Abstract:

Furnace slagging is considered to be one of the common problems in the incineration industry, especially in the field of municipals solid waste (MSW) incineration. The slagging problem of MSW incineration will increase the maintenance cost of the incinerator, reduce the heat exchange efficiency, and ultimately affect the incinerator safety, stability and life period. Aiming at this slagging problem of MSW incineration, the mechanism and prevention of slagging related to waste incineration in recent years were systematically reviewed. The formation process between slagging reactants and slagging products were discussed, and the influencing factors of slagging were summarized. This paper discussed the prevention and control measures of Slagging in incineration process, such as feeding waste pretreatment, anti-Slagging Agents and operation adjustment et al. The main problems needing to be solved in the future are also proposed, with the aim to provide reference for the prevention and management control of slagging in MSW incineration.
