介绍一种新型节能燃油回油冷却系统 ,该系统与现有的水冷却燃油回油冷却系统相比 ,具有节能显著、配套设备少、运行操作简单、系统的经常性维护和检修工作量少及运行费用低、占地面积小、对环境无污染等优点。该系统已在上海外高桥发电厂建成 ,并投入使用 ,现场测试表明 ,系统运行正常、冷却效果好 This paper introduces a new energy-saving fuel oil-return cooling system. Compared with the existing water-cooled fuel oil-return cooling system, this system has the advantages of significant energy saving, less auxiliary equipment, simple operation and operation, less regular maintenance and overhauling of the system and Low operating costs, small footprint, no pollution to the environment and so on. The system has been completed in Shanghai Waigaoqiao Power Plant and put into use, field tests show that the system is operating normally, the cooling effect is good
