Industrial exhaust duct design.
Return duct systems.
Before discharging out the stack exhaust contamination can be reduced by filters collectors and scrubbers to maintain acceptable ai r quality.

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.
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.
Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports.

Volume velocity x area.
The goal of stack design.
9 3 pressure balancing.
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.
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.
Ivi can assist in the design of a new system or the redesign of an existing system.
Air ducts sizing air flow and required duct area.
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.
10 1 duct fittings and transitions.
The angle of the widening section must not be greater than 15º.
Our products are used to serve a variety of needs including industrial ventilation dust extraction and pneumatic conveying.

The larger perimeter also means more air will come into contact wit the material and this adds friction to the system.
