摘要
固体回收燃料(SRF)是由城市生活垃圾(MSW)经机械生物处理(MBT)而得,具有高热值、低氯和含汞的特点,是继垃圾衍生燃料(RDF)之后的一种新型燃料。目前SRF焚烧技术在国内外已有一定的基础研究,但仍需要向大规模、高参数(高蒸汽温度和压力)、稳定运行方向发展。从垃圾焚烧现状入手,简述了国外SRF焚烧和共处置技术的研究现状,同时回顾了国内对MSW和RDF焚烧技术的相关研究,分析了SRF焚烧和共处置时污染物排放的规律,以及SRF对共处置锅炉运行工况的影响。最后指出了实现SRF焚烧技术的大规模、高参数工业应用必须研究的3个方面,包括:SRF的分类方法和燃烧模型,烟气净化系统的改进,SRF焚烧对锅炉腐蚀、结渣和积灰生长的影响。
Solid recovered fuel(SRF)was made from municipal solid waste(MSW)by mechanical-biological treatment(MBT),with the characteristics of high calorific value,low chlorine and mercury-containing.It was a new type of fuel following the refuse derived fuel(RDF).Although there were some basic researches at home and abroad,SRF incineration technology still needed the deep research on large scale,high parameters(high steam temperature and pressure)and stable operation.Based on the state of MSW incineration,the present research of SRF incineration and co-disposal abroad was described.At the same time,domestic researches on MSW and RDF incineration technology were reviewed.Emission of fine particles and pollutants was analyzed,as well as the impact on the boiler operation.At last,three fields were put forward to realize the application of SRF incineration in large-scale and supernal parameters,including SRF classification method and combustion model,improvement of flue gas purification system and influence of SRF incineration on boiler corrosion,slagging and ash growth.
