摘　　要：大力发展生活垃圾及农林废弃物等生物质直接燃烧发电和煤炭掺烧生物质燃烧发电对缓解我国能源安全问题和实现“双碳”战略目标具有重要意义。然而生活垃圾和农林废弃物中较高含量的碱/碱土金属、硫、氯和硅等元素在高温燃烧过程中会发生复杂交互反应,导致锅炉结焦、积灰和腐蚀等一系列问题,严重影响锅炉的安全稳定运行。通过系统分析生活垃圾和农林废弃物等固体燃料燃烧过程中可能的结焦、积灰和腐蚀形成机理,探讨了原料灰分组成和结焦、积灰、腐蚀形成的关联关系和预测方法,在此基础上比较了不同类型结焦、积灰和腐蚀抑制剂的作用机制及其施加效果,并对未来高效抑制剂的开发进行了展望。Vigorously developing biomass direct combustion power generation and coal-biomass co-firing power generation is of great significance for alleviating the energy security issues and achieving the carbon neutrality target in China.However,the high content of alkali/alkaline earth metals,sulfur,chlorine,and silicon in biomass will undergo complex reactions during the combustion of biomass at high temperature,resulting in a series of problems such as slagging,fouling,and corrosion of boilers,which significantly affect the safe and stable operation of boilers.Herein,the possible formation mechanisms of slagging,fouling,and corrosion during biomass combustion were systematically analyzed.The correlation and prediction methods between the ash composition and the formation of slagging,fouling,and corrosion were established.The application and mechanism of action of different types of inhibitors for slagging,fouling,and corrosion of boilers were compared,and the future development of high-efficiency inhibitors was prospected.
