Embodiment Construction

[0020] The present invention will be further described now in conjunction with accompanying drawing:

[0021] combine figure 1 The overall appearance of the centrifugal nozzle of a new type of gas turbine combustor, figure 2 Global cross-sectional view of a novel centrifugal nozzle for a gas turbine combustor, image 3 Fuel inlet / nozzle tail diagram of a new type of centrifugal nozzle for gas turbine combustor A new type of centrifugal nozzle for gas turbine combustor is realized, the invention can strengthen the atomization effect, achieve high combustion efficiency and low emission.

[0022] Specific process: the fuel enters the main oil passage under a certain pressure ( figure 2 1) in the auxiliary oil passage (2 in Figure 2), passing through the cyclone at the end of the straight passage of the oil passage ( figure 2 6) realizes the high-speed rotation of the fuel, passes through the outlet of the contraction section of the fuel road, and the swirl blades of the swi...

Abstract

The invention discloses a novel centrifugal nozzle of a combustion chamber of a gas turbine. Compared with a common centrifugal nozzle, the nozzle is characterized in that two paths of rotating fuel oil pass through oil path holes and are finally collided and broken at a certain part of a contraction section through rotation constraint of swirlers on double oil paths, primary atomization is achieved, the fuel oil is blown out of the nozzle through a middle air hole of an air passage finally, secondary atomization is achieved, and the atomization effect is enhanced finally. The swirlers of a main oil path and an auxiliary oil path are identical in rotating direction, it is guaranteed that two paths of fuel oil rotate and collide at the contraction section, the good atomization and crushing effect is achieved, the good atomization effect of the nozzle is beneficial to organized combustion in the combustion chamber of the gas turbine, the combustion condition can be enhanced, and the combustion efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of combustion chambers of gas turbines, and in particular relates to a novel centrifugal nozzle of combustion chambers of gas turbines. Background technique [0002] At present, gas turbine, as a power device for energy conversion, occupies a dominant position in the fields of military, aviation and power generation. People have been making major changes and efforts to improve some attributes of gas turbines, making gas turbine technology have been improving and develop. However, the current development of gas turbines still poses a huge challenge to us. Combustion efficiency, reduction of environmental pollution, structural size restrictions, new technology and new requirements are all things we must consider. [0003] In order to save fuel and improve combustion, the atomization of fuel is the top priority of our research. The result of fuel atomization determines whether the air from the swirler can be i...
