The combustor comprises a body and the like; a spraying opening is formed in the body, a nozzle is welded to the body, the lower end face of the nozzle and the upper end face of the spraying opening are tightly attached, a fuel inlet is welded to the nozzle, an oxidizing agent inlet is welded to the body, a sparking plug is connected with the body through a thread, the sparking plug and the body are sealed through a seal ring, an annular gas collection cavity is formed by the body and the nozzle, a pre-mixing cavity is formed by the spraying opening and the nozzle, the body is provided with a combustion chamber and a spraying pipe, the spraying opening is provided with a shrinkage type flowing channel, the nozzle is provided with a fuel injection hole and an oxidizing agent injection hole, gaseous fuel enters the pre-mixing cavity through the fuel inlet and the fuel injection hole, and the reliable ignition and stable combustion functions are achieved.

Description

technical field [0001] The invention relates to a combustor, in particular to a combustor for a micro gas and gas bicomponent propellant. Background technique [0002] Miniature gas / gas bicomponent engines generally use oxygen / hydrocarbon fuel as propellant, and use electric igniter to ignite. It has the advantages of green, non-toxic, high energy, clean combustion, and simple system. It is often used as an ignition torch for large engines. And it has application potential on other power devices. In the high-altitude and low-pressure environment, the combustion chamber of conventional engines has a fast flow rate and a low concentration of combustibles, making it difficult to ignite and stabilize the flame. [0003] Still do not find explanation and report with similar technology of the present invention at home, also do not collect similar data at home and abroad yet. Contents of the invention [0004] Aiming at the defects in the prior art, the object of the present in...
