Classification: CPC F | IPC F

Claim 18:
19. A method for operating a turbine engine with a flowpath, the method comprising:
processing ammonia with a fuel injection system to provide first fuel and second fuel, the first fuel comprising at least the ammonia, and the second fuel comprising at least hydrogen gas extracted from the ammonia;
directing the first fuel into a cowl plenum located upstream of a combustion chamber such that the first fuel flows from the cowl plenum through a plurality of swirler vanes arranged around an inlet into the combustion chamber, the combustion chamber extending radially between an inner combustor wall and an outer combustor wall, the combustion chamber separated from the cowl plenum by a combustor bulkhead, the cowl plenum extending radially between opposing inner and outer sides of a combustor cowl, the first fuel thereafter flows along the flowpath into the combustion chamber;
separately directing in parallel the second fuel into the flowpath at the inlet into the combustion chamber downstream of the plurality of swirler vanes; and
combusting the first fuel and the second fuel within the combustion chamber.
