PURPOSE: An injector tip assembly and a method for injecting fuel are provided to prevent first air from being pre-mixed with fuel, and to prevent combustion products which flow back through the opening of a central member. CONSTITUTION: An injector tip for a nozzle comprises a central member(12), one or more fuel paths, and one or more oxygen paths. The central member comprises a plurality of openings(16) at the end part. The central member injects fuel flow(32) into a combustion area(34). The fuel paths are placed on the circumference of the central member to inject fuel slurry into the combustion area. The oxygen paths are arranged on the circumference of the central member to inject air flow into the combustion area. One of the fuel paths or oxygen paths comprises the same center with the central member. |
