Theory and Design of Dilute Phase Pneumatic Conveying

This article describes the theory and calculation method for de-signing dilute phase pneumatic conveying systems. It is based on the work of Dr. F.A. ZENZ and Dr. D.F. OTHMER as described by them in their book "Fluidization and Fluid-Particle Systems" published in 1960 (Ref. 1). This method was later modified by

Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.

SIZING A PNEUMATIC CONVEYING SYSTEM

As a general rule in pneumatic conveying, when sizing a system we look primarily at pressures, velocities and line loadings to determine best what the line size should be. For example a well sized dilute phase pressure system going 200 feet would probably run somewhere between 6-12 PSIG, have a terminal velocity of between 4,500 – 6,000 fpm
