Water Wall Panels are used in modern day Boilers in place of Steam
Generating Tubes 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 Swaged
Ends, 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
|Name||Membrane water panel|

1. To guarantee the leakproofness of furnace wall and reduce the
air leak of combustion chamber.
2. To achieve the full water cooling of combustion chamber, and the
boiler accessories membrane water wall is benefit to prevent coking
under the condition of supplemental firing.
3. The thermal storage capacity is small, the warming of combustion
chamber is fast and the cooling is also fast, which could shorten
the cooling time of boiler’s start and furnace shut down.
4. It is good to adopt top supported water cooled wall and it could
reduce the load of boiler framework, which is benefit to overhang.
5. Compared with the bare tubes, the membrane water wall improves
the heat absorption capacity of tubes.
6. The factory direct boiler membrane water wall could improve the
Preliminary combination degree of boiler parts and reduce the
