Development of New Stoker Incinerator for Municipal Solid Wastes Using Oxygen Enrichment

Newly developed incineration technology for municipal solid waste (MSW) to reduce dioxins emission from stoker incineration plants incorporates oxygen-enriched primary air to promote intense firing of waste on the grate and recirculated flue gas as secondary air to promote gaseous combustion in the furnace and reduce NOx. Combustion tests conducted using actual MSW incineration facilities demonstrated the excellent performance of this technology in low dioxins emission, reduced flue gas flow rate, the quality of ash, and operation stability. This is believed to be one of the most promising candidates for the next-generation waste incineration technology. 1
