本文介绍了高效换热热管换热器在蒸汽机车锅炉的排烟中进行余热回收和应用的方案及其应用的意义。应用热管换热器后对提高蒸汽机车锅炉热效率进行了初步计算,并与热管换热器在DK_1型蒸汽机车锅炉上应用获得的实验数据进行了比较。最后,介绍了应用热管换热器后蒸汽机车锅炉热效率和其它几项指标提高的数值,以及该设备应用的回收年限等。 This paper describes the efficient heat exchanger heat pipe heat exchanger in the steam locomotive boiler exhaust heat recovery and application of the program and its significance. After the application of the heat pipe heat exchanger, the thermal efficiency of the steam locomotive boiler was preliminarily calculated and compared with the experimental data obtained from the application of the heat pipe heat exchanger on the DK_1 steam locomotive boiler. Finally, introduced the heat pipe heat exchanger after the heat efficiency of steam boiler and several other indicators to improve the value, as well as the recovery time of the device application.
