BAT is to reduce dust emissions from the waste gases of the melting furnace by applying an electrostatic precipitator or a bag filter system

A description of the techniques is given in Section 1.10.1.
Technique^f1	Applicability
Filtration system: electrostatic precipitator or bag filter	The technique is generally applicable. Electrostatic precipitators are not applicable to cupola furnaces for stone wool production, due to the risk of explosion from the ignition of carbon monoxide produced within the furnace

A description of the techniques is given in Section 1.10.1.

Technique^f1

Applicability

Filtration system: electrostatic precipitator or bag filter

The technique is generally applicable.

Electrostatic precipitators are not applicable to cupola furnaces for stone wool production, due to the risk of explosion from the ignition of carbon monoxide produced within the furnace

Table 46

BAT-AELs for dust emissions from the melting furnace in the mineral wool sector

Parameter	BAT-AEL
The conversion factors of 2 × 10^–3 and 2,5 × 10^–3 have been used for the determination of the lower and upper value of the BAT-AELs range (see Table 2), in order to cover both the production of glass wool and stone wool.
Parameter	mg/Nm³	kg/tonne melted glass^f2
Dust	< 10 – 20	< 0,02 – 0,050
