真空式相变传热热水器工作原理及实用热力计算

Operating Principle of Vacuum Phage Transition Heat Transfer Water Heater and the Heat Calculation Method

本文讨论了工业炉窑排烟余热回收的最新技术──真空式相变传热热水器的工作原理。具有结构简单、安全可靠、能在小温差下获得较大的传热特点。结合２Ｔ／Ｈ蒸汽锅炉回收其尾部排烟余热实例，给出了热力计算方法。该方法适用于一般真空式相变传热热水器的热力计算，简单实用且可保证精度。

This paper has a prelimnary analysis to the operating principle of Vacuum Phase Transition Heat Trans fer Water Heater(VPTHTWH) which is the newst technique of exhaust flue waste heat recovery to beused in the industrial furnace and boiler.VPTHYWH has many advantages in comparison with other flue waste heat recovery equipment,such as simple structure,safety,teliable.It can transfer the greater amount of heat with fewer thermal difference.According to the heat recovery example for the trailer flue waste heat of 2T/H steam boiler,the paper shows us a heat calculation method,which is suitable for the general VPTHYWH heat calculation The method is both useful and exact.
