Division BAT 27
United Kingdom
In order to reduce diffuse emissions from Peirce-Smith converter (PS) furnace in primary and 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 | |
|---|---|
| a | Operate the furnace and gas route under negative pressure and at a sufficient gas extraction rate to prevent pressurisation |
| b | Oxygen enrichment |
| c | Primary hood over the converter opening to collect and transfer the primary emissions to an abatement system |
| d | Addition of materials (e.g. scrap and flux) through the hood |
| e | System of secondary hoods in addition to the main one to capture emissions during charging and tapping operations |
| f | Furnace located in enclosed building |
| g | Apply motor-driven secondary hoods, to move them according to the process stage, to increase the efficiency of the collection of secondary emissions |
| h | Boosted suction systemsf1 and automatic control to prevent blowing when the converter is ‘rolled out’ or ‘rolled in’ |
