Combustion method

In a gas turbine engine, inlet air is continuously compressed, mixed with fuel in an inflammable proportion, and then contacted with an ignition source to ignite the mixture that will then continue to burn. The heat energy thus released then flows in the combustion gases to a turbine where it is converted to rotary energy for driving equipment such as an electrical generator. The combustion gases are then exhausted to the atmosphere after exchanging some of their remaining heat to the incoming air provided from the compressor. Upon shutdown of a liquid fuel turbine engine, the liquid fuel supply is turned off and compressed air is passed through the fuel lines and fuel injectors to purge all remaining liquid fuel into the combustion chamber to be combusted therein.
