    摘要: A burner assembly for a gas turbine is provided. The burner assembly has a combustor, a centrally arranged pilot burner and plurality of main burners surrounding the pilot burner. Each main burner has a cylindrical housing having a lance which is centrally arranged therein and has a fuel channel for liquid fuel. The lance is supported on the housing by swirl blades and an attachment is arranged on the lance in the direction of the combustor. The liquid fuel nozzle is arranged in the attachment downstream of the swirl blades and connected to the fuel channel. For the improved mixing of the fuel with the air, the liquid fuel nozzle is designed as a full jet nozzle and the full jet nozzle has a length and a diameter, the ratio of the length to the diameter is at least 1.5.

    摘要: A fuel nozzle for imparting swirl to a fuel/fuel-air mixture is provided. The fuel nozzle includes a holding unit and a nozzle insert, wherein the holding unit and the nozzle insert form a flow path and subsequently a swirl chamber, wherein the nozzle insert includes an inlet start and an inlet end. The inlet start and the inlet end are bent in a substantially circular manner such that an unbroken circle is formed, such that a fuel flowing into the swirl chamber has imparted to it a radially inwardly directed circular, in particular spiral movement. A burner and a gas turbine are also provided.
