COMBUSTOR FOR GAS TURBINE |
摘要 |
A gas turbine combustor has an inner cylinder provided with a multiplicity of louvers for introducing cooling air and a plurality of air ports for introducing combustion air. The portions of the inner cylinder wall at both ends of each louver, where the concentration of stress due to thermal stress is heaviest, is reinforced by build-up welding thereby to prevent cracking at these portions of the cylinder wall. The build-up welding effectively stops the propagation of crack happened to be caused in the inner cylinder wall for any reason. The portions of the inner cylinder wall around the air ports also may be reinforced by build-up welding over the entire peripheries of these air ports. The build-up weld on the periphery of each air port prevents any crack from being propagated to the brim of each air port. |
