Abstract
A gas turbine combustor improves the fuel distribution from a main fuel nozzle, suppressing fluctuations of internal pressure and elevation of inner tube metal temperature, and enhancing the combustion stability and durability of the combustor. The gas turbine combustor is a multi-nozzle type premixing combustor with a nozzle outer tube ( ) for forming and injecting a premixed gas of main fuel and combustion air divided and disposed in plural sections around a cone ( ) for forming a diffusion flame by reaction between pilot fuel and combustion air disposed in a center of a section of a combustor inner tube ( ). Nozzle holes ( ) of a main fuel nozzle ( ) are formed in three positions at equal intervals on the nozzle main body wall, and one of them is disposed at the outer periphery of the combustor inner tube ( ) on a diametral line linking between the center of the combustor inner tube ( ) and the center of the main fuel nozzle ( ), whereby the fuel distribution to the outer periphery is decreased.
