Classification: CPC F  B | IPC B  F

Claim 19:
20. An apparatus to produce propulsion in a gas turbine engine comprising:
means for priming to provide thermal energy to a fuel circuit during a first operation of the gas turbine engine;
means for purging the fuel circuit, the means for purging to receive the thermal energy from the means for priming;
means for combusting to flow through the fuel circuit; and
means for processing to cause the fuel circuit to include (i) the means for purging during a second operation of the gas turbine engine after the first operation in response to a temperature of the fuel circuit satisfying a temperature threshold, (ii) the means for purging and the means for combusting during a third operation of the gas turbine engine after the second operation, and (iii) the means for combusting during a fourth operation of the gas turbine engine after the third operation.
