초록 ▼

An assembly of a bulkhead 48 and fuel nozzle guide 62 for a fuel nozzle 46 disposed in a combustion chamber 24 is disclosed. Various construction details which provide for positively cooling components of the assembly are developed. In one detailed embodiment, the nozzle fuel guide is spaced from the bulkhead to form an annular gap G1 which is divided by a heat shield 72 into annular orifices 108, 112 for supplying to cooling air passages 126, 128 bounded by the heat shield 72.

A bulkhead and fuel nozzle guide assembly for an annular combustion chamber having an upstream end, a downstream end, an inner liner, an outer liner spaced radially from the inner liner leaving an annular combustion zone therebetween which is disposed between the ends, and having an annular combustor head at the upstream end which has a supply region for supplying air to the combustion zone, the head including a radially extending bulkhead which bounds the supply region on the downstream end, the bulkhead having an upstream surface, a downstream surface and a plurality of openings spaced circumferentially about the bulkhead which extend through the upstream surface and the downstream surface, each opening having an axis Ab and adapting the bulkhead to receive a fuel nozzle, which comprises: a plurality of fuel nozzle guides, each guide being disposed in an associated opening in the bulkhead, the guide having an axially extending hole through the guide which is disposed about an axis Af and which adapts the guide to receive an associated fuel nozzle, the guide being spaced axially downstream from the bulkhead leaving a radially oriented plenum for cooling air therebetween and extending radially upstream from the first member past the bulkhead to adapt the guide to engage a fuel nozzle guide retainer and being spaced radially inwardly from the bulkhead leaving a first annular supply gap therebetween for supplying cooling air to the cooling air plenum; a heat shield at each opening which abuts circumferentially with the circumferentially adjacent heat shields to form a heat shield assembly, each heat shield being disposed in the radially oriented cooling air plenum and the first annular supply gap between the bulkhead and the fuel nozzle guide, the heat shield being disposed in the plenum and spaced axially from the downstream surface of the bulkhead to form a first radially extending passage for cooling air therebetween, and being spaced axially from the first member of the nozzle guide to form a second radially extending passage for cooling air therebetween downstream of the first passage for cooling air, and, having a lip extending axially which is disposed in the annular gap to divide the annular gap into a first annular supply orifice for directly supplying cooling air to the first passage and a Second annular supply orifice for directly supplying cooling air to the second passage; and; a nozzle guide retainer facing the upstream surface of the bulkhead, the retainer having an axis Ar which is coincident with the axis Af of the hole in the fuel nozzle guide; wherein the fuel nozzle retainer is integrally joined to the fuel nozzle guide and traps the assembly in the axial direction to the bulkhead, and wherein the supply region is in flow communication with the second annular gap and flow through the gap is metered through the orifices to the cooling passages without the use of impingement holes in the bulkhead to cool the heat shield assembly under operative conditions of the combustion chamber.
