Abstract

Pneumatic conveying technology, as an efficient material transportation method, has been widely used in various industrial fields. To study the powder transportation in horizontal ash conveying pipes, this study relies on the Computational Particle Fluid Dynamics (CPFD) numerical method. The characteristics of the gas-solid two-phase flow under continuous air supply conditions are analyzed, and the effects on particle movement of factors such as feed port spacing, inlet air velocity, and the number of discharge ports are explored accordingly. The research results show that when the inlet velocity is 5 m/s, adjacent discharged particles come into contact after 8 s. As the inlet air velocity increases, the contact time between adjacent discharge ports is shortened. When the feed port spacing increases from 0.5 to 2 m, the dust accumulation thickness decreases by about 0.6 times. Additionally, when the spacing reaches a certain value, the rate of decrease in dust accumulation thickness begins to diminish.
