Introduction of Boiler Membrane Wall

Water Walls has bare tube Water Walls and membrane water walls.

1 Membrane water wall is made of flat steel and pipe tiles welded into the airtight tube composed of water wall.
2 The bare tube water wall is composed of a row of seamless steel tubes, the structure is the most simple
3 Membrane water wall is a lot of rolling good water wall fins with spot welding welded together to make a sealed combination of heating surface, both Can improve the airtightness of the furnace, reduce the air leakage, but also protect the furnace wall, reduce the weight of furnace wall, simplify the structure.

1 Pin water wall is consisted by many pins with length 20~25mm, diameter 6~12mm welded to water wall tube.
2 And then apply chrome ore refractory plastic to reduce the amount of heat absorbed by the water wall, increase the temperature of the combustion zone, applying to the case where the fuel is particularly difficult to lignite or some liquid slagging furnace.
3 According to the layout of, there are diaphragm-type and wall attached type (that is, double-sided heating) water wall.
4 The former mostly embedded in the wall of the furnace wall, single-sided endothermic;
5 The latter in most of the large boiler in the middle of the furnace, the entire furnace divided into two separate parts, double-sided heating.


Application of Boiler Membrane Wall

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.


Additional information of Boiler Membrane Wall

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


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.
