The process
Cold rolling and annealing lines emit oil mist at the mill stands and fume from the cleaning sections. Mist eliminators on the mill exhaust, fume extraction with scrubbing on the cleaning line, and hot air fans on the strip dryers.
The gas
Air saturated with moisture from drying, with condensation on any cool surface. Drainage, a shaft seal and a material that tolerates wet running are part of the specification.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. | Backward inclined and radial tipped |
| Mist Eliminator | Separates entrained liquid droplets from a vapour or gas stream, ahead of a compressor, a fan or a stack.. | Demister Knockdown Vessel |
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| Ventilation Fan | Moves air through a plant or building for fresh air supply, heat removal and fume dilution where the system is ducted. | Backward inclined and forward curved |
| HVAC | Supply, return and exhaust fans for heating, ventilation and air conditioning of plant and office space. | Axial, backward inclined and forward curved |
