BAT-associated emission levels for metals from the flue-gases of kiln firing processes
| Low levels have been reported based on the quality of the raw materials and the fuels. | ||
| Low levels have been reported based on the quality of the raw materials and the fuels. Values higher than 0,03 mg/Nm3 have to be further investigated. Values close to 0,05 mg/Nm3 require consideration of additional techniques (e.g. lowering of the flue-gas temperature, activated carbon). | ||
| Metals | Unit | BAT-AEL(average over the sampling period (spot measurements, for at least half an hour)) |
|---|---|---|
| Hg | mg/Nm3 | < 0,05f1 |
| Σ (Cd, Tl) | mg/Nm3 | < 0,05f2 |
| Σ (As, Sb, Pb, Cr, Co, Cu, Mn, Ni, V) | mg/Nm3 | < 0,5 |
