Embodiment approach
[0028] As an embodiment of the present invention, the drive unit 7 is a No. 1 rotating disc 71; No. hole 712; said No. 1 hole 711 is a semicircular hole, No. 2 hole 712 is a straight hole, No. 1 hole 711 and No. 2 hole 712 communicate with each other, No. 1 hole 711 and No. 2 hole 712 surround the main fuel pipe 5 distributed in a circle. When working, the air that enters the inside of the cylinder body 1, the air touches the No. 1 rotating disk 71, enters from the No. 1 hole 711 of the No. 1 rotating disc 71, and comes out from the No. 2 hole 712. The air that comes out acts on the sleeve 6. Make the main fuel pipe 5 fixedly connected with the sleeve 6 rotate; since the No. 1 hole 711 is a circular hole, the contact area between the No. 1 rotating disk 71 and the air is increased, so that the air can more fully act on the No. 1 Rotate the disk 71, so as to effectively control the length of the main fuel pipe 5 entering the combustion zone 13, so that more fuel enters the com...

The invention belongs to the technical field of mechanical equipment, and particularly relates to a gas turbine. The gas turbine comprises a cylinder body, a feeding port and air inlet holes; and thegas turbine further comprises folding pipes, sliding telescopic rods, a mounting plate, a main fuel pipe, a sleeve and a driving unit. According to the gas turbine, the entering amount of air is controlled so as to control the entering amount of fuel; under the pushing of the air, the sliding distance of the driving unit determines the length of the main fuel pipe entering into a combustion area,so that the amount of the fuel sprayed into the combustion area is controlled; meanwhile, under the action of the air, the main fuel pipe is enabled to rotate, the fuel is sprayed into the combustionarea in a rotating mode from main fuel spray holes formed on an outer ring of the main fuel pipe, and the contact area between the fuel and the air is increased; and the fuel entering the combustion area is completely burned, so that waste of the fuel is avoided, and the fuel combustion efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to a gas turbine. Background technique [0002] At present, the combustors that emit low-concentration nitrogen oxides mainly adopt the combination of fuel oil classification and lean fuel premixing and pre-evaporation. Play the role of a stable ignition source, ignite the main combustion stage to make it burn stably, the main combustion stage accounts for most of the fuel, it is lean-burn premixed combustion, and the combustion temperature is low, which is conducive to reducing the emission of nitrogen oxides. In the existing gas turbine, two fuel pipelines supply fuel to the main combustion stage and the pre-combustion stage respectively, and the delivery volume of fuel needs to be controlled separately, so the structure and control system are complicated. [0003] There are also some technical solutions for a gas turbine in the prior art. For example, a Chinese pate...
