Rotary oil spray rod structure

Abstract

The invention provides a rotary oil spray rod structure. The rotary oil spray rod structure comprises an oil flinger body, oil spray holes and oil spray rods, wherein the oil flinger body is connectedwith a rotary shaft of a turbine engine, and an oil collection cavity is formed in the oil flinger body; the oil spray holes are formed in the oil flinger body, communicating with the oil collectioncavity and used for spraying fuel oil in the oil collection cavity out into a combustion chamber; and the oil spray rods are arranged on the oil flinger body, cavities in the oil spray rods communicate with the oil collection cavity, and the oil spray rods are used for spraying the fuel oil in the oil collection cavity out into the combustion chamber. By the adoption of the rotary oil spray rod structure, the fuel oil and air can be matched at high efficiency through addition of structures of the oil spray rods on an oil flinger under an existing combustion chamber structure limiting condition, so that combustion efficiency of the combustion chamber under a large oil-air ratio condition is improved, and the rotary oil spray rod structure can be applied to the high-performance combustion chamber in a larger size and with a requirement for a wider work boundary.

Description

technical field [0001] The invention relates to the field of power plant combustion, and relates to a structure of a rotary fuel injection rod. Background technique [0002] 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. In the combustion chamber research and development project, after the combustion chamber benchmark scheme is determined, a lot of work is usually required to improve the matching of the fuel injection and atomization scheme with the flame stability and propagation structure, so as to further improve the combustion efficiency, broaden the combustion working boundary, and extend the combustion efficiency. The working life of the combustion chamber. Most of the work is concentrated in the research of fuel injection and atomization technology. [0003] The fuel injects the continuou...

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 slinger, such as changing the shape of the nozzle outlet, increasing the swirl structure and cavity structure, and increasing the atomization cone angle. These improved structures are also only suitable for small Flow and small size combustors, where the fuel flow rate for efficient work varies less, these slinger nozzles also cannot be used in larger size combustors
