In-furnace control method for avoiding generation of dioxin

Dioxin is a pollutant generated by an incineration behavior, and the precondition of dioxin generation is that halogen elements and organic matters exist. In the incineration process, a halogen element reaction active agent is sprayed at a flue gas outlet under the high-temperature condition (800-1200 DEG C), the mass ratio of the reaction active agent to halogen elements is (10-50): 1, the reaction active agent is alkaline micro powder, the alkaline micro powder adsorbs the halogen elements by means of self activity and then reacts with the halogen elements to generate stable halides, and the halogen elements are effectively consumed so that dioxin cannot be generated due to lack of the halogen elements. 二噁英是焚烧行为产生的污染物质，二噁英生成的前提是有卤族元素和有机物存在。本发明是在焚烧过程中，在高温条件下(800℃-1200℃)在烟气出口处喷射卤族元素反应活性剂，反应活性剂与卤族元素的质量比为(10-50)：1，该活性试剂为碱性微粉，碱性微粉依靠自身活性吸附卤族元素后与卤族元素反应生成稳定的卤化物，有效消耗卤族元素，使二噁英因缺乏卤族元素而无法生成。
