膜式水冷壁是大型锅炉的主要受热面之一,它具有提高炉膛的密封性能、增大幅射受热面、提高锅炉热效率、便于工地吊装和敷设炉墙等特点,因此,随着锅炉制造技术的发展,膜式水冷壁得到了广泛的应用。尤其是光管加扁钢的膜式水冷壁结构因其具有管径和节距选择灵活、鳍宽度可以调整、价格比轧制鳍片管便宜及制造工艺容易掌握等特点,而深受各锅炉制造厂的欢迎。膜式水冷壁的制造分为膜式水冷壁管排的制造、组装及弯制等几个方面,现分述如下。 1、制造膜式水冷壁的材料准备
Membrane water wall is one of the main heating surface of large boilers, which has the characteristics of improving the sealing performance of the furnace, increasing the radiant heat surface, increasing the boiler thermal efficiency, lifting the site and laying the furnace wall. Therefore, with the boiler manufacturing technology Development, membrane water wall has been widely used. Especially the light pipe plus flat steel membrane wall structure because of its diameter and pitch flexible choice, the width of the fin can be adjusted, the price is cheaper than the rolling fin tube and easy to master the manufacturing process and so on, but by the boiler Welcome to the factory Membrane water wall manufacturing is divided into film-type water wall tube manufacturing, assembly and bending and other aspects, are as follows. 1, the manufacture of membrane water wall material preparation
