城市生活垃圾中主要可燃组分的热解及燃烧特性研究

准确掌握城市生活垃圾的热化学特性,对制定城市生活垃圾热处理方案、确定具体工艺参数起着不可或缺的作用。因此对城市生活垃圾各物质热化学特性的检测显得尤为重要。试验采用热重仪分别在氮气和空气两种气氛下,对垃圾中各种主要可燃组分的热解和燃烧特性进行了分析。实验结果表明:垃圾中不同组分的热失重差异较大,在进行相关工艺设计时,必须针对不同地区城市生活垃圾组成的特点,全面考虑其中起决定作用组分的热物理特性,以期获得最佳的配合处理效果。

Study on thermolysis and burning of the main combustible components of city refuse

Accurately grasp the thermochemical property of city refuse is indispensable to institute thermal treatment scheme of city refuse and decide the material technical parameters and accordingly test the thermochemical property of main components in city garbage gets particularly important. Thermolysis and burning of the main combustible components of city refuse were analysed by thermogravi- metric apparatus in hydronitrogen and atmosphere in this experiment. And the results show that different component of the city waste has obviously different thermal weight change, and in relative process design, to gain perfect deposal effect we should consider the main componets＇ thermal property aiming for different area＇s city refuse.
