said injecting means in said fuel-rich combustion zone; means for introducing a quench air flow...
