Abstract:

 To achieve the uniform distribution of fluids in furnace tubes of reaction feed heating furnaces of CCR units, this paper uses fluent software to simulate the fluids in furnace tubes of reaction feed heating furnaces. The characteristics of ∩ furnace tubes and ∪ furnace tubes in terms of flow distribution and pressure loss are obtained, and the distribution of fluids in furnace tubes under different number of furnace tubes are compared. The recommended range of the ratio of the sectional area of manifold to the total sectional area of branches is obtained, providing reference for the subsequent engineering design.

Key words: reforming reaction feed heating furnace, manifold, Fluent, flow distribution in furnace tube
