Abstract
A lance for a hybrid burner of a combustor of a gas turbine, includes an inner passage for a liquid fuel, an outer passage coaxially enclosing the inner passage for a gaseous fuel, a plurality of star like arranged outer nozzles branching off radially from the outer passage, a plurality of inner nozzles, which branch off radially from the inner passage and which each extend coaxially inside one of the outer nozzles, and a distributor section, which is arranged upstream of the outer nozzles in the outer passage and has a plurality of star like arranged, coaxially extending through-openings for the gaseous fuel. In order to reduce the flow resistance in the gas path of the lance, the through-openings each have an opening width which is larger in the circumferential direction than in the radial direction.
