摘要
研制的椭圆重力热管空气预热器具有优良的传热与空气动力学特性，已应用于石油化工厂常减压加热炉的余热回收系统，使加热炉热效率达到９０％以上。
The developed elliptic gravitational heat pipe air preheater is possessed of excellent characteristics of heat transfer and airdynamics. It has been employed in the wast heat recovery system ofheaters in atmospheric vacuum distillation unit. And the thermal efficiency of heater has been increeased up to 90%.
