110kW 热管换热器设计摘 要近年来，我国经济转向高质量发展阶段，对于环境的约束日趋严格，在节能减排等方面取得了一定的进展和成效，未来国家将继续推进环保政策，改善生态环境，维持我国经济运行的平稳增长。重力热管换热器作为一种高效的换热设备，具有无需外加动力、传热效率高、运行安全性强、制造工艺简便、生产成本低廉、后期维护方便等优点，尤其适用于对电站锅炉烟气余热的回收再利用，响应国家的节能减排政策。因此根据某燃煤电站锅炉的工程实际工况参数，采用常规设计计算法，设计一台可用于烟气余热回收并且采用 H 型翅片的重力热管换热器。在换热器与烟气和空气的换热过程中，对温度、热量、阻力等传递过程中进行了较为细致的设计计算，对重力热管换热器本身安全性进行了严格的校核，并对其进行了简单的经济性分析，从理论上系统地论证了重力热管换热器性能方面的高效性、结构方面的安全性和运行方面的经济性。关键词：重力热管；H 型翅片；设计；余热回收Design of 110 kW gravity heat pipe heat exchanger AbstractIn recent years, China's economy turned to a stage of high-quality development. The constraints of environment will become increasingly strict. China has made some progress and achievements. In the future, China will go on promoting environmental protection policies to improve ecological environment. Furthermore, it can keep the steady growth of China's economic operation. As an efficient heat exchanger, gravity heat pipe heat exchanger has the advantages of no additional power, high heat transfer efficiency, strong operation safety, simple manufacturing process, low production cost and convenient maintenance. It is especially suitable for the recovery and reuse of waste heat from boiler flue gas in the power station. Besides, it responds the national policy of energy conservation and emission reduction. Therefore, according to the actual working condition parameters of a coal-fired power plant boiler, a gravity heat pipe heat exchanger with H type fins, which...
