Abstract
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.
