摘要
针对ASM-600进口油站换热器存在换热裕量偏小的现状,对其国产化替换并进行提升传热性能的改进。从理论上运用传热效率-传热单元数法,分别核算改进前后的温降值,通过投运实践并对比,证实了该换热器国产化改进实施的可行性,可为同类型设备加速国产化步伐,提供借鉴和参考。
In view of the small heat transfer margin of ASM-600 imported oil station heat exchanger,this paper,the localization replacement and improvement of heat exchanger performance is introduced.In theory,the method of heat transfer efficiency and number of heat transfer units(ε-NTU)is used to calculate the temperature drop before and after the improvement.The feasibility of localization improvement of the heat exchanger is verified through operation practice and comparison,which provides reference and reference for similar equipment to accelerate the pace of localization.
