(一) 在高炉冶炼中,常规间壁式换热器传热能力低,流路阻损火,经济效益差,热风炉的烟道废气经烟囱放散,大量余热未能利用。从七十年代末起,高效等温传热元件的应用很快从空间技术领域引向工业民用建设。因它具有构造简单、制造容易、传热能力高、重量轻、体积小、流阻低、密封性好等优点,被国内外公认为先进的余热回收装
(A) In the blast furnace smelting, conventional heat exchanger wall heat transfer capacity is low, the flow resistance of fire damage, poor economic efficiency, stove flue gas emissions through the chimney, a large number of waste heat can not be used. From the late seventies, the application of efficient isothermal heat transfer components quickly led from the field of space technology to industrial civil construction. Because it has the advantages of simple structure, easy manufacture, high heat transfer capacity, light weight, small volume, low flow resistance, good sealing, etc., it is recognized as advanced waste heat recovery equipment at home and abroad
