摘要
随着垃圾焚烧工艺的广泛采用,焚烧飞灰产量越来越大,飞灰出路问题日趋紧迫。探讨了垃圾焚烧飞灰作为水泥原料的可行性,分析了由此带来并需要解决的重金属挥发、二恶英类有机物、氯元素导致水泥窑结皮和钢筋中毒等三大问题,最后介绍了目前国内飞灰作为水泥原料的应用情况。
Municipal solid waste incineration generates lots of fly ash. So a new safe and resource utilization method is pursued. The probable of MSWI fly ash as a cement raw material was discussed and three problems of the evaporation of the heavy metals, the organic compounds (such as dioxin) , and the chloride salts in fly ash were analyzed. The application of fly ash as a cement raw material in China was introduced.
