ABSTRACT:
A fuel nozzle tip construction for a dual fuel gas turbine includes a centrally arranged metal liquid fuel tip having a liquid fuel flow passage therein; a radially outer ceramic atomizing air tip surrounding the liquid fuel tip in radially spaced and substantially concentric relationship such that an atomizing air passage is formed therebetween; a radially outermost metal gas fuel tip surrounding the atomizing air tip in radially spaced and substantially concentric relationship such that a gas fuel passage is formed therebetween; a metal retaining cup radially between the atomizing air tip and the gas fuel tip; and a pair of compliant interface elements, one interposed between the gas tip and the atomizing air tip at a forward end of the atomizing air tip, and the other interposed between the retaining cup and the atomizing air tip at a rearward end of the atomizing air tip.
