BURNER COOLING STRUCTURES

Abstract:

A burner includes a main body having an outer surface and at least partially defining an interior. The main body further includes an upstream end axially spaced from a downstream end. The outer surface includes a burner front face at the downstream end of the main body. An annular cooling air plenum is defined in the main body radially inwardly from the outer surface. A cooling air passage extends from the outer surface to the annular cooling air plenum. A plurality of cooling channels is circumferentially spaced apart from one another along the burner front face. Each cooling channel of the plurality of cooling channels extends from a respective inlet in fluid communication with the annular cooling air plenum to a respective outlet.
