Steel Boiler Water Wall Tubes Auto Submerged Welding, ASME Standard

Product Description of Water Wall Panel

Water Wall Panels are used in modern day Boilers to reduce heat loss due to their gas tight nature and reduce insulation costs. We fabricate Water Wall Panels using automatic Fin to tubes welding machines and large Tube Panel Benders to achieve desired shape of panels which can have Stub Welded to Headers. We supply Panels with integrated manhole openings in the panels.

Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.

Parameter of Water Wall Panel

Features of Water Wall Panel

1. Strength calculation report with applied materials information;
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;
4. Hydraulic test report: ensure the standard working pressure and safety.

Advantages of Water Wall Panel

1.ensure the sealing of furnace wall and reduce air leakage in combustion chamber.

2.realize full water cooling in the combustion chamber, which is conducive to preventing coking under the condition of intensified combustion.

3.low heat storage capacity, fast heating and cooling of the combustion chamber, which can shorten the cooling time of the boiler starting and stopping.

4.it is suitable to use tube-laying furnace wall, which greatly reduces the load of boiler frame and facilitates suspension.

5.compared with the light pipe, the heat absorption capacity of the pipe is improved.

6.improve the pre-assembly degree of boiler components, facilitate and reduce the installation workload.
