LabTecta IAP solves ash dust problem

With Jonas Valdbjørn

What was the main problem at this site and what was the cause? Why was the cold air entering the system?

The seal was running dry and could not keep tight over time and then the cold humid air leaked into the furnace which caused ashes to crystallize around the shaft, damaging it, and it was blocking up the pipework further down the line.

The initial problem obviously led to multiple difficulties. Why was this and could it have been prevented?

Not with a normal working seal, the LabTecta non-contacting design is the right way to go.

How serious was the problem and how much worse could it have become if AESSEAL had not intervened? Why was it proving so costly?

The work on changing the axels every second year is a huge and expensive task. Also the issue was just repeating itself, and the blocked pipework significantly decreased the performance of the furnace.

Was the solution obvious and why?

The solution was quite obvious, hence the hot air purge would shield the furnace from the cold humid air.

Was it a difficult application to work on?

Not really. After measuring the axel and flange, the LabTecta designer quickly created the flange mount to swap the old single seal with this newly developed LabTecta^®IAP flange mounted.

Was the customer an existing AESSEAL client and how pleased were they with the results?

They have been a long-time customer and they are very pleased with the work we have carried out. This was one of the last troublemakers at the plant, and we have been helping them for years with pumps that were running faulty.
