  "text": "BAT is to reduce HCl and HF emissions from the melting furnace by using one or a combination of the following techniques:\nA description of the techniques is given in Section 1.10.4.\nTechnique\nApplicability\n(i)\nSelection of raw materials for the batch formulation with a low content of chlorine and fluorine\nThe applicability may be limited by the constraints of the batch formulation for the type of glass produced at the installation and the availability of raw materials\n(ii)\nMinimisation of the fluorine and/or chlorine compounds in the batch formulation and optimisation of the fluorine and/or chlorine mass balance\nFluorine compounds are used to confer particular characteristics to special glasses (i.e. opaque lighting glass, optical glass).\nChlorine compounds may be used as fining agents for borosilicate glass production\nThe technique is generally applicable within the constraints of the quality requirements for the final product.\n(iii)\nDry or semi-dry scrubbing, in combination with a filtration system\nThe technique is generally applicable\nTable 42\nBAT-AELs for HCl and HF emissions from the melting furnace in the special glass sector\nThe conversion factor of 2,5 × 10–3 (see Table 2) has been used; with some values being approximated. A case-by-case conversion factor may have to be applied based on the type of production.\nThe higher levels are associated with the use of materials containing chlorine in the batch formulation.\nThe upper value of the range has been derived from specific reported data.\nParameter\nBAT-AEL\nmg/Nm3\nkg/tonne melted glass\nHydrogen chloride, expressed as HCl\n< 10 – 20\n< 0,03 – 0,05\nHydrogen fluoride, expressed as HF\n< 1 – 5\n< 0,003 – 0,04",
