Power Plant Furnace wall Membrane Water Wall Argon-arc Welding
Product Description of Membrane Water Wall
We are manufacturing and supplying a comprehensive range of Waterwall Panels. 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. These tubes are known to provide heat uniformly that result in an increased heat output.Water wall panels are used in Waste Heat recovery boilers. We manufacture Water wall panels. These are fabricated out of carbon steel tubes to customers' drawings and specifications. Special care is taken for ovality and thinning at the bent portion, during fabrication.
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.
(1) membrane type water cooling wall of the furnace wall protection is the most thorough, so the furnace wall only need to use insulation materials, rather than refractory materials, so that the thickness of the furnace wall, weight are greatly reduced, simplify the furnace wall structure, 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 slagging, less air leakage, reduce the heat loss of smoke exhaust, improve the thermal efficiency of the boiler.
(3) The assembly can be welded by the manufacturer to leave the factory, quick and convenient installation.
(4) the use of membrane wall structure of the boiler, convenient and simple maintenance, the service life of the boiler can be greatly improved.
Advantages
1.ensure sealing of furnace wall and reduce air leakage in combustion chamber.
2.realize full water cooling of the combustion chamber, which is helpful to prevent coke formation in the case of intensified combustion.
3.small capacity of heat storage, fast heating of combustion chamber and rapid cooling, can shorten the cooling time of boiler start and stop.
4.it is appropriate to use pipe furnace wall, which greatly reduces the load of boiler frame and is convenient for suspension.
5.compared with the optical tube, the heat absorption capacity of the tube is improved.
6.the pre-combination degree of boiler components is improved, which is convenient and reduces the installation workload.

Waterwall Panel Workshop
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. |
