ABSTRACT:
The combination of a burner and a gas turbine in which the burner is divided into a combustion zone and a dilution zone. Means are provided to vary the fuel-to-air ratio within the combustion zone by diverting air directly to the dilution zone to produce exhaust gases for driving the turbine which have a relatively low content of nitrogen oxides, carbon monoxide and unburned hydrocarbons.
