    摘要: A description is given of a method for feeding liquid and/or gaseous fuels to gas turbines, by means of which method the same feed path to the burner of the gas turbine can be used for both fuels, the liquid fuel being processed before being fed to the burner. This processing takes place in a fuel pre-evaporator which, for the purpose of processing the liquid fuel, has an evaporator tube 2, which is made of a material with good thermal conductivity, interacts with a heating device (3) and, at its one end, is connected to a feed device (4) for a flushing gas, and, at its other end, is connected to a fuel feed and discharge appliance (5).

    摘要: A reheat burner (1) includes a channel (2) with a lance (3) protruding thereinto to inject a fuel over an injection plane (4) perpendicular to a channel longitudinal axis (15). The channel (2) and lance (3) define a vortex generation zone (6) upstream of the injection plane (4) and a mixing zone (9) downstream of the injection plane (4) in the hot gas (G) direction. The mixing zone (9) includes a high speed area (16) with a constant cross section, and a diffusion area (17) with a flared cross section downstream of the high speed area (16) in the hot gas (G) direction.

    摘要: An exemplary burner of a gas turbine includes a tubular body with an inlet for an entrance of an air flow, downstream of inlet vortex generators, and a lance projecting into the tubular body and having a terminal portion extending along a longitudinal axis of the burner which is provided with nozzle groups for injecting fuel into the tubular body. The nozzle groups can lay in an injection plane perpendicular to the axis of the terminal portion of the lance. Downstream of the lance, the burner has an outlet. A ratio x/L between an axial distance x between the side trailing edge of the vortex generator and the injection plane, and the length L of the tubular body can be less than approximately 0.1052.
