城市固废焚烧是固废污染治理的主要方式,也是可再生能源的来源之一,能为国家生态文明建设和“双碳”战略提供重要支撑。城市固废焚烧过程内嵌了系列物理、化学反应,运行机理复杂、演化机制不清,尤其是我国固废含水率高、热值低、随时空动态波动,难以实施智能优化控制,导致固废燃烧不完全、烟气排放不稳定、能源转化率低、运行成本高等问题时有发生,制约城市固废焚烧行业高质量发展。本文分析了实施城市固废焚烧过程智能优化控制所面临的难点问题,梳理了城市固废焚烧过程智能优化控制关键理论与核心技术的主要进展,凝练出实现高效化和绿色化运行待解决的关键科学问题,探讨了未来研究方向。

Municipal solid waste incineration(MSWI)provides an effective and promising approach for managing municipal solid waste(MSW)due to the fact that it can reduce waste volume and recover energy.MSWI has become an important support for the ecological civilization construction and dual carbon target.The MSWI process involves various physical and chemical reactions,with complex mechanisms and unclear evolution rules.Furthermore,the MSW in China is with high variability in composition and characteristics,making it difficult to achieve the intelligent optimized control.In consequence,there is a series of barriers in the development of MSWI industry,including the incomplete combustion of MSW,the excessive emissions of flue gas pollutants,the low energy efficiency,and the high operating cost.In this regard,after analyzing the challenges faced by realizing the optimized control of MSWI processes,this paper reviews the development status in both theory and application.Finally,the key scientific problems are issued and the potential research directions are prospected.
