Abstract

Abstract

Instability of horizontal pneumatic conveying system was recognized through analyzing the wave of solid mass flowrate and pressure fluctuation during transportation of solids. Furthermore, an empirical correlation for critical conveying velocity of fine and medium size particles (d_s<0.5mm) under high solids loading (range from 30 to 150) at low gas velocities less than 15m/s was proposed.
