We have recently installed a new design venturi orifice steam trap to a steam system at a customer with very good results. We have previously been in a discussion on this forum regarding these type of traps with some very negative comments about them.
Is there anyone else out there that has tried these types of steam traps? I would love to hear about your experiences. Our customer has seen some very good savings based on controlled measuring. The project included the replacement of all main steam traps as well as all process heat exchangers and cooking pots. The heat exchangers were running with a control valve modulating the steam flow and the cooking pots were manual open / close only.
It was decided that 6 months prior to and 6 months after the project, no other changes would be made to the steam system so that an accurate before and after comparison could be done. After the six months of measuring were completed after the traps were fitted the feedback was that a 18% boiler fuel saving was achieved, heat exchanger applications are performing very well with zero water hammer on the system and with an 8% improvement in reaching temperature on the process. The cooking pot applications are all reaching temperature satisfactorily with no noticeable improvement but also no worse than before.
We are going to be looking into this for further findings but are very encouraged by the results as we have been a bit sceptical regarding these traps.
As I mentioned before, feedback or other experiences would be greatly appreciated.
BEFORE AND AFTER
