Abstract:
The purging of residual fuel in gas turbine combustor fuel injectors is disclosed in which the fuel injector includes a fuel element having a first and second fuel passage for discharging the fuel to the combustor of the gas turbine. Upon interruption of the fuel to the fuel element, high pressure air is passed through an air passage to the first fuel passage to force the fuel in the reverse direction through the first fuel passage, through the second fuel passage, and discharge the residual fuel in each of the passages to the combustor through the second fuel passage.
