  "text": "BAT is to reduce NOX emissions from the melting furnace by using one or a combination of the following techniques:\nA description of the techniques is given in Section 1.10.2.\nTechnique\nApplicability\n(i) Combustion modifications\n(a)\nReduction of air/fuel ratio\nApplicable to air/fuel conventional furnaces.\nFull benefits are achieved at normal or complete furnace rebuild, when combined with optimum furnace design and geometry\n(b)\nReduced combustion air temperature\nApplicable to air/fuel conventional furnaces within the constraints of the furnace energy efficiency and higher fuel demand. Most furnaces are already of the recuperative type.\n(c)\nStaged combustion:\n(d) Air staging\n(e) Fuel staging\nFuel staging is applicable to most air/fuel, oxy-fuel furnaces.\nAir staging has very limited applicability due to its technical complexity\n(d)\nFlue-gas recirculation\nThe applicability of this technique is limited to the use of special burners with automatic recirculation of the waste gas\n(e)\nLow-NOX burners\nThe technique is generally applicable.\nFull benefits are achieved at normal or complete furnace rebuild, when combined with optimum furnace design and geometry\n(f)\nFuel choice\nThe applicability is limited by the constraints associated with the availability of different types of fuel, which may be impacted by the energy policy of the Member State\n(ii)\nOxy-fuel melting\nThe maximum environmental benefits are achieved for applications at the time of a complete furnace rebuild\nTable 23\nBAT-AELs for NOX emissions from the melting furnace in the continuous filament glass fibre sector\nThe conversion factor reported in Table 2 (4,5 × 10–3) has been applied.\nThe achievable levels depend on the quality of the natural gas and oxygen available (nitrogen content).\nParameter\nBAT\nBAT-AEL\nmg/Nm3\nkg/tonne melted glass\nNOX expressed as NO2\nCombustion modifications\n< 600 – 1 000\n< 2,7 – 4,5\nOxy-fuel melting\nNot applicable\n< 0,5 – 1,5",
