The burner comprises a burning chamber, a lighting device, a fuel system and an air blowing system, wherein the burning chamber is provided with a rotational flow air distribution disk, the rotational flow air distribution disk is arranged in the front of an oil injection nozzle and a lighting needle, the outer cylinder of the burning chamber is a high-temperature ceramic heat accumulation cylinder, and the high-temperature ceramic heat accumulation cylinder is provided with a rotary air duct. The burner has the advantages that the alcohol base fuel can be burned safely, stably and completely.

Description

technical field [0001] The invention relates to a burner, in particular to a liquid alcohol-based fuel vaporization burner suitable for use in catering stoves. Background technique [0002] At present, industrial burners mainly use diesel oil, heavy oil, liquefied petroleum gas or natural gas as fuel, and the combustion cost is relatively high, and a large amount of CO will be produced after combustion. 2 , SO 2 , N X and other harmful gases, causing serious pollution to the environment. As a low-carbon, multi-hydrogen, and oxygen-containing fuel, liquid alcohol-based fuels mainly emit CO after combustion. 2 And water vapor, with little pollution to the environment, is a clean energy that can replace traditional petrochemical fuels, and is low in cost and safe to use. [0003] In the prior art, there are three types of liquid alcohol-based fuel burners: the first is the liquid surface direct-fired type, which directly injects a certain amount of alcohol-based fuel into a...

Problems solved by technology

[0003] In the prior art, there are three types of liquid alcohol-based fuel burners: the first is the liquid surface direct-fired type, which directly injects a certain amount of alcohol-based fuel into a small container of the stove, and the combustion and vaporization are carried out simultaneously on the liquid surface. It has low combustion temperature, incomplete combustion of alcohol-based fuel, low thermal efficiency, and produces a large amount of harmful gases, pollutes the environment, and wastes energy; the second is the liquid fuel pressurized type, which uses direct pressure to atomize and then burns. The disadvantage is that due to Alcohol-based fuel has a large latent heat of vaporization, and a large amount of heat needs to be absorbed during pressure atomization, resulting in a gradual increase in firepower. When the flow rate of atomized fuel and the flow rate of combustion-supporting air are close to the propagation speed of the combustion flame, the combustion stability of the burner is significantly reduced, resulting in The occurrence of fire-off phenomenon and insufficient fuel combustion and low thermal efficiency; the third is the self-pressurized type, by setting a special vaporizer, using the cavity formed by the burner and the combustion box, and heating the cavity through the heated cavity during combustion Fuel, the fuel vaporizes in the fuel tank to generate pressure. The disadvantage is that the fuel tank has high temperature and high pressure, and it is always fluctuating. In some cases, the pressure in the fuel tank may rise sharply, which may cause the fuel tank to explode. , there is a greater security risk
