Membrane Water Wall Tubes For Utility / Power Station Boiler , Alloy/SS/CS Steel
Product Description
A waterwall in a boiler is an furnace wall that is comprised of refractory and tubes in a water-tube boiler.The tubes are evenly spaced and generally connect to headers which in turn are connected back to the main generating bank of the boiler.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.And they also help keep the refractory cool(relatively speaking)This prevents spalling of the refractory.
The membrane water wall refers to the water wall formed by the air
- tight tube screen welded by flat steel and pipe.The membrane water wall can ensure good tightness of the furnace,
significantly reduce the air leakage coefficient of the furnace and
improve the combustion condition in the furnace.It can increase the effective radiated heat area, thus saving the
steel consumption.
Types
1.gas shielded arc welding
2.submerged-arc welding
Advantage
1. the membrane water cooling wall has the most thorough protective effect on the furnace wall. Therefore, the furnace wall only needs insulation material instead of refractory material, which greatly reduces the thickness and weight of the furnace wall, simplifies the structure of the furnace wall and reduces the total weight of the boiler.
2.the membrane water wall also has good air tightness and can adapt to the requirements of positive pressure combustion on the boiler. It is not easy to slag formation and air leakage. It can reduce the heat loss of exhaust smoke and improve the thermal efficiency of the boiler.
3.the components can be welded by the manufacturer, and the installation is quick and convenient.
4. the boiler with membrane wall structure is convenient and simple in maintenance, and the service life of the boiler can be greatly improved.

Application
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.
