Problems solved by technology
In the actual operation of gas turbines, sometimes different injection velocities are required to meet the actual needs. The usual method is to replace a new nozzle. Therefore, the gas turbine needs to be configured with a large number of nozzles (especially for test debugging), and the cost is high.

The invention relates to the technical field of display, and discloses a nozzle, a combustion chamber and a gas turbine. The nozzle comprises a shell which is provided with a fuel inlet and a fuel outlet; and a flow guide body, wherein at least part of the flow guide body is arranged in the fuel outlet and the flow guide body is matched with the fuel outlet to form an injection opening, the flow guide body can move in the axis direction of the fuel outlet, and the flow area of the injection opening changes along with the change of the position of the flow guide body in the axis direction. According to the nozzle, the flow guide body and the fuel outlet of the shell are matched to define the injection opening, and the flow guide body can move in the axis direction of the fuel outlet so thatthe flow cross section area of the injection opening changes, that is, the flow area of the outlet of the nozzle can be changed by adjusting the axial position of the flow guide body and then the jetspeed of the nozzle is changed; in conclusion, the outlet jet velocity of the nozzle can be changed and thus the requirements of the gas turbine for different fuel injection speeds can be met.
Description
technical field [0001] The invention relates to the technical field of gas turbines, in particular to a nozzle, a combustion chamber and a gas turbine. Background technique [0002] With the continuous improvement of pollution prevention and control standards, gas turbines are getting more and more attention. The combustion products of gas turbines mainly include NOx (nitrogen oxides), CO (carbon monoxide) and UHC (unburned hydrocarbons), and their emissions are much lower than those of traditional coal. and fuel burn. According to the power range, gas turbines can be divided into: micro gas turbines, small gas turbines, light gas turbines and heavy gas turbines. [0003] Taking micro gas turbine as an example, its core components include combustor, compressor and turbine. The combustion chamber is the power source of the gas turbine, and its performance directly affects the overall performance of the entire gas turbine. The nozzle is a key component of the combustion cha...
