Abstract

PURPOSE: To reduce the generation of NOx by a mechanism wherein a plurality of fuel nozzles are provided on a plurality of circumferences of different radius but of concentric circles respectively, and the nozzle tips of the inner cirles are protruded into the inside of the combustion chamber longer than those nozzle tips of the other circles.
CONSTITUTION: The primary fuel nozzles 41 are provided on the outer circumference while the secondary fuel nozzles 42 are provided on the inner circumference respectively, and the nozzles 42 are protruded into the inside longer than the nozzle 41. On each of the nozzles, air spinner 61 acting as the primary air 101 feeder is established respectively, and at the center of the combustion chamber, the central air spinner 7 which protrudes longer than the nozzles 42 is provided. Air 101A for primary combustion is induced from those three parts as the spinner 61, outside diameter and inside diameter sides of the combustion liner 2, mixes with the primary fuel 201, and inducing excess air, performs lean mixture combustion adequate for entire range of operation. At the same time, air 101B for secondary combustion mixes with the secondary fuel 202 and the generation of NOx is restricted at a low level.
