The process
Carbon black reactors, quench and main bag filters handle the product itself as a fine, adhesive dust. The main process fan after the bag filter and the dryer and conveying fans all need sealing against the dust.
The gas
Carbon black is extremely fine, adhesive and penetrating. The fan is on the clean side of a bag filter, with seals that keep the dust out of bearings and a wheel that can be cleaned.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| ID Fan | Sits at the outlet of a boiler, kiln or furnace and draws the flue gas through the plant to the stack. | Backward curved, backward inclined and radial tipped |
| Combustion Air Blower | Feeds a burner with air at the pressure the burner register needs. | Backward curved and radial tipped |
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| High Pressure Blower | Delivers combustion, aeration and conveying air where the system resistance runs to several thousand millimetres of water column in a single stage.. | Backward curved and radial tipped |
