Membrane Water Wall Panels For Power Station, Painted Carbon Steel SA210 A1
Product Introduction
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.
Description: Membrane Water Wall
Water wall panels are used in Waste Heat recovery boilers. We
manufacture Water wall panels. These are fabricated out of carbon
steel tubes to customers' drawings and specifications. Special care
is taken for ovality and thinning at the bent portion, during
fabrication.
We are manufacturing and supplying a comprehensive range of
Waterwall Panels. The tubes offered by us are known to withstand a
great internal pressure as a continual strip of fin material is
wound spirally on the tube. These tubes are known to provide heat
uniformly that result in an increased heat output.
The main function of water wall panels in boiler is to absorb the
heat generated by high temperature flame or flue and to generate
steam or hot water in tubes, hence to reduce the temperature in the
chamber.
Advantages of Membrane Water Wall
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
installation workload.

Application
1 | Energy saving enviromental protection china supplier membrane water wall for CFB boiler are membrane walls that are made of tubes welded together with or without a strip of metal in between. |
2 | These walls form the enclosure of the coal combustion chamber. |
3 | 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. |
Note
1 | Control of weld penetration to satisfy mechanical and heat transfer requirements Control of the deformation to acceptable tolerances. |
2 | Panels routinely require straightening in the workshop after welding and heat treatment, the question to be answered is can the shop then meet the required dimensional tolerances for successful site installation? |
3 | Can existing shop handling procedures be used as-is without adding excessive controls that will add cost and schedule. |
4 | The importance of preheating and its maintenance through the welding process could cause a number of handling and shop processing issues that will substantially increase cost. |
