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.
Claims12
A method of shutting down a turbine engine having at least one fuel line for conducting liquid fuel from a fuel supply to at least one fuel injector, comprising:
- shutting off the fuel supply;
- passing compressed gas through the at least one fuel line into the combustor to purge fuel from the at least one fuel line and the at least one fuel injector;
- combusting the purged fuel from the at least one fuel line and the at least one fuel injector in the combustor,
- wherein passing the compressed gas comprises providing the compressed gas from a compressed gas source through a regulator, and
- wherein providing the compressed gas comprises regulating the compressed gas pressure.
