Dry low NO sub x hydrocarbon combustion apparatus

Patent ·
OSTI ID:5042235
this paper describes gas turbine apparatus for dry low NO{sub x} combustion. It comprises: a first gas turbine set including a first compressor means for compressing incoming air to about 20 atmospheres, a first combustor having fuel injector means and being coupled to the first compressor means, and first turbine means coupled to the output of the first combustor for cooling the hot combustion products below a temperature at which ignition and thermal NO{sub x} occur; and a second gas turbine set including a second compressor means for compressing incoming air to about 10 atmospheres, a mixer coupled to the second compressor means for receiving air from the second compressor means, the output pressure of the first turbine means being about 5% higher than the output of the second compressor, so that rapid and homogeneous mixing in the mixer is assured, a second combustor having fuel injector means coupled to the output of the mixer, and second turbine means coupled to the output of the second combustor.
