Dedusting of a drum dryer during the processing of coal treatment

At our customer Enerco's location in the harbour of Amsterdam coal from all over the world is refined.

The coal is stored for a certain time and then processed. During the drying process in a drum dryer a high percentage of dust arises. The 22-year-old filter, which was used for the dedusting, was exchanged for a new, modern unit from us.

The extracted dust is explosive and combustible. For this reason the complete unit has been supplied in the EX-version as per to ATEX – Directive 94/9/EC. The filter itself is defined as an Ex-Zone 20. As an additional special feature therefore a flameproof rotary feeder and a spark guarded ventilator is fitted.

Technical data

In this case a Type SK36/4.5m VI R filter with bursting discs for pressure relief in the event of an explosion. The volume of air to be cleansed is 36.000 m³/h.
