火法冶炼有色金属成套设备的高温排烟热的利用,目前有各种不同的热回收装置,其中包括各种结构的余热锅炉。但由于排烟温度高,在排烟中存在大量有侵蚀性成分的杂质、其中包括对受热面和其它结构件起腐蚀作用的溶流体的飞灰(在大多数情况下是硫的氧化物)致使热回收装置结构复杂工作条件苛刻,效率不高或不能满足运行要求等。为了解决这些问题,研制了一系列统一规格的烟道式余热锅炉。这些余热锅炉具有带烟气幅射的冷却窒和屏式对流受热面的大剖面水平烟道。从而改善了受热面的工作条件,但其
At present, there are various heat recovery devices, including various structures of waste heat boilers. However, due to the high temperature of the exhaust gas, there is a large amount of aggressive components in the exhaust gas, including the dissolved fluid fly ash (which in most cases is sulfur oxide) corrosive to the heating surface and other structures, Resulting in complex structure of heat recovery device harsh working conditions, the efficiency is not high or can not meet the operational requirements. In order to solve these problems, a series of uniform specifications flue-type waste heat boiler has been developed. These waste heat boilers have a large cross-section horizontal chimney with flue gas radiation cooling chokes and screen convection heating surfaces. Thus improving the working conditions of the heating surface, but it
