These are the arrangement options:Īrrangement 1 – Belt Drive with an overhung impeller. Larger systems may require direct-coupled configurations while some users prefer belt-drive for speed flexibility. Forced draft fans typically call for direct-drive, Arrangement 4 fans with variable frequency drives. High-Pressure Radial Open (HPRM / HPRL)įan Arrangements indicate how the motors mount to and drive the fans.High-Pressure Radial Shrouded (HPSM / HPSL).They can require less structural support and may offer a longer mechanical life than many induced draft fans because the cleaner ambient air is not as hard on the fan as induced draft applications. Selection & Specification of Forced Draft Fansįorced draft fans accommodate high process inlet temperatures, often working to push ambient air through burners to preheat air for boiler system efficiency. However, because they are often used to feed combustion and high-temperature processes like dryers, burners, and boilers, you can be sure you’ll need forced draft fans in any or all of these industries: Forced draft fan applications are found across industries.
