摘　　要：CFB锅炉对耐火耐磨内衬材料的性能、施工提出了严格的要求,而内衬材料的烘干过程直接关系到施工质量和材料性能。热烟气无焰烘炉法已在国内多台CFBB上运用。以一台135 MW CFBB为例,分析比较了传统木柴烘炉法与热烟气无焰烘炉法的优劣,并指出使用热烟气无焰烘炉法需注意的问题。Stringent requirements, of properties and of handling of abrasion and heat resistant lining materials, are asked for by circulating fiuidized bed boilers. The drying process of the lining material has a direct bearing on the quality of the work. Flame-free drying with hot flue gas has already been practiced on quite a number of CFB boilers. Exemplified by the case of a 135 MW CFB boiler, the advantages and disadvantages, of the traditional way of drying with timber, are analyzed, together with those of the mentioned way using flame-free hot flue gas. Problems, to which attention should paid, in case the latter way of drying is used, are pointed out.
