PROBLEM TO BE SOLVED: To cool a cap plate.SOLUTION: A combustor cap assembly (100) includes a flow conditioning plate (102) coupled to a forward end portion (114) of a shroud (104). The flow conditioning plate (102) includes an inner band portion (152), an outer band portion (154), and an annular portion (156). The annular portion (156) defines a plurality of flow conditioning passages (162). The inner band portion (152) at least partially defines a cooling air plenum (110) within the combustor cap assembly (100). The inner band portion (152) defines an exhaust channel (166) which is in fluid communication with an impingement air plenum (146) and an exhaust outlet (168). The flow conditioning plate (102) further defines a cooling air passage (176) which enables a cooling air flow to enter the cooling air plenum (110).SELECTED DRAWING: Figure 3 |
