摘　　要：通过热重分析方法研究了稻秆的燃烧过程及其动力学特性。非等温热重法的升温速率分别为20℃/min、30℃/min、40℃/min,加热终温800℃;采用空气为载气。得到稻秆燃烧的TG、DTG曲线,研究了加热速率、温度对燃烧过程的影响,建立了稻秆燃烧的反应动力学方程,由Freeman-Carroll法得到该类稻秆燃烧动力学参数,并提出了相应的燃烧机理。为燃烧稻秆锅炉的设计开发提供了理论支持。The project investigated the combustion process of rice straw together with its kinetics characters using thermodynamic method. The rice straw was burned in air at the heating rate of 20℃/min, 30 ℃/min, 40℃/min. The final temperature was up to 800℃. From the plot of TG and DTG, the researchers has studied the influence of heating rate and temperature on the combustion process and buih a kinetic equation of the reaction. The kinetic parameters of this kind of rice straw were obtained by Freeman - Carroll method. The combustion mechanism suggested will theoretically support the design of the boiler with rice straw as fuel.
