The process
Small two-chamber incinerators for hospital waste use a venturi or packed bed scrubber and an ID fan in stainless steel or FRP. Volumes are small and the duty is intermittent, so the fan is built for corrosion rather than for size.
The gas
Flue gas after the quench and scrubber is wet, acidic and still carries fine dust. The fan is in stainless steel or lined construction, with a shaft seal and drains, sized at the saturated density.
Selection for this process
| Type | Venturi for fine dust |
| Material | Stainless steel |
| Outlet | Mist eliminator ahead of the fan; fan in the same material as the scrubber |
