Problems solved by technology

Continuing to increase the oil-gas ratio will lead to a rich oil working situation near the oil thrower, and the combustion efficiency will be significantly reduced
Researchers at home and abroad have proposed some measures to increase the atomization characteristics of the oil flinger, such as changing the shape of the nozzle outlet, increasing the swirl structure and cavity structure, and increasing the atomization cone angle. It is more applicable in the combustion chamber, and the range of fuel flow for efficient work is small. These oil flinger nozzles cannot solve the above-mentioned problems existing in larger-sized combustion chambers.

Abstract

The present invention provides a radially partitioned oil thrower, which is used for fuel injection in the combustion chamber of a turbine engine, comprising: an oil thrower body connected to the rotating shaft of the turbine engine; a plurality of oil supply pipes arranged on the on the oil pan body; and a plurality of nozzles, arranged at different radial positions of the oil flinger body and the plurality of oil supply pipes, for spraying fuel into the combustion chamber. The oil thrower with radial partitions provided by the present invention realizes efficient matching of fuel and air by adding oil supply pipes and nozzles with nozzles on the body of the oil thrower, thereby improving the efficiency of the combustion chamber under the condition of large oil-gas ratio. The high combustion efficiency can be applied in high-performance combustion chambers with larger size and wider working boundary requirements.

Description

technical field [0001] The invention belongs to the technical field of power plant combustion, and in particular relates to a radially partitioned oil flinger. Background technique [0002] In liquid-fueled combustors, the fuel is injected into the air in a continuous flow of liquid through nozzles, where it is atomized into distinct droplets. The droplets absorb heat from the surrounding environment and evaporate, mix with oxygen in the air and burn. Under the same mass flow rate, the smaller the size of the droplet, the larger the surface area of ​​the droplet, and the faster the rate of evaporation and combustion. The atomization quality and evaporation rate of fuel oil are important factors to increase the fuel combustion rate, improve combustion efficiency, shorten the length of the combustion chamber, and reduce the structural weight. [0003] Oil slinger nozzle is a typical structure in the main combustion chamber of small and medium aero-engines. The oil slinger is...
