Abstract

PURPOSE:To reduce NOX generated by providing a hollow cylindrical member in the vicinity of the upstream of an inner cylinder at the head portion of a combustion chamber, igniting the fuel by the tip end of the cylindrical member and igniting a gaseous mixture introduced from a cylindrical gap between an inner cylinder and the hollow cylindrical member. CONSTITUTION:The gaseous mixture of the fuel injected from a nozzle 3 by an ignition plug 7 inserted into the vicinity of the fuel nozzle 3. With the rise of the combustion intensity, the fuel 29 is injected from a fuel header 14 and a pipe 16 into an annular hollow part 13, and is mixed with an air current 31 and is rotated and jet-streamed within a pre-mixing chamber 11. At the time of a high intensity combustion, further a fuel 32 is injected through a header 20 into an annular hollow part 23, and mixed with an air current 34 and introduced into a main combustion chamber 8 through an annular swirler 18. This gaseous mixture is ignited by a flame of the nozzle 3. By supplying to burn a premixed gas in two stages in correspondence to the load, the flame stability of the fuel nozzle can be improved and generation of NOX can be reduced.
