Abstract

The invention provides an installation method of a boiler water cooling wall. The installation method comprises the following steps: 1, manufacturing a combined platform frame (1); 2, manufacturing a furnace top membrane type wall pipe (21), a front membrane type wall pipe (22), a rear membrane type wall pipe (23), a left membrane type wall pipe (24) and a right rear membrane type wall pipe (25) on the combined platform frame (1); and 3, hoisting the furnace top membrane type wall pipe (21), the front membrane type wall pipe (22), the rear membrane type wall pipe (23), the left membrane type wall pipe (24), the right rear membrane type wall pipe (25), an upper collecting box (26) and a lower collecting box (27). According to the installation method of the boiler water cooling wall, the installation production period of the water cooling wall is shortened, and the welding quality of the water cooling wall is improved.

Description

technical field [0001] The invention relates to a method for installing a water cooling wall of a boiler. Background technique [0002] The water-cooled wall is the main heating part of the boiler. It is composed of several rows of steel pipes and distributed around the boiler furnace. Its interior is flowing water or steam, and the outside receives the heat of the flame of the boiler furnace. Generally, the water-cooled wall is composed of multiple tubes. The traditional welding process scheme is to first weld the flat steel on the horizontal plane of the pipe through multi-head welding to weld the pipes into rows, and then perform manual assembly and welding. [0003] In the existing technology, 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. After welding, the water-cooled wall is easy to bend at the weld seam, causing the furnace to be not tightly sealed and ...
