Boiler Furnace Water Wall Combustion Chamber non Refractory Wall heating part
Boiler Furnace Water Wall Combustion Chamber Description
1. 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.
2. Water Wall Panels are used in modern day Boilers to reduce heat loss due to their gas tight nature and reduce insulation costs.
3. 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.
4. We supply Panels with integrated manhole openings in the panels.
5. They serve a two fold purpose here in that capture heat that would otherwise escape to the atmosphere and help heat the water in the boiler.
6. And they also help keep the refractory cool(relatively speaking)This prevents spalling of the refractory.
7. Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between.
8. These walls form the enclosure of the coal combustion chamber.
9. 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.
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.
