Supersonic nozzles versus venturi

Posted in: , on 14. Dec. 2016 - 15:46

Dears,

The famous way for pulse jet cleaning system of bagfilters is the application of venturi inside the bag (or sometimes outside).

However I have read an article that supersonic nozzles which eliminate venturi, is better system. In supersonic nozzles, there is only small pipe welded to plow pipe and there is n't anything else.

Is there any person here who has experienced supersonic nozzles?
