危险废物焚烧过程中结渣处理方法研究

Research on Slagging Treatment Methods During Hazardous Waste Incineration Process

危险废物焚烧过程中烟道的结焦堵塞问题,不仅会给危废焚烧处置企业的运营带来风险,还会增加额外的运行成本。因此,需要系统分析产生结焦的原因,并采取切实有效的控制手段。根据危废焚烧线实际运行情况,探索危废焚烧系统烟道结焦堵塞问题的解决方案。研究表明,二燃室出口结焦现象可通过喷加重质MgO、Al_(2)O_(3)药剂进行改善,余热锅炉的结焦状况可通过适量吹加熟石灰粉进行改善。

The problem of coking and blockage in the flue during hazardous waste incineration not only poses risks to the operation of hazardous waste incineration disposal enterprises,but also increases additional operating costs.Therefore,it is necessary to systematically analyze the causes of coking and adopt practical and effective control measures.Based on the actual operation of the hazardous waste incineration line,explore solutions to the problem of coking and blockage in the flue of the hazardous waste incineration system.Research has shown that the coking phenomenon at the outlet of the secondary combustion chamber can be improved by injecting heavy MgO and Al_(2)O_(3) agents,and the coking condition of the waste heat boiler can be improved by injecting an appropriate amount of hydrated lime powder.
