Carbon Steel Or Alloy Steel Membrane Water Wall Panels In Boilers furnace wall
Carbon Steel Or Alloy Steel Membrane Water Wall Advantages
1. Ensure the sealing of furnace,reduce air leakage fo furnace chamber.
2. Realize full water cooling in the combustion chamber, which is conducive to preventing coking under the condition of intensified combustion.
3. Low heat storage capacity, fast heating and cooling of the combustion chamber, which can shorten the cooling time of the boiler starting and stopping.
4. It is suitable to use tube-laying furnace wall, which greatly reduces the load of boiler frame and facilitates suspension.
5. Compared with the light pipe, the heat absorption capacity of the pipe is improved.
6. Improve the pre-assembly degree of boiler components, facilitate and reduce the installation workload.
Boiler Membrane Water Wall Discription
1. Dehai Boielr manufacture membrane water wall panels with submerged arc welding machine.And it usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.
2. It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling and protection of the furnace wall, so the name.
3. 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.
4. In a large capacity boiler, the flame temperature in the furnace is very high, the intensity of heat radiation is very large.Forty to fifty percent or more of the heat in the boiler is absorbed by the water wall.Except for a few small capacity boilers, modern water tube boilers take water cooling wall as the main heating surface of evaporation.
Advantages
1. The protective effect of membrane water cooling wall on the furnace wall is the most complete, so the furnace wall only needs insulation materials, rather than refractory materials, so that the thickness and weight of the furnace wall are greatly reduced, simplify the structure of the furnace wall, reduce the total weight of the boiler.
2. Membrane water wall also has good air tightness, can adapt to the requirements of positive pressure combustion on the boiler, not easy to slag formation, less air leakage, reduce the heat loss of smoke exhaust, improve the boiler thermal efficiency.
3. it can be welded into components by the manufacturer for quick and convenient installation.
4. the use of membrane wall structure of the boiler, simple maintenance, boiler service life can be greatly improved.
