PURPOSE:To reduce the generation of NOx by a method wherein fuel is supplied to an inner tube, which is arranged within a combustor liner near its upstream end. CONSTITUTION:An inner tube 2 provided with openings 4 on the wall of the tube is fied within a cylindrical combustor liner 1 provided with air intake openings 10 on the wall of the liner near the upstream end of the liner in order to supply fuel in the interior of the inner tube 2. In addition, secondary fuel supply nozzles 19 and an air lead-in means are provided near an expanded portion formed by expanding the combustor liner 1 near its downstream. Consequently, a gas turbine combustor, in which the reduction of NOx due to premix effect can be realized, stable combustion can be performed with no fear of back firing, and yet pressure loss is scarce, is obtained. |
