BAT is to reduce HCl and HF emissions from the melting furnace by using one or a combination of the following techniques:
| A description of the techniques is given in Section 1.10.4. | |
| Techniquef1 | Applicability |
|---|---|
| (i) Selection of raw materials for the batch formulation with a low content of chlorine and fluorine | The applicability may be limited by the constraints of the type of glass produced at the installation and the availability of raw materials |
| (ii) Dry or semi-dry scrubbing, in combination with a filtration system | The technique is generally applicable |
Table 18
BAT-AELs for HCl and HF emissions from the melting furnace in the flat glass sector
| The conversion factor reported in Table 2 (2,5 × 10–3) has been applied. | ||
| The higher levels of the range are associated with the recycling of filter dust in the batch formulation | ||
