Water Wall Tube: These are tubes in the Boiler where water is
evaporated to steam and are also called Steam Generating Tubes.
These Tubes also form the Walls of the Boiler and are hence called
Water Walls or Water Wall Panels. These Tubes have very complicated
shapes to allow Inspection openings and burner throats and
fabrication require intricate binding on CNC programmable bending
Machines and checking on 3D layouts.
|Name||Membrane water panel|
|Material||Carbon steel,Alloy,Stainless steel|
|Tube size||Φ38 - 76 mm, Customize|
|Standard||ISO , ASME|
|Application||Istallable around the boiler combustion chamber|
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
