Abstract
A fuel injection system has a fuel lance for supplying gaseous fuel to the burner of a gas turbine engine. The fuel lance includes a gas sensor that is used to monitor the concentration of the methane fuel inside the gas pilot channel of the fuel lance. The invention prevents overheating caused by the ignition of the methane fuel inside the fuel lance by monitoring the concentration of the methane fuel during the purge sequence and taking action if a critical fuel air mixture is reached.
