Abstract
A head part of an annular combustor for a gas turbine includes an annular bulkhead at the upstream end of the combustor. The bulkhead includes a first annular section integrally, inwardly and radially extending from the outer annular wall of the combustor, and a second annular section integrally, outwardly and radially extending from the annular inner wall of the combustor. The first and second annular sections are overlapped adjacent to the annular inner wall and secured together by segmented heat shields which have integrated threaded studs engaging with self-locking nuts, and cover the downstream side of bulkhead. The first annular section has a plurality of apertures circumferentially spaced apart from one another to receive fuel burners. Each burner is radial-displaceably positioned in the aperture and sealed by a burner collar, which is clamped between the heat shield and the bulkhead wall. This provides a simple configuration of a head part of combustor in which heat shields are used to interconnect sections of bulkhead and secure the burner collar to the bulkhead.
