Abstract
Provided is a combustor that is made compact and achieves NOx reduction. In the combustor () including a pilot nozzle () disposed along the central axis of the combustor () and performing diffusion combustion, a plurality of main nozzles () disposed on the outer peripheral side of the pilot nozzle () at intervals in the circumferential direction and performing premixing combustion, a single inner cylinder () surrounding the pilot nozzle () and the main nozzles (), and an outer cylinder approximately coaxially surrounding the outer side of the inner cylinder () to form a compressed air passage () between the inner peripheral surface thereof and the outer peripheral surface of the inner cylinder and turning the flow direction of compressed air flowing in the compressed air passage () in approximately the opposite direction at the end of the inner cylinder () to introduce the compressed air into the pilot nozzle (), the compressed air passage () is provided with a flow rate controller that makes the flow rate on the combustor () inner peripheral side of the passage larger than that on the outer peripheral side. An example as the flow rate controller is a baffle plateprovided with holes
