城市生活垃圾中可燃物宏观反应机理的探讨

Macroscopical Reaction Mechanism of Combustibles in Municipal Solid Waste

对城市生活垃圾中的 8种可燃物进行了热重分析 ,得到了各种成分的燃烧特性参数 ,将积分法和微分法相结合 ,选用合适的反应机理方程来求解反应动力学参数 ,避免了把机理方程限制为 (1-α) n和采用单一方法处理热重曲线而产生的误差 .

Thermogravimetric analyses of eight combustibles in the municipal solid waste are carried out. Combustion characteristic parameters of various components are gained and integral method in combination with differential method is used. Proper reaction mechanism equation is chosen to attain reaction kinetic parameter as well. Therefore, the errors resulting from limiting mechanism equation to (1- α) n and adopting a single method to dispose thermogravimetric curves can be avoided.
