Division BAT 26
United Kingdom
In order to prevent or reduce diffuse emissions from charging, smelting and tapping operations in primary and secondary copper smelters and from holding and melting furnaces, BAT is to use a combination of the techniques given below.
| Description of the technique is given in Section 1.10. | ||
| Technique | Applicability | |
|---|---|---|
| a | Briquetting and pelletisation of raw materials | Applicable only when the process and the furnace can use pelletised raw materials |
| b | Enclosed charging system such as single jet burner, door sealingf1, closed conveyers or feeders equipped with an air extraction system in combination with a dust and gas abatement system | The jet burner is applicable only for flash furnaces |
| c | Operate the furnace and gas route under negative pressure and at a sufficient gas extraction rate to prevent pressurisation | Generally applicable |
| d | Capture hood/enclosures at charging and tapping points in combination with an off-gas abatement system (e.g. housing/tunnel for ladle operation during tapping, and which is closed with a movable door/barrier equipped with a ventilation and abatement system) | Generally applicable |
| e | Encapsulate the furnace in vented housing | Generally applicable |
| f | Maintain furnace sealing | Generally applicable |
| g | Hold the temperature in the furnace at the lowest required level | Generally applicable |
| h | Boosted suction systems | Generally applicable |
| i | Enclosed building in combination with other techniques to collect the diffuse emissions | Generally applicable |
| j | Double bell charging system for shaft/blast furnaces | Generally applicable |
| k | Select and feed the raw materials according to the type of furnace and abatement techniques used | Generally applicable |
| l | Use of lids on throats of rotary anode furnace | Generally applicable |
