Industrial Exhaust Duct System Design: Fundamental Concepts

OSHA, WHO and other organizations educate the health hazard associated with contamination in the environment and specify the contaminant presence in air at works place, residential and other special environments like cinema theaters, hotel rooms etc. To maintain indoor air quality and to protect the personnel exposed to various aerial contamination is becoming essential part of industries, malls, theaters etc. and wherever the contamination is beyond acceptable limit, it is essential to install systems to capture the contamination, transport to a cleaning unit and through the cleaned air out to atmosphere or send back. Correct suction and static pressure requirements are to be maintained and balanced in any pollution control system for efficient capture and conveying of contaminants. Energy efficiency is a important criteria and employing a oversized fan or a incorrect operating point will lead to tremendous loss of energy or inefficient air purification. A through understanding of fundamental principles is essential for designing a energy efficient and good performing duct system. This book is intended to serve this purpose.
