CO combustion model for circulating fluidized bed combustor

为了研究一氧化碳在循环流化床燃烧室 ( CFBC)中的燃烧 ,通过对纯气相反应中一氧化碳燃烧速率的若干常用公式的比较识别 ,根据 CFBC内的气固结构特点 ,分析了一氧化碳在循环流化床燃烧室中的燃烧机理 ,提出了一氧化碳有效反应空间的概念 ,从而建立了一种适合于循环流化床燃烧室条件的一氧化碳燃烧计算模型。

For the purpose of calculating CO combustion in circulating fluidized bed combustor (CFBC), several formulas of CO oxidation rate for homogeneous gas phase reaction were evaluated. The mechanism of CO oxidation reaction in CFBC was analyzed based on the characteristics of the CFBC gas solid structure. The concept of effective reaction space was then introduced to develop a calculational model of CO burning rate in CFBC. The calculated results are in good agreement with reported experimental results.
