Industrial Exhaust Duct Design

The goal of stack design.

Industrial exhaust duct design.

10 3 fire and smoke dampers. Ivi s engineering and design team has years of experience designing and sizing industrial ductwork. Before discharging out the stack exhaust contamination can be reduced by filters collectors and scrubbers to maintain acceptable ai r quality. 9 1 distributed return.

Ivi can assist in the design of a new system or the redesign of an existing system. 9 3 pressure balancing. Air ducts velocity diagram air flow volume duct size. The larger perimeter also means more air will come into contact wit the material and this adds friction to the system.

10 4 diffusers grilles registers. Volume velocity x area. 9 2 central return. Exhaust stack and air intake design strategies stack design strategies the dilution a stack exhaust can pr ovide is limited by the disper sion capability of the atmosphere.

Upon a final understanding of the exhaust volume the contaminants being collected and the velocity requirements sizing the ductwork for an industrial ventilation system can be determined with the flow rate equation q va. No part of this work may be reproduced or used in any form or by any means graphic electronic or mechanical including photocopying. Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports. Friction in a system means the fan needs to work harder and this results in higher operating costs.

Installing engineering controls is the preferred method of. Wood shops and paint spray booths. Duct system design guide first edition 2003 mcgill airflow corporation mcgill airflow corporation one mission park groveport ohio 43125 duct system design i notice. This is a general introduction to the design of industrial ventilation systems with an additional discussion of two of the more common industrial ventilation applications.

10 2 volume control dampers. Duct fittings and terminal units. A side duct should join the main one at a tapered progressive widening and at an angle of 30º or less recommended or up to 45º or if there is insufficient space. The rectangular duct therefore requires more metal for its construction this adds more weight and costs to the design.

Air ducts sizing air flow and required duct area. 10 1 duct fittings and transitions. Return duct systems. Ventilation systems for ventilation and air handling air change rates ducts and pressure drops charts and diagrams and more.

Industrial duct systems are used for supply or exhaust are under positive or negative pressure of heavy or light duty construction convey clean and dirty airstreams constructed of metal plastic or fabric materials and assembled together with flanges clamps slip fit or welded. Our products are used to serve a variety of needs including industrial ventilation dust extraction and pneumatic conveying. The angle of the widening section must not be greater than 15º. 8 7 rules of duct design acca manual d residential duct systems 9 0.
