In the field of industrial ventilation and air quality, a lack of adequate analysis for aerodynamic processes, as well as a shortage of properly equipped computer facilities, has forced specialists to rely on an empirical approach to find answers in the past. Commonly based on crude models, practical data, or countertypes, the answers often offered have been imprecise.
Summarizing the results of the authors’ research conducted over the past 40 years, Industrial Air Quality and Ventilation: Controlling Dust Emissions examines air injection in granular material streams and defines the closed hood capacity widely used in the mechanical reprocessing of minerals. This book introduces a methodological approach (dynamic theory) that broadens the range of granular materials, including inter-heated material. It considers the mechanisms of ejecting air in different variations from uniform air motion processes in closed chutes to the forming of accelerated air streams in a free particles flow. It also provides the scientific basics of calculation for local exhaust ventilation dust production (aspiration), and enables readers to accurately apply these results to the mechanical processing of various materials.
• Describes the engineering methods for calculating the amounts of aspirated air for various industries and technological units
• Assists in developing new environmentally clean and competitive advanced technologies and equipment for the processing of granular materials
• Proposes new technical solutions that are more sanitary and require less energy and water consumption
• Looks at specific industry examples of localization of release
Industrial Air Quality and Ventilation: Controlling Dust Emissionsproposes low power consumption-based technical solutions and outlines more accurate methods of calculating recommended performance. Richly illustrated with practical suggestions and techniques, the text includes real-world applications in the field of aerodynamic processes within gravitational fluxes of granular material, and encourages the development of new environmentally clean and competitive advanced technologies and equipment for the processing of granular materials.

"This book summarises the results of the authors research conducted over the past 40 years. …The conclusion reminds readers that the authors original research was aimed at improving the theoretical basis for design of ventilated suction hoods used for bulk material transfer groups and then to present their basic findings and resulting conclusions."
"The book addresses the very complex topic of dust generation and fugitive emissions in industry. It provides detailed analyses, theories and data of numerous application areas — with the aim of improving the design and operation of efficient dust control systems. I have not seen such a detailed study of this complex area before, and I am confident that the book will generate a great deal of interest in both the scientific and industry communities."
—Peter Wypych, Professor, University of Wollongong
"A solid academic treatise on the evolution of dust and particulates from conveying system transfer points, with a good amount of useful data to go with the theoretical equations."
—Eric Anderson, Consulting Engineer
