Abstract

PURPOSE: To accomplish significant reduction of NOx in a lean combustion method with a number of subcombustion chambers arranged by lessening the size thereof.
CONSTITUTION: Air 4 from a compressor passes between an outer cylinder 5 and a liner 6 of the combustion apparatus and fed to a subcombustion chamber 2 in the primary air current through an air inflow port 7, and the secondary air current 10 is fed to the main combustion chamber 3 through an air inflow port 9. Then, a diluted air 12 is introduced to the air current through a dilution port 11 while the combustion gas 13 is inducted to a turbine 7 through a transition piece 14. Fuel 16 is evenly delivered to each combustion device 1 with a flow divider 17, where it is distributed to respective fuel nozzles 15 mounted to a plurality of subcombustion chambers 2. An electromagnetic control valve 19 is provided in the fuel supply passage 18 interposed. With such an arrangement, the subcombustion chamber 2 functions to control the generation of NOx to ensure a constant lean combustion while the electromagnetic control valve 19 is opened ro closed so as to maintain a stable state of combustion.
