Embodiment Construction

[0017] Below in conjunction with accompanying drawing and specific embodiment the invention is further introduced:

[0018] refer to figure 1 and image 3 , a method for preventing deformation of a water wall assembly, said method comprising the steps of,

[0019] S001. Weld the water-cooled wall on the ground, and fix and connect the water-cooled wall 1 to be hoisted by welding;

[0020] S002. Welding and installing the water-cooled wall, hoisting the water-cooled wall 1 to a high place and fixedly connecting it to the place to be installed by welding.

[0021] The present invention avoids the complex environment of high-altitude welding operation by first welding on the ground and then hoisting and installing, makes the welding simple and efficient, and avoids the bending of the weld seam between the water-cooled walls caused by the hoisting and welding of the water-cooled walls 1. The implementation method of the present invention is simple, and can greatly reduce the be...

Abstract

The invention discloses a method for preventing deformation of a water-cooled wall assembly piece. The method comprises the following steps of S001, welding water-cooled walls on the ground, wherein aplurality of water-cooled walls which need to be suspended are fixedly connected through welding; S002, conducting welding installation on the water-cooled walls, wherein the water-cooled walls are suspended into a hearth and fixedly connected to positions, where the water-cooled walls are about to be installed, in the hearth through welding. By means of the method, the problem in the prior art that after welding, the water-cooled walls are easily curved at welding joints, thus sealing of the hearth is not tight, and then smoke is leaked is solved.

Description

technical field [0001] The invention relates to the field of electric power generation, in particular to a method for preventing deformation of a water-cooled wall assembly. Background technique [0002] The water wall is the main heating part of the boiler, which is composed of several rows of steel pipes and distributed around the boiler furnace. Its inside is flowing water or steam, and the outside receives the heat of the flame in the boiler furnace. It mainly absorbs the radiant heat of the high-temperature combustion products in the furnace, and the working medium moves up in it, and evaporates when heated. [0003] The installation of the water-cooled wall has always been hoisted first and then welded. During welding, the water-cooled wall is hoisted in mid-air for welding. Due to the complicated and difficult-to-control high-altitude operation environment, the water-cooled wall is easily bent at the weld seam after welding, resulting in a loose furnace seal. to the...
