Cyclones and Multi Cyclones

Used for collection of coarse dust particles. Our cyclones are effectively designed to remove dust with an emission level of 200 mg/m 3 . The pressure drop across the cyclones are as low as 50-100 mm WG resulting in energy savings. For high dust loading condition they act as primary filtering system before the bag filter. They do not require any maintenance.

Multicyclones are offered to handle larger volumes of hot gas and to achieve better emission standards. Mostly used for flue gas filtration from Boliers, Kilns etc. where the operating temperature is high and the particulate is of abrasive nature.

These high efficiency cyclones are frequently used as product receivers, as precleaners to high efficiency fabric-type dust collectors, or as independent collectors for coarse dusts.

• Stable pressure drop for a given gas flow
• Constant efficiency for a given particulate condition
• No moving parts; no replaceable filters
• Ability to handle extremely high dust concentration

On industrial coarse particulate, FD Cyclones are 95% to 98% efficient. Efficiency is a function of the physical parameters of the application and the design parameters of the cyclone. Cyclone efficiency increases with:

• Coarse particle size distribution
• Higher product specific gravity
• Lower gas density
• A decrease in cyclone diameter (two smaller cyclones in parallel will have a higher efficiency than one larger cyclone with an equal pressure drop)
• Smaller outlet diameter. An increase in pressure drop also results.

Efficiency and pressure drop are also affected by barrel length, outlet length, inlet configuration, and design of the internal cone. These factors are optimized to result in the maximum possible efficiency at a practical overall size and pressure drop.

The FD cyclone optional components include discharge hopper, scroll outlet and steel support legs. Common hoppers and scroll outlets are available for multiple cyclone configurations.
