本文对抚顺、茂名颗粒页岩的燃烧动力学进行了研究。实验数据表明,颗粒页岩的恒速升温燃烧及快速升温后的等温段燃烧均符合不变粒径的缩核反应,即包括气膜层外扩散、灰分层内扩散及化学反应动力学三项阻力同时存在的燃烧动力学模型。在Universe-68计算机上,用改进的Simplex优化法及Simplex-Runge-Kutta法,以燃烧时间的实测值与计算值的偏差最小作为最佳目标,分别求解了上述两种页岩在两种燃烧条件下的各项动力学参数,实测值与理论值吻合较好。作者用总包一级反应模型对快速升温实验的快速升温段燃烧实验数据进行处理,得到较为满意的结果。
In this paper, combustion kinetics of Fushun and Maoming particle shale has been studied. The experimental data show that the constant temperature combustion of particulate shale and the isothermal combustion after rapid heating all conform to the invariant particle size shrinkage reaction, which includes the out-diffusion of gas film, the diffusion within ash layer and the chemical reaction kinetics Combustion kinetic model with simultaneous existence of resistance. On the Universe-68 computer, with the improved Simplex optimization method and the Simplex-Runge-Kutta method, the deviation between the measured value and the calculated value of the combustion time is the best. The two kinds of shale Under the conditions of the kinetic parameters, the measured value and the theoretical value is in good agreement. The authors use the total package first-order reaction model to deal with the experimental data of fast-heating combustion in fast-heating experiment and obtain satisfactory results.
