摘要：介绍了T形翅片管用于重沸器中强化沸腾传热的机理及其性能特点,建立了T形翅片管重沸器设计计算模型。与HTRI计算光管重沸器相比,T形翅片管管外沸腾传热系数提高了约5倍,总传热系数提高了80.4%,重沸器面积裕量由原-26.58%增加为31.2%,工业应用证明T形翅片管重沸器很好地满足了装置提负后的生产要求,为T形翅片管重沸器工业设计提供了理论依据。
The mechanism and performance characteristics of enhancing boiling heat transfer by using T-shaped finned tubes in reboiler are introduced. Besides,the design calculation model for T-shaped finned tube reboiler is established.Compared with HTRI calculations for plain tube reboiler,the outside tube boiling heat transfer coefficient of T-shaped finned tube reboiler increases by approximate 5 times,the total heat transfer coefficient increases by 80. 4%,and the reboiler area margin increases from-26. 58% to 31. 2%. The industrial applications prove that the T-shaped finned tube reboiler meets well the production requirements of the expanded plant.This paper provides a theoretical basis for industrial design of T-shaped finned tube reboiler.
