本文论述了链条锅炉拱的设设中如何采用新型耐火材料,铝酸盐耐火混凝土,在设计结构中应解决的关键矛盾和对策。作者提出的具体结构。经长期运行考证,这一结构是成功的。实践证明,它具有工艺简单,具有整体性、寿命长、维修方便、节约烧制耐火砖的能源,支吊异形耐火砖的金属吊挂件可以简化,使锅炉更加紧凑。 This article discusses how to adopt new refractory materials and aluminate refractory concrete in the design of chain boiler arch. The key contradictions and countermeasures should be solved in the design of the structure. The specific structure proposed by the author. The long run research, this structure is successful. Practice has proved that it has the advantages of simple process, integrity, long service life, convenient maintenance, energy conservation of fired refractory bricks, metal hanging parts for supporting irregular shaped bricks, and more compact boiler.
