Abstract

The invention relates to a rapid-mixing tubular flame burner with an axial jet function. The burner comprises a burner body and an axial jet device. A cyclone mixing cavity is formed in the burner body. The burner body further comprises at least two airflow inlets communicating with the cyclone mixing cavity in the tangential direction of the cyclone mixing cavity. According to the burner, fuel and an oxidizing agent are injected into the burner from tangential thin-slot inlets evenly distributed in the circumference correspondingly, and backfire and even explosion can be prevented under the conditions that the flow speed is low or the oxygen concentration is high and even pure oxygen exists. According to the burner, a large-density low-temperature unburned gas film is formed on the inner wall of a quartz glass tube through the aerodynamic characteristic, and a flame area inside the quartz glass tube is wrapped, so that heat transfer between flames and the wall surface is reduced, heat loss is effectively reduced, the heat utilization rate is high, a high temperature can be easily obtained, and the flame cutting quality and the yield of nano-particles synthesized through the flames are improved.

Description

Technical field [0001] The invention relates to the field of combustion, in particular to a rapid mixing tubular flame burner with an axial jet. Background technique [0002] Since the establishment of the China Welding Society and China Welding Association, the two sessions have made outstanding contributions to the development of the cutting industry, cutting technology, and promotion and application. At this stage, flame cutting is widely used in industry. For cutting low-carbon steel plates with a large thickness (greater than 20mm), flame cutting has the advantages of energy saving, low cost, high cutting quality, and high production efficiency. Has been widely used. It is widely used in my country's shipbuilding and automobile fields. In addition, the flame synthesis of nanomaterials has gradually attracted people's attention. Because the hydrocarbon flame can provide a high-temperature environment and carbon source, the required combustion equipment is relatively simple,...
