摘　　要：介绍了当前节能降耗的迫切需要和转子组合式强化传热装置——"洁能芯"的技术原理。论述了2号机组甲、乙侧凝汽器性能试验内容,试验方法和试验计算结果,计算分析了安装转子组合式强化传热装置后凝汽器性能及机组经济性。安装转子组合式强化传热装置后,凝汽器端差降低2.79℃,真空提高2.97kPa,冷却水流量减小9.8%;凝汽器在相同进水温度、相同真空下,机组带负荷能力提高19.7%;凝汽器水阻增加19.52kPa。工业试验和计算分析结果表明,转子组合式强化传热装置应用于电厂凝汽器可提高其性能。Current urgent demands for energy-saving and consumption reduction were described along with the technical theory of a rotor-assembly type intensified heat-transfer device—'Clean-energy Core'. The above device has been installed on the 2# turbo-generator unit of Datang Jiamusze No.2 Power Plant. The condenser at one side of the turbo-generator unit was provided with the device in question while the condenser at another side of the unit was not. The performance test content,testing method and the calculation results of the two condensers of the No.2 power plant were discussed. The performance of the two condensers and the cost-effectiveness of the No.2 unit after installation of the device on one condenser were calculated and analyzed. After the installation of the above-cited device,the terminal temperature difference of the relevant condenser drops by 2.79 ℃,its vacuum increases by 2.97 kPa and its cooling water flow rate decreases by 9.8%. Under the condition of the condensers having the same inlet water temperature and vacuum,the load bearing capacity of the turbo-generator unit will increase by 19.7%,and the water resistance of the condensers increase by 19.52 kPa. The results of the industrial experiments and analytic calculation show that the rotor-assembly type intensified heat-transfer device can be used for condensers in power plants to improve their performance.
