Abstract
A fuel injector is cooled by steam during operation of a combustor. The injector includes a conduit for channeling fuel into the combustor, and a jacket covering the conduit through which steam is channeled for cooling the injector. The steam may be mixed with the fuel, or kept apart from the fuel in the injector by flowing through passageways in the jacket. Cooling can be further improved by expanding the steam through an orifice prior to entry into the injector.
