The process
Hazardous, medical and municipal waste incinerators hold the furnace under draft with an ID fan that sits after the quench, scrubber, bag filter and carbon injection. The gas at the fan is wet and acidic. Combustion air and secondary air blowers serve the primary and secondary chambers.
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
| Carbon | Granular activated carbon bed sized for the solvent load and the required outlet |
| Fan | Spark resistant, on the clean side of the bed |
