Division 43

BAT for storage and handling of pulverised coal is to prevent or reduce diffuse dust emissions by using one or a combination of the following techniques:

1. I..

   storing pulverised materials in bunkers and warehouses

2. II..

   using closed or enclosed conveyors

3. III..

   minimising the drop heights depending on the plant size and construction

4. IV..

   reducing emissions from charging of the coal tower and the charging car

5. V..

   using efficient extraction and subsequent dedusting.

When using BAT V, the BAT-associated emission level for dust is < 10 – 20 mg/Nm³, as the average over the sampling period (discontinuous measurement, spot samples for at least half an hour).
