Abstract
A gas turbine combustor has homogenous air inflow by elimination of turbulence from the air, reducing combustion instability. A combustor has, at its center, a pilot nozzle and eight main nozzles around the pilot nozzle . The air flows in around the individual nozzles and to the leading end of the combustor so that it is used for combustion. An annular flow ring , having a semicirculat section, is disposed at the upstream end portion of a combustion cylinder , and a porous plate and a surrounding rib are disposed downstream of the flow ring . The air inflow is smoothly turned at first by the flow ring and then straightened by the porous plate so that the air flows without any disturbance around the individual nozzles and to the leading end, thereby reducing combustion instability.
