When lead compounds are used for the manufacturing of lead crystal glass, BAT is to reduce lead emissions from the melting furnace by using one or a combination of the following techniques:
| A description of the technique is given in Sections 1.10.1 and 1.10.5. | |
| Techniquef1 | Applicability |
|---|---|
| (i) Electric melting | Not applicable for large volume glass productions (> 300 tonnes/day). Not applicable for productions requiring large pull variations. The implementation requires a complete furnace rebuild |
| (ii) Bag filter | The technique is generally applicable |
| (iii) Electrostatic precipitator | |
| (iv) Dry or semi-dry scrubbing, in combination with a filtration system | |

BAT-AELs for lead emissions from the melting furnace in the domestic glass sector when lead compounds are used for manufacturing lead crystal glass
| The values refer to the sum of lead present in the flue-gases in both solid and gaseous phases. | ||
| A conversion factor of 3 × 10–3 has been applied (see Table 2). However, a case-by-case conversion factor may have to be applied for specific productions. | ||
