Benefits of technology

[0011]It is an object of the present invention to solve the aforesaid problems and drawbacks at least partly. In particular, it is an object of the present invention to provide fuel injection means, a swi

Problems solved by technology

Therefore, during part load operations of the gas turbine engine, poor mixing of fuel and air can occur.
The reliability of the gas turbine engine may be affected by such poor mixing of fuel and air.
In addition, due to poor mixing, a good portion of liquid fuel cannot atomize and therefore liquid ligaments often attach and/or are deposited to the internal surface of the components and form a carbon buildup.
When running the gas turbine engine at a part load or at a low load, the engine may

Embodiment Construction

[0029]Elements having the same functions and mode of action are provided in FIGS. 1, 2a, b and 3a, b, c with the same reference signs.

[0030]In FIG. 2a, 2b parts of a swirler 52 according to prior art are shown. In detail, one of the vanes 54 and a mixing channel 56 is shown. In the mixing channel 56 air 24 is channelled from a radially outer end 58 to a radially inner end 60 of the mixing channel 56. Inside the mixing channel 56 a fuel injection means 50 is placed. This fuel injection means 50 is in this embodiment constructed as a fuel injection lance 74. At the end of the fuel injection lance 74 an injection port 62 is located. Through this injection port 62 a fuel injection 66 of fuel 64 into the air 24 is carried out. The shown fuel injection lance 74 is optimized and designed for a full load operation of the gas turbine engine 10. Therefore, at part load operations of the gas turbine engine less fuel 64 is injected 66 into the air 24. An atomization of the complete fuel 64 cann...
