Abstract

PURPOSE: To improve the NOx reducing effect of a lean burning NOx combustor in a larger premixing degree with a fuel injection hole facing a tangential spiraling device.
CONSTITUTION: A fuel passes through fuel manifolds 13 from a fuel feed pipe 15 and injected from a fuel injection hole 12 to be premixed with air in a tangential spiraling device 7, which enables premixing with air up to about 15 times as large as the flow rate of the fuel. It is possible that the fuel manifolds 13 are mounted to both tangential spiraling devices 7 and 9 to separtely divide the fuel thereto. Therefore, in the case of a low load combustion, the fuel is fed only to the tangential spiraling device 7 to stabilize the flame with a reverse flow A in a subcombustion chamber 4. In the case of a high load combustion, the fuel is also fed to the tangential spiraling device 9 to be burned in a main combustor 3. Thus, especially in a gas turbine with a board action range, a stable lean burning is possible over the entire load range.
