Abstract
A method of operating a gas turbine engine is provided. The method includes introducing a fuel into a combustor, detecting a failure of ignition of the fuel, and preventing ignition until the introduced fuel is substantially removed from the gas turbine engine.
Claims31
A method of operating a gas turbine engine, said method comprising:
- supplying a fuel into a combustor;
- detecting a failure of ignition of the fuel;
- detecting a level of residual fuel present within the gas turbine engine;
- and
- preventing ignition until residual fuel is substantially removed from the gas turbine engine.
2 more elements
A gas turbine system comprising:
- a gas turbine engine comprising a combustor section and a turbine section;
- at least one fuel level detector coupled within at least one of the combustor section and the turbine section;
- a drain line coupled to a low-point of at least one of the combustor section and the turbine section;
- and
- a control system configured to:
- receive a signal indicative of a failure of ignition of the combustor section;
- and
- prevent ignition of the combustor section until fuel introduced to the gas turbine engine is substantially removed from the gas turbine engine.
