通过建立单颗粒焦炭粒子燃烧的数学模型，并利用计算机求解，探明了循环流化床锅炉中焦炭粒子含碳量随粒径变化呈峰值特征这一现象的物理本质。结果表明，焦炭的粒径越小，其表面温度越接近于床内温度，而且焦炭粒子的燃烬时间随粒径变化的曲线将出现峰值。本文还提出了一些改进燃烧的措施。
By establishing a mathematical model of single particle coke combustion and solving the problem by computer, the physical essence of the phenomenon that the carbon content of coke particles in the circulating fluidized bed boiler changes with the particle size is characterized. The results show that the smaller the coke particle size is, the closer the surface temperature is to the temperature in the bed, and the longer the burning time of coke particles with the particle size curve will appear. The paper also proposes some measures to improve combustion.
