燃烧净化法的原理是利用高温燃烧所产生的热量进行氧化反应，把油烟废气中的污染物质转化为CO2和H2O等物质，从而达到净化目的。在燃烧过程中，让油烟废气通过自净化催化剂，催化剂的催化反应有利于污染物的转化。一般采用陶瓷或金属蜂窝进行载体进行氧化催化。这类油烟净化设备只适用油烟浓度很低的场合，如食物生吃或制作半成品。
The principle of combustion purification method is to use the heat generated by high-temperature combustion to carry out oxidation reaction, so as to convert the pollutants in the flue gas into CO2, H2O and other substances, so as to achieve the purpose of purification. In the combustion process, let the flue gas pass through the self purification catalyst. The catalytic reaction of the catalyst is conducive to the transformation of pollutants. Generally, ceramic or metal honeycomb is used as support for oxidation catalysis. This kind of fume purification equipment is only suitable for occasions with very low fume concentration, such as raw food or semi-finished products.
缺点：催化燃烧净化设备的开发还不十分成熟。
Disadvantages: the development of catalytic combustion purification equipment is not very mature.
