BAT for hot blast stoves is to reduce emissions by using desulphurised and dedusted surplus coke oven gas, dedusted blast furnace gas, dedusted basic oxygen furnace gas and natural gas, individually or in combination.

The BAT-associated emission levels, determined as daily mean values related to an oxygen content of 3 %, are:

• sulphur oxides (SO_x) expressed as sulphur dioxide (SO₂) < 200 mg/Nm³

• dust < 10 mg/Nm³

• nitrogen oxides (NO_x), expressed as nitrogen dioxide (NO₂) < 100 mg/Nm³.
