Incineration is an effective means to deal with municipal solid waste,but in the process of waste incineration power generation,as the calorific value of waste increases year by year,the heating surface in the furnace is often faced with the problem of coking,which seriously limits the development of waste incineration power generation.Takes the 400t/d municipal solid waste incinerator as the research object,and uses CFD to conduct numerical analysis on three aspects,such as excess air coefficient,primary air temperature and secondary air ratio,to study the law of its influence on the coking characteristics of the waste incinerator,and optimize the operation parameters.The results show that when the excess air coefficient is 1.4,the primary air temperature is controlled to 150℃,the primary and secondary air ratio is 7:3,and the maximum furnace temperature is 1154℃,which can maintain the daily operation of the incinerator and reduce the ash and slag,providing a theoretical basis for the optimization design of the operating parameters of the waste incinerator.
