Heavy Industry Blowers
By: susana terlicki
Boiler fans create efficient combustion by supplying a consistent and reliable ait flow. Induce Draft Fans (I.D. Fans) operate at elevated temperatures and draw the air stream through the combustion chamber, then push it through pollution control equipment. Forced Draft (F.D. Fans) or Combustion Air Fans push the air stream into the boiler combustion chamber. Multi-Fuel Burning Power Boilers are used to create steam for different power needs. Induced Draft Fans are typically AMCA arrangement 3, single or double inlet with inlet box(es). Wheels often require abrasion resistant construction with radial tip or backwardly curved blades. Combustion Air FD Fans are typicallyconstructed of carbon steel, and utilize airfoil or backward inlined blade design. Common AMCA arrangements for combustion air fans are arrangement 3 and 8, both with inlet vane or outlet damper control.(read

Industrial Ventilation With Blowers And Fans
By: susana terlicki
Process fans include several types such as duct fans, roof and ceiling ventilators, wall mounted fans, pressure blowers, and freestanding units with different mounting options. For extreme conditions and plants, drum fans can be used to move even larger amounts of air. These types of fans come with wheels attached and can be rolled to the area that circulation is needed the most. Some manufacturers even sell just the fan heads for a more freedom and a reduced assembly and cost on the company.(read

High Temperature Fan And Blower
By: susana terlicki
There are two major types of high temperature fans - centrifugal and axial:
Centrifugal Wheels:
* Multiblade forward curve wheel. This type of wheel is usually specified where there is a necessity for large volumes of flow against low to medium static pressure requirements. The forward curve blade is that it delivers the same volume of air as either the backward or radial blade wheel, at a lower fan speed, which is important due to wheel stresses at elevated temperatures. This fan is the most common type used in all types of heat treatment operations except where a buildup of material on the blades could occur, as wheel unbalance would result.
* Radial Blade, paddle wheel type fans. This type of wheel is usually specified where there is a necessity for medium volumes of flow against medium to large static pressures. The paddle wheel is considered a self cleaning type of wheel. It could be used where there are various materials or dust in the air stream. Due to its structurally strong design, it is used in many heat treatment applications at very high temperatures where maximum fan longevity is desired.
Axial Blade Wheels:
* The axial blade wheel is usually specified where there is a need for very large volumes of flows against low static pressure. Axial wheel like the multi-blade forward curve type wheel could cause an axial fan to deliver different air volumes at the same static pressure, if the total pressure requirement of the fan system was underestimated. This type of fan is ideally suited where a large volume of flow is required with a minimum of duct work and is used extensively for small and large furnaces, such as aluminum annealing.(read

Engineering Of High Temperature Axial Fans
By: susana terlicki
Ventilators with ambient air cooling systems handling hot airstreams must have sufficient airflow and be kept in operation until airstream temperatures cool below 120 F to prevent damage to the fan unit. The Tubeaxial fan ambient air cooling system is only effective while fan is operating.(read

Force Draft Fan And Blower
By: susana terlicki
Factors in the design of ventilation systems include the flow rate (which is a function of the fan speed and exhaust vent size) and noise level. If the ducting for the fans traverse unheated space (e.g., an attic), the ducting should be insulated as well to prevent condensation on the ducting. Direct drive fans are available for many applications, and can reduce maintenance needs.(read

Centrifugal Vs. Axial Fan
By: susana terlicki
Variable pitch wheels in axial fans and blowers are used where precise control of static pressure within supply ducts is required. The fan wheel will spin at a constant RPM . The blades follow the control pitch hub. As the hub moves toward the rotor the blades increase their angle of attack and an increase in flow results.(read

Industrial Blowers And Fans From Fans Mall
By: susana terlicki
Fans and ventilators are classified into propeller, tube axial and vane axial styles, and each type has different characteristics. Propeller fans consist of only a motor and propeller and therefore are the simplest. Tube axial are similar to propellers but has a venturi around the propeller to reduce the vortices. Vane axial fans are equipped with vanes that trail behind the propeller in the airflow to straighten the swirling flow.(read

Centrifugal Blowers From Fans Mall Co
By: susana terlicki
A centrifugal blower has a number of blades mounted around the hub, which turns on a shaft that passes through the housing. The gas enters the side of the fan wheel and by use of centrifugal force (hence the name) accelerates over the fan blades. A centrifugal blower is usually used in factories or large open places that need air flow.(read

Centrifugal Fan And Axial Ventilators
By: susana terlicki
Airfoil Centrifugal Fans are used for airstreams where high efficiency and quiet operation are required. They are used extensively for continuous service at ambient and elevated temperatures in forced and induced draft applications in the metals, chemical, power generation, paper, rock products, glass, resource recovery, incineration and other industries throughout the world.(read
