Product Description of Membrane Water Wall
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.
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.
Membrane water wall is an air-tight structure consisting of pipes and fins.The advantages are less air leakage in furnace; can use pipe-laying wall, less load on steel structure and lower cost of boiler; easy to use suspension structure and improve thermal expansion system, suitable for large-scale mechanized production, high assembly rate, low heat storage capacity and shorten star-up and shutdown time. The disadvantage is that the manufacturing process is complex. Membrane water wall is often used in large capacity, high temperature and high pressure boilers.
According to the different manufacturing process, the membrane water wall can be divided into three types(see Fig. 1):1.rolled fin tubes are welded in rows, with less welding workload, but the fin tubes are expensive. 2.bare tube and fin(flat steel) are welded in rows, which has low material cost and can easily meet the requirements of various pitches, but flat steel requires high precision and finishing equipment.3.Bare tube fusion welding,the fins between tubes are formed by filling the welding wire, mostly used for the small pitch between the tubes. The pitch between tubes of membrane water wall is related to factors such as boiler pressure and furnace heat load, usually s/d is 1.2-1.5.
