Suggestionss For Building Ventilation And Cooling
By: oleg tchetchel
Practical methods of plants ventilation and cooling are:
* Exhaust fans or Power Roof Ventilators (PRVs).
To do a satisfactory job of eliminating excessively hot air, it is usually essential to have powered wall and/or roof exhausters. These fans should also help to control air pressure within the building whether it be negative or positive pressure.
* Supply Fans or PRVs.
A large number of buildings use exhaust PRVs to exhaust fumes, smoke, dust or other contaminants unavoidable in the operation of the business. As a result, these buildings are frequently under a severe negative pressure. The solution to the problem of this kind is usually found in the use of supply fans or "make-up" air ventilators.
* Air Circulators.(read

Industrial Process Blowers And Fans
By: oleg tchetchel
Hydrogen Sulfide is a major contaminant - a source of sulfur. In high concentrations it can be lethal. It occurs in natural gas, oil, volcanic emissions, and some mineral springs. In oil refining processes its presence is undesirable, and it must be removed. The Clause process is one of the methods used to remove the hydrogene sulphide, and while doing so, recover elementar sulfur.(read

Radial Blowers Fans
By: oleg tchetchel
Blowers can have higher output pressures, but not a lot higher and they lose capacity rapidly with increasing pressure. In centrifugal fan, as opposed to axial flow fan, the air is moving perpendicularly to the fan shaft. Often called a "squirrel cage" (due to its similarity in appearance to exercise wheels for pet rodents), the centrifugal fan has a moving component (called an impeller) that consists of a central shaft about which a set of blades, or ribs, are positioned. Centrifugal fans blow air at right angles to the intake of the fan, and spin the air outwards to the outlet (by deflection and centrifugal force). The impeller rotates, causing air to enter the fan near the shaft and move perpendicularly from the shaft to the opening in the scroll-shaped fan casing. A centrifugal fan produces more pressure for a given air volume, and is used where this is desirable such as in leaf blowers, hair driers, air mattress inflators, inflatable structures, and various industrial purposes. They are typically noisier than comparable axial fans. A mixed flow fan is an air moving device in between axial flow fan and centrifugal fan. Mixed Flow fans are an excellent choice for return air, supply, or general ventilation applications where low sound is critical. As compared to similarly sized tubular centrifugals and vane axials, a mixed flow fan will be 5-20 dB quieter! In addition, the mixed flow wheel is extremely efficient and will cut down on operating expenses.(read
