Plasma melting process for incineration ash of municipal solid waste

The melting and solidification process for municipal solid waste incineration ash is considered an effective technique that reduces the load to landfill sites and that transforms harmful materials into harmless and stable matter. In this study, a demonstration facility with an output capacity of 300 kW, using plasma as a heat source, is used for the purpose of determining the melting characteristics of various types of incineration ash. The features of the plasma method include the ease of obtaining a super-high temperature and high heat efficiency. For sample ash for melting, fly ash and bottom ash from a fluidized bed and a stoker furnace incinerator were used.
