The process
The sinter strand draws air down through the burning bed with a large ID fan, the main exhauster, handling waste gas that is hot, dusty and acidic. Dedusting fans serve the cooler and the material handling, all on abrasive ore and flux fines.
The gas
Sinter strand waste gas carries ore and flux fines with acid components from the sulphur in the fuel. Wear and corrosion both act on the wheel; material and liner selection follow the gas analysis.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| 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 |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| Combustion Air Blower | Feeds a burner with air at the pressure the burner register needs. | Backward curved and radial tipped |
| Fan Silencer | An absorptive silencer at the fan inlet, outlet or in the duct, cutting fan noise with minimum pressure loss.. | Silencer |
