A diffusion flame nozzle gas tip is provided to convert a dual fuel nozzle to a gas only nozzle. The nozzle tip diverts compressor discharge air from the passage feeding the diffusion nozzle air swirl vanes to a region vacated by removal of the dual fuel components, so that the diverted compressor discharge air can flow to and through effusion holes in the end cap plate of the nozzle tip. In a preferred embodiment, the nozzle gas tip defines a cavity for receiving the compressor discharge air from a peripheral passage of the nozzle for flow through the effusion openings defined in the end cap plate.

1. A nozzle fuel tip for converting a dual fuel nozzle to a gas only nozzle configuration comprising:an end cap plate structure for capping the liquid fuel assembly cavity of a dual fuel nozzle, said end cap plate structure having a distal surface, a proximal surface, and a plurality of openings defined therethrough for cooling fluid flow, and a cavity defining structure disposed proximal to said proximal surface of said end cap plate for defining an air cavity proximal to and in flow communication with said openings, said cavity defining structure further including a plurality of cooling air passages extending from an outer peripheral surface thereof to said cavity for the flow of cooling air from said outer peripheral surface to said cavity and a plurality of gas fuel passages extending from a proximal end of said cavity defining structure to a distal end of said cavity defining structure, said air cavity and said fuel flow being substantially isolated by said cavity defining structure.
