Centrifugal fan technology remains at the forefront of engineering research due to its widespread application in industrial ventilation, cooling systems and environmental control. Recent ...

Fan rating tests are conducted in standardized configurations, which are rarely exactly reproduced in the field. In most actual installations, the connections between the fan and the system will have ...

When it came to choosing the three “big” boiler air fans—forced draft, induced draft and primary air—the decision revolved around efficiency. Proper air and gas flow are necessary for optimum ...

In most fan systems a single fan is selected for the required system design rating. Various methods of control are employed such as dampers, variable inlet vanes, variable pitch blades, or variable ...

Many power plants regulate fan airflow with mechanical controls, such as dampers. In some applications using fixed-speed motors in combination with dampers may not be the most energy efficient option.
