Description

Technical Field

[0001] This utility model relates to the field of air intake combustion chamber technology, specifically a guide plate and an annular swirl air intake combustion chamber. Background Technology

[0002] A combustion chamber is a device in which fuel or propellant burns to generate high-temperature gas. It is a combustion device made of high-temperature resistant alloy materials, and the fuel burns in this chamber.

[0003] In the existing technology, the air guide plate on one side of the combustion chamber is a stamped structure. The air duct is formed on the air guide plate through a stamping process. During production, the air guide plate is prone to stamping damage because the stamping depth must be ensured. Utility Model Content

[0004] The purpose of this invention is to provide a guide vane and an annular swirl-flow combustion chamber to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a guide vane, comprising:

[0006] The combustion chamber has a mounting plate fixed to its surface. A combustion atomizing chamber body is fixed to one end of the combustion chamber. An ignition plug nozzle is fixed to the surface of the combustion atomizing chamber body. An air guide plate is provided at the end of the combustion atomizing chamber body. Ignition and combustion-supporting holes are opened on the surface of the ignition plug nozzle. An air intake pipe is connected to the surface of the ignition plug nozzle. The combustion chamber and the mounting plate are welded to the combustion atomizing chamber body. The air intake pipe is welded to the ignition plug nozzle. The cover plate is fixed to the combustion atomizing chamber body by riveting. The atomizing mesh is installed inside the ignition plug nozzle.

[0007] Preferably, the combustion atomizing chamber body and the ignition plug fixing nozzle are die-cast integral structures, and multiple sets of air guide plates are die-cast integral structures with the combustion atomizing chamber body. The air guide plates are evenly arranged in an arc shape on the surface of the combustion atomizing chamber body, and the surface of the air guide plates is covered with a cover plate, which is riveted to the end of the air guide plate.

[0008] Preferably, the surface of the combustion atomization chamber body is provided with powerful combustion-supporting holes, which are connected to the interior of the combustion cylinder. The center of the combustion atomization chamber body is located at the fixed combustion inner cylinder, and the other end of the combustion inner cylinder is located inside the combustion cylinder. The surface of the combustion inner cylinder is provided with combustion-supporting holes, and multiple sets of combustion-supporting holes are provided. The other end of the combustion inner cylinder is sealed. The air inlet pipe is connected to the air supply pipe. When the heater is started, the combustion-supporting fan starts to work, and fresh air is sent into the combustion chamber through the combustion-supporting holes and powerful combustion-supporting holes after changing the air intake method by the air guide plate to provide sufficient oxygen.

[0009] Preferably, a fire-gathering bowl is fixed inside the combustion cylinder, and a hole is opened in the center of the fire-gathering bowl. A sintered felt is provided on the inner wall of the combustion cylinder, and the sintered felt is fixed on the inner wall of the combustion cylinder and located on one side of the combustion cylinder.

[0010] Preferably, the ignition plug fixing nozzle has an internal gas guide groove and an atomizing mesh inside. The atomizing mesh is fixed to the inner wall of the ignition plug fixing nozzle. After the natural gas is depressurized by the gas valve, it is transported to the combustion chamber gas guide groove through the gas supply pipe and the air intake pipe. It is then fully mixed with the air entering through the ignition and combustion aid hole via the atomizing mesh. At this time, the ignition plug generates high temperature and ignites the mixed gas and air to form a flame, which burns in the combustion cylinder.

[0011] Preferably, the powerful combustion-supporting holes are provided in multiple sets, and the multiple sets of powerful combustion-supporting holes are evenly distributed on the surface of the combustion atomization chamber body.

[0012] An annular swirl-flow combustion chamber includes the aforementioned guide vane.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The combustion atomizing chamber body and the ignition plug fixing nozzle proposed in this utility model are integrally molded by die casting, which has a simple manufacturing process and good consistency.

[0015] The air intake duct is directly die-cast from the main body of the combustion atomization chamber, without the need for stamping the air guide plate, thus avoiding the stamping damage problem that exists in stamped air ducts;

[0016] The combustion-supporting holes on the inner combustion cylinder are circular, resulting in gentle airflow and a small air volume, making it less likely to extinguish the flame and reducing combustion noise.

[0017] The ignition and combustion-supporting hole is located in front of the ignition plug fixing nozzle. The ignition and combustion-supporting hole is coaxial with the direction of combustion air intake, resulting in a large air intake and easy ignition. Attached Figure Description
