Abstract

Combustion chambers for gas turbine engines and, more particularly, an annular combustion chamber. The combustion chamber comprises a flame tube having a back wall through which several vaporizers project into the flame tube or combustion zone. Each vaporizer has a pipe section extending within the flame tube, fuel supply and also supply ports in communication with the pipe section, and at least one outlet port for supplying a vaporous fuel-air mixture from the pipe section to the flame tube. Outlet ports of adjacent vaporizers are arranged spaced-apart from and facing one another, whereby a zone of maximum turbulence is formed between the outlet ports.
