Division BAT 30
United Kingdom
In order to reduce diffuse emissions from a top-blown rotary converter (TBRC) furnace in secondary copper production, BAT is to use a combination of the techniques given below.
| Description of the technique is given in Section 1.10. | ||
| Technique | Applicability | |
|---|---|---|
| a | Operate the furnace and gas route under negative pressure and at a sufficient gas extraction rate to prevent pressurisation | Generally applicable |
| b | Oxygen enrichment | Generally applicable |
| c | Furnace located in enclosed building in combination with techniques to collect and transfer diffuse emissions from charging and tapping to an abatement system | Generally applicable |
| d | Primary hood over the converter opening to collect and transfer the primary emissions to an abatement system | Generally applicable |
| e | Hoods or crane integrated hood to collect and transfer the emissions from charging and tapping operations to an abatement system | For existing plants, a crane integrated hood is only applicable to major upgrades of the furnace hall |
| f | Addition of materials (e.g. scrap and flux) through the hood | Generally applicable |
| g | Boosted suction systemf1 | Generally applicable |
