PURPOSE:To contrive the reduction of a pressure loss as well as the increase of a combustion efficiency and elongate the life of a catalyst by a method wherein the diameter of a linear for the combustor, having air holes for supplying pre- mixture, is made larger than the same of parts before and after the combustor. CONSTITUTION:Pilot fuel, supplied from a fuel nozzle 101, is burnt by the air entering through the air holes 102. On the other hand, the fuel, supplied from the fuel nozzles 103 is mixed with the air entering through the air holes 104, thereafter, flows through the combustion catalyst 105 and is burnt. Then, combustion gas flows into a turbine (not shown in the diagram) through a tail tube 106. Here, the diameter of the linear for the combustor, provided with the air holes 104, is made larger than the diameters of the parts before and after the combustor. According to this method, the diameter Dc of the core of air jet may be enlarged since the number of the air holes, provided on the linear, may be increased and the diameter Do of the linear is enlarged. Accordingly, the pre- mixture may be flowed through the catalyst uniformly. |
