Carbon Steel Boiler Water Wall Panel Straight Membrane Water Wall Arc Water Wall Panel for Coal-fired Boilers

The water wall was originally designed not to be heated, but to cool the furnace from high temperature damage.Later, because of its good heat exchange function, it gradually replaced the steam drum as the main heating part of the boiler.


The evaporative heating surface, which is laid on the inner wall of boiler chamber and consists of many parallel pipes.The function of water wall is to absorb the radiant heat of high temperature flame or flue gas in the furnace chamber, generate steam or hot water in the pipe, and reduce the temperature of the furnace wall to protect the furnace wall.In a large capacity boiler, the flame temperature in the furnace is very high, the intensity of heat radiation is very large.



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.

Additional


1Water wall panels are used in Waste Heat recovery boilers.
2We manufacture Water wall panels,these are fabricated out of carbon steel tubes to customers' drawings and specifications.
3Special care is taken for ovality and thinning at the bent portion,during fabrication.
4We are manufacturing and supplying a comprehensive range of Waterwall Panels.
5The 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.
6These tubes are known to provide heat uniformly that result in an increased heat output.
7The 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.

Application


1Energy 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.
2These walls form the enclosure of the coal combustion chamber.
3Water 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.
