摘要
In a gas turbine having a transition region between a combustor and turbine stage including a transition piece duct extending between a combustor liner and the turbine stage; an impingement sleeve surrounding the transition piece, the impingement sleeve having a plurality of apertures therein; and a compressor diffuser (28) directing compressor discharge air into the transition region, an improvement wherein the diffuser includes a pair of outer walls (30,32) flaring outwardly in a direction of compressor discharge air flow; and a pair of baffles (34,36) within a flow area defined by the pair of outer diffuser walls which divide the flow area into three discrete flow passages (54,56,58). One passage (54) has a substantially radial flow component; a second passage (56) has both radial and axial flow components; and a third passage (58) has a substantially axial flow component. IMAGE
