Industrial exhaust duct design.

10 3 fire and smoke dampers. Air ducts friction loss diagram a major loss diagram for air ducts imperial units ranging 10 100 000 cfm. Duct system design guide first edition 2003 mcgill airflow corporation mcgill airflow corporation one mission park groveport ohio 43125 duct system design i notice. The angle of the widening section must not be greater than 15º.

Ductwork made easy us duct an american manufacturer of industrial ducts and industrial ductwork solutions focuses on delivering quality products quickly and at the best price. The goal of stack design. 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. Ivi can assist in the design of a new system or the redesign of an existing system.

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. 10 4 diffusers grilles registers. Installing engineering controls is the preferred method of. Volume velocity x area.

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. Friction in a system means the fan needs to work harder and this results in higher operating costs. 9 2 central return. Our products are used to serve a variety of needs including industrial ventilation dust extraction and pneumatic conveying.

Air ducts velocity diagram air flow volume duct size. Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports. Before discharging out the stack exhaust contamination can be reduced by filters collectors and scrubbers to maintain acceptable ai r quality. 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.

No part of this work may be reproduced or used in any form or by any means graphic electronic or mechanical including photocopying. 10 2 volume control dampers. 9 1 distributed return. Air ducts sizing air flow and required duct area.

The larger perimeter also means more air will come into contact wit the material and this adds friction to the system. 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. Duct fittings and terminal units. Ivi s engineering and design team has years of experience designing and sizing industrial ductwork.

The rectangular duct therefore requires more metal for its construction this adds more weight and costs to the design. 10 1 duct fittings and transitions. Return duct systems. 9 3 pressure balancing.
