生物质颗粒燃烧过程计算是生物质能利用、火灾过程分析及城市固体垃圾焚烧技术开发的基础。其计算结果的准确度取决于对所研究物理问题的数学模型是否正确。总结了生物质颗粒燃烧涉及的模型。对比了反应区域模型中面反应模型和体积反应模型，指出面反应模型适合计算传输控制过程，而体积反应模型适合计算动力控制或动力传输共同控制的过程。总结了干燥、热解、炭氧化等物理化学变化以及动量、热量和质量传递主要方程及方程中涉及的参数。结果表明，这些方程和参数差异显著，仍需实验研究辅助模型选取。

Calculation of combustion of biomass particle is fundamental to biomass utilization, analysis of fire and waste incineration. The accuracy of the theoretical result depends on the quality of mathematical model In this paper, mathematical models involved in calculation are summarized. Volume reaction model and front reaction model are compared and result show that volume reaction model is suitable to calculate kinetic-controlled or both kinetic- and transport-controlled processes. And front reaction model is suitable to calculate transport-controlled process. Equations and parameters used to calculate drying, pyrolysis, char oxidation, transport of momentum, heat and mass are summarized. It is found that the equations and parameters differ somewhat among different papers and experiments are necessary for model selections.
