大型锅炉的炉室横截面尺寸较大,需要增强炉室受热面(包墙过热器、水冷壁)部件的横向刚度,一般都设计有刚性梁加固装置。锅炉正常运行时,这种刚性梁装置可以减弱由于炉膛燃烧工况变化而引起的受热面部件的震动;另外,一旦炉膛燃烧发生爆炸时,它 The cross-section size of the furnace chamber of a large-scale boiler is large, and it is necessary to enhance the lateral rigidity of the heating surface (wall superheater, water-cooled wall) components of the furnace chamber. Generally, a rigid beam reinforcement device is designed. When the boiler is in normal operation, the rigid beam device can reduce the vibration of the heating surface parts caused by changes in the combustion conditions of the furnace; in addition, once the furnace burns, it will explode.
