In the process, the excess air coefficient in the combustion area is transited from rich combustion to lean combustion, and meanwhile, the combustion temperature in the core area is in a reasonable range, so that the purpose of reducing pollutant emission while stabilizing combustion is achieved, and the low emission state can be kept in a wider working condition range.

During the process of adjusting the air flow and the fuel flow under the low working condition or the high working condition, the variation gradient of the fuel quantity and the air quantity can be controlled through the determined inverted T-shaped groove rail installation angle alpha. The invention not only solves the problems of large air flow, unstable combustion and low operation efficiency of the gas turbine under the condition of low working condition, but also widens the operation range of realizing low emission under the condition of high working condition. Especially for single-shaft gas turbines used for power generation, has important practical value.
