城市生活垃圾物性与热解特性的实验研究
- Investigation on physical and pyrolysis characteristics of MSW
- 摘要:对城市生活垃圾中常见垃圾成分进行物性及热解特性的实验研究表明, 虽然我国城市生活垃圾(MSW)具有高水分、低热值特点, 但只要能注重其干燥过程, 不投辅助燃料即可维持燃烧.MSW中的有机物是一个很复杂的组份, 并且有机化合物都有较明显的挥发份析出温度区;而纸、布或含纤维质较多的废弃物在不同温度区间的挥发份析出较均匀, 且这一温度区相对较宽.温度、物料尺寸及停留时间对热解过程特性有重要影响, 实验得到停留时间、热解温度、气化率三者间的最佳关系式.
- Abstract:The results showed that the Chinese MSW possess the characteristics of higher water and lower heat value, and MSW can keep burning well without auxiliary fuel but with a sufficent drying.The burning temperature, the size and the staying time of the MSW is affect the pyrotysis, the optimum relationship between them is-given.
