PURPOSE:To enable adaptation of a combustor to a high temperature gas turbine through decrease of a gas pressure loss and improvement of combustion efficiency, by a method wherein, in a combustor for gas turbine power generation, a region, in which partial reverse flow of combustion gas occurs, or a region, in which an average velocity of flow is partially delayed, are formed. CONSTITUTION:Structures 9, which form a reverse flow or a delay region, are located on the inner wall of a flow-out pipe 10 for combustion gas in a manner to act as a baffle board. This disturbs the smooth flow of combustion gas flowing out from a catalyst charge part 7, and a part of combustion gas, flowing along the inner wall of the flow-out pipe 10, flows to the inside of the structure 9 therearound to delay a reverse flow or an average velocity of flow. The formation of such region reduces a flame propagating speed, burns a unburnt fuel to form a flame, and improves the combustion efficiency of a gas phase at the down-stream of the catalyst charge part 7. This improves combustion efficiency through a decrease in a gas pressure loss, and enables adaptation of a combustor to a high temperature gas turbine. |
