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.

Combustion chamber for gas turbine engines

The useful life of a gas turbine combustion chamber and especially its flame pipe is increased by an improved cooling arrangement which branches off a small proportion of the air from the compressor upstream of the combustion chamber. The branched off air is directed into the combustion chamber and onto the flame pipe so that it flows in a cooling manner around at least the front end of the flame pipe without initially substantially participating in the combustion.
