Problems solved by technology

However, in VRT, the circumferential swirl is generated in the entire flame tube, and its stability is poor, so it is not suitable for the combustion organization under the condition of strong swirl inlet.

Embodiment Construction

[0028] like figure 1 , 2 , 3, the present invention is mainly composed of an inner casing 3, an outer casing 2, an inner flame cylinder 5 and an outer flame cylinder 4, and the outer flame cylinder 4 is uniformly equipped with a head 1 and a main combustion hole 8 along the circumferential direction, according to The number of oil supply heads is generally between 2 and 20 according to different inlet air volume, swirl degree and structural size requirements. Different nozzles can be used under different oil supply pressures and flow rates. At present, centrifugal nozzles are optional. There are two types of air atomizing nozzles; the main combustion hole 8 is located downstream of the head 1, and the inclination angle between the center line of the head 1 and the main combustion hole 8 and the circumferential tangent is 15°-75°; the head 1 includes the oil supply nozzle 6 and fire stabilizing tube 7; the outer mixing hole 9 and the inner mixing hole 10 are respectively locat...

Abstract

The tangential standing vortex burning chamber in annular flame tube structure consists of inner and outer boxes and inner and outer flame tubes separately inside the inner and the outer boxes. The outer flame tube has one circumferential head including oil nozzle and flame stabilizing tube, and one main burning hole in the downstream of the head, and the central line of the head and the main burning hole is in some angle to the circumference tangent. The inner and outer flame tubes have inner and outer mixing holes separately in front of their combustors to ensure the excellent outlet temperature distribution, and inclined cooling holes in the walls and inclined to the main burning holes. The present invention has raised liquid atomizing combustion efficiency, reduced combustor outlet temperature distribution coefficient and expanded stable operation range of combustor.

Description

technical field [0001] The invention relates to a novel combustion system suitable for high tangential velocity of the inlet airflow, especially for a tangential vortex combustion chamber for a gas turbine with a high tangential velocity at the inlet of the combustion chamber. Background technique [0002] Foreign countries have developed a new concept engine-ramjet rotor engine integrating ramjet engine technology and gas turbine engine technology. This kind of engine can be divided into two categories: one type of ram rotor engine uses ram rotor to compress air, followed by combustion chamber and turbine for combustion and work; the other type is to realize gas compression, combustion and expansion work on one rotor . Ramgen Corporation of the United States has conducted research and operational tests on both types of ram rotor engines, and its main purpose is to apply ram rotor engines to provide power for industrial gas turbines, and both use gaseous fuels. [0003] Fo...
