Stainless Steel Membrane Wall In Boiler Tube Furnace Panel Recovery Part
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.
In order to reduce the heat loss caused by air tightness and reduce the cost of heat preservation, the modern boiler USES water wall board instead of steam generating pipe.We adopt automatic finned pipe welding machine and large pipe bending machine to make water-cooled wall plate, which can have pressing head and short welding head.We provide panel integrated manhole openings in the panel.
|Name||Membrane water panel|
|Material||Carbon steel,Alloy,Stainless steel|
|Tube size||Φ38 - 76 mm, or as required|
|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 installation workload.
