摘　　要：:针对流化床 -煤粉复合燃烧锅炉的特点 ,在综合考虑流化床、火焰和受热面之间换热的基础上 ,推导了流化床 -煤粉复合燃烧锅炉炉膛传热计算的基本方程 ,得到了复合燃烧锅炉炉膛传热计算的零维模型半经验法。以某 75 t/h树皮流化床 -煤粉复合燃烧锅炉为例 ,进行了炉膛传热计算。图 1表 6参According to the characteristics of fluidized bed pulverized coal combined combustion boiler, by view of the heat transfer among the fluidized bed, heat surface, flame comprehensively, the basic equation heat transfer calculation and corresponding zero dimension model (semi empirical method) have been built up in furnace of fluidized bed pulverized coal combined combustion boiler. Heat transfer calculation had been conducted for a 75t/h bark fluidized bed pulverized coal combined combustion boiler. Fig 1, tables 6 and refs 5.
