摘　　要：建立了一种适合于循环流化床燃烧室 (CFBC)条件下可燃气体的燃烧计算方法。对纯气相反应中CO和CxHy 燃烧速率的若干常用公式作了比较识别。根据CFBC内的气固结构特点 ,利用有效反应空间的概念 ,将此方法用于循环流化床模型计算 。A method suitable for calculating the burning rate of combustible gas in CFBC has been created.Several formulae commonly used for calculating the burning rate of CO and C XH Y in the reaction of pure gaseous phase were compared and distinguished.Based on the features of gas-solid composition in CFBC,the conception of effective reaction space is applied for using the said method to calculate the model of CFB.The calculated result tallies well with the reported experimental results.
