BURNER COOLING STRUCTURES

A burner (100) includes a main body (106) having an outer surface (112) and at least partially defining an interior (138). The main body (106) further includes an upstream end (102) axially spaced from a downstream end (104). The outer surface (112) includes a burner front face (118) at the downstre...

Beschreibung
Zusammenfassung:	A burner (100) includes a main body (106) having an outer surface (112) and at least partially defining an interior (138). The main body (106) further includes an upstream end (102) axially spaced from a downstream end (104). The outer surface (112) includes a burner front face (118) at the downstream end (104) of the main body (106). An annular cooling air plenum (146) is defined in the main body (106) radially inwardly from the outer surface (112). A cooling air passage (152) extends from the outer surface (112) to the annular cooling air plenum (146). A plurality of cooling channels (126) is circumferentially spaced apart from one another along the burner front face (118). Each cooling channel (126) of the plurality of cooling channels (126) extends from a respective inlet (160) in fluid communication with the annular cooling air plenum (146) to a respective outlet (124).
