PNEUMATIC CONVEYING: Optimal System Design, Operation and Control

摘要

Pneumatic conveying is a ubiquitous mode of conveying bulk solids in a wide range of industries, including chemicals, plastics, grain, food, agricultural, mining, power and cement. In recent years, the capacities, distances and variety of materials to be conveyed have increased, often approaching the design limitations of the available hardware. In addition, energy-efficiency considerations require designing pneumatic conveying systems closer to the theoretical limit. Meanwhile, the operational reliability and stability of dense-phase systems have been significantly enhanced through the application of sophisticated air-control systems. This article outlines some of the underlying concepts for optimal design and operation of both dilute-and dense-phase pneumatic conveying systems.
