Title:
COMBUSTION LINER COOLING
Document Type and Number:
Japanese Patent JP2017166483
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce influence of axially staged injectors that extend through a flow sleeve, a cooling flow annulus and a liner.SOLUTION: The present disclosure is directed to a combustor 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. The flow sleeve 54 is radially separated from the liner to form a cooling flow annulus therebetween. A plurality of fuel injector assemblies 102 are spaced about the flow sleeve circumferentially and each fuel injector assembly extends radially through the flow sleeve, the cooling flow annulus and the liner. A first portion 60 of the flow sleeve defined between a first pair of circumferentially adjacent fuel injector assemblies of the plurality of fuel injector assemblies bulges radially outwardly with respect to an outer surface of the liner so as to enlarge a flow volume of the cooling flow annulus.SELECTED DRAWING: Figure 2
