Gas turbine engine fuel burner

摘要

A gas turbine engine fuel burner suitable for burning diesel fuel oil comprises an annular body and a center body coaxially located within the annular body so that an annular flow path is defined between them. At the upstream end of the burner an annular fuel manifold cooperates with the annular body and the center body to define two coaxial passages which direct air into the annular flow path with minimal turbulence. The low level of turbulence within the fuel burner reduces the possibility of spontaneous combustion occurring within the burner. The center body is hollow and is provided at its downstream end with an end cap which cooperates with the downstream end of the annular body to define a radial fuel/air mixture outlet. Air directed into the interior of the center body provides transpiration cooling of the end plate center portion and is also directed via passages to provide an air flow over the radially outer extent of the downstream face of the end cap to provide cooling thereof and prevent the build-up of carbon thereon.
