The invention discloses a method for hoisting a radiation waste heat boiler. The method comprises the steps that S1, a plurality of central pipes are welded together according to the length of the radiation waste heat boiler; s2, a plurality of supporting pipes are welded in the radiation waste heat boiler; s3, a crane is used for slowly placing the multiple center pipes into the radiation waste heat boiler along the multiple supporting pipes, and the multiple center pipes are located in the center of the radiation waste heat boiler; s4, the upper header cover plate and the lower header cover plate are welded to the top and the bottom of the radiation waste heat boiler correspondingly; s5, a lifting lug is welded to the upper portion of the upper header cover plate; s6, the radiation waste boiler is hoisted to the needed installation position in a vertical mode through the lifting lugs above the upper header cover plate; and S7, after hoisting is completed, the multiple supporting pipes are removed. According to the method, the radiation waste heat boiler is more convenient to assemble and disassemble, convection tubes and fins in the radiation waste heat boiler are effectively protected, the welding quality of pipelines is ensured, and bending deformation in the hoisting process is prevented.

    本申请公开了一种用于对辐射废锅进行吊装的方法。该方法包括:S1,根据辐射废锅的长度,将多个中心管焊接在一起;S2,在辐射废锅的内部焊接多个支撑管;S3,使用吊车将多个中心管沿着多个支撑管缓慢放入辐射废锅的内部,使多个中心管定位于辐射废锅的中心;S4,将上集箱盖板和下集箱盖板分别焊接到辐射废锅的顶部和底部;S5,吊耳焊接到所述上集箱盖板上方;S6,利用上集箱盖板上方的所述吊耳,通过立式方式将辐射废锅吊装到所需的安装位置;以及S7,在所述吊装完成之后,移除所述多个支撑管。该方法使得辐射废锅的装拆更加方便,有效地保护了辐射废锅中的对流管与鳍片,确保管路的焊接质量,防止吊装过程中发生的弯曲变形。
