Abstract
A pressure atomizing nozzle for injecting fuel includes an inlet housing configured to thermally isolate the interior space from external conditions and to remain relatively cool under operation so as to substantially eliminate heat soak back from the inlet housing to the interior space thereof after operation. First and second coolant conduits cool the nozzle tip region actively during operation and passively after operation. A cooling air jacket is configured to thermally isolate inboard components from exterior conditions, to provide clean air during operation to the nozzle tip region for diluting carbon to reduce carbon deposits in the nozzle tip region and for cooling the same, and to provide passive cooling to the nozzle tip region after operation.
