Abstract: 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.
Key words:  T-shaped finned tube    reboiler    calculation model    boiling heat transfer enhancement    exchanger design
