Abstract
A combustor dome assembly includes an annular support plate fixedly joined to a combustion liner which confines combustion gases. The support plate includes a plurality of circumferentially spaced support openings for supporting respective carburetors, and respective splashplates fixedly joined coaxially to each of the support openings. Each of the splashplates includes an intermediate flared portion spaced axially downstream from an intermediate portion of the support plate to define a plenum, and a distal end spaced radially away from the liner to define a circumferential extending outlet gap in flow communication with the plenum. The support plate intermediate portion has a plurality of impingement holes disposed between the support openings and a proximal end of the support plate for channeling a first portion of compressed air as impingement air into the plenum to impinge against the splashplate intermediate portion. A plurality of circumferentially spaced air slots are disposed between the support plate proximal end and the liner for channeling a second portion of the compressed air therethrough and into the plenum for mixing with spent impingement air to form a cooling air film extending from the outlet gap along the liner for film cooling thereof.
