T形系列翅片管在大温差重沸器上的应用研究

Application of T-shaped serial finned tubes in reboiler with large temperature difference

结合石油化工企业重沸器技改实例,将T形系列翅片管应用于大温差传热重沸器中,并对T形系列翅片管重沸器进行工业试验研究。结果表明,改进后的T形翅片管———TXY形翅片管重沸器可解决传统的重沸器传热温差大、易结垢的问题。

Combined with the technical reconstruction of reboilers used in petrochemical enterprises, the T-shaped serial finned tubes were used in reboilers with large temperature difference. Some industrial tests on reboilers of T-shaped serial finned tubes were made. Results indicate that the reconstructed T-shaped finned tubes, namely TXY-shaped finned tubes, may resolve problems such as large heat-transfer temperature difference, and deposited easily in conventional reboilers.
