Expanded Metal Screens as Flow Controllers

Abstract [en]

The purpose of this project was to investigate if expanded metal screens can deflect the flow around a bend, into the reactor of a selective catalytic reduction unit and to find a way of determining which screen would be optimal.

The current solution is very heavy compared to expanded metal. Construction costs may be reduced if the expanded metal screens work.

A screen is needed to minimize the wear on the catalysts in the reactor.

For this project a model , in scale 1/10, measuring equipment, consisting of Prandtl-tubes, an anemometer and smoke torches were used. Eight different expanded metal screens were tested.

The results showed that the expanded metal works well for the purposes of deflecting flow. The angle of the flow entering the catalysts was good, and the flow was evenly distributed across the cross-section of the reactor.
