The angle of the widening section must not be greater than 15º.

Industrial exhaust duct design.

Volume velocity x area. Duct systems include straight lengths or sections of duct transitions elbows and bends enlargements or contractions hoods discharge stacks and hangers or supports. 10 2 volume control dampers. Our products are used to serve a variety of needs including industrial ventilation dust extraction and pneumatic conveying.

Air ducts friction loss diagram a major loss diagram for air ducts imperial units ranging 10 100 000 cfm. The rectangular duct therefore requires more metal for its construction this adds more weight and costs to the design. Installing engineering controls is the preferred method of. The goal of stack design.

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. Air ducts sizing air flow and required duct area. Friction in a system means the fan needs to work harder and this results in higher operating costs. Air ducts velocity diagram air flow volume duct size.

10 1 duct fittings and transitions. 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. 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.

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.

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. Design of ducts with side junctions side duct junctions. 9 3 pressure balancing.

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.
