COMBUSTION LINER COOLING

The present disclosure is directed to a combustor (16) including an annularly shaped liner (42) that at least partially defines a hot gas path of the combustor (16) and a flow sleeve (54) that circumferentially surrounds at least a portion of the liner (42). The flow sleeve (54) is radially spaced f...

Zusammenfassung:	The present disclosure is directed to a combustor (16) including an annularly shaped liner (42) that at least partially defines a hot gas path of the combustor (16) and a flow sleeve (54) that circumferentially surrounds at least a portion of the liner (42). The flow sleeve (54) is radially spaced from the liner (42) to form a cooling flow annulus (56) therebetween. A plurality of fuel injector assemblies (102) circumferentially spaced about the flow sleeve (54) and each fuel injector assembly (102) extends radially through the flow sleeve (54), the cooling flow annulus (56) and the liner (42). A first portion (60) of the flow sleeve (54) defined between a first pair of circumferentially adjacent fuel injector assemblies (102) of the plurality of fuel injector assemblies (102) bulges radially outwardly with respect to an outer surface (62) of the liner (42) so as to enlarge a flow volume of the cooling flow annulus (56).
