Abstract
A combustor module includes a pre-vaporizing chamber defined by an inner wall, and an outer wall, and a heat shield. The heat shield separates the pre-mixing zone from the reaction zone of the combustor. At least one fueling nozzle is disposed in the pre-vaporizing chamber for injecting fuel into the pre-vaporizing chamber. Fuel from the fueling nozzle is sprayed onto the surface of the heat shield, thereby simultaneously vaporizing the fuel and cooling the heat shield. The heat shield also includes a pilot fueling spray opening to allow fuel to pass directly into the reaction zone of the combustor to provide a piloting flame stability region therein.
