城市生活垃圾着火特性研究

Study on Firing and Combustion Properties of Municipal Solid Waste

采用 TG技术 ,分别考察了山西晋城市区生活垃圾不同组分的着火特性 ,实验给出了垃圾燃烧失重和温度随时间的变化曲线 ,即 TG/ T- t曲线 ,并根据 TG/ T- t曲线来确定着火温度 (Ti) ,首次给出 TG技术中垃圾焚烧的着火点的确定方法 ,即 Ti 应取恒速升温 T- t曲线中峰形的第一个拐点所对应的温度。

The fire ignition properties of a municipal solid waste (MSW) in Jingcheng city of Shanxi province were investigated by using the TG technology.The temperatures of ignition (T i) in the MSW combustion were determined by plots of TG/T t.Finally,a way to determine the temperature of the ignition of MSW combustion in TG technology was suggested,that is to say,the temperature of ignition can be determined as the first point of the inflection on the of T t.
