Although the solution was initially functional, ANDRITZ wanted to develop it further to improve the everyday usability which is why the collaboration with the Nettingsdorf mill was so important.
“The co-development and piloting stage was an amazing time for us at the mill,” says Marchgraber. “To bring the ANDRITZ WLA experts together with the recovery boiler team was an excellent idea. These experts listened to all our needs and put into place almost all of the suggestions we had to enable the solution to give us all the information we needed.”
Lankila adds, “From the ANDRITZ point of view this was an excellent collaboration as we were approaching the development from two different angles; a company running a recovery boiler and a technology supplier. We took all Nettingsdorf’s requirements into consideration, then implemented them to the system.
“After many meetings, calls, and inputs from the mill team, accompanied by a multitude of fine tuning and trials, we ended up with a very successful result that suits both parties.”
A JOURNEY NOT JUST A DESTINATION
The result of the collaboration is the Metris WLA which uses standard instrumentation in the recovery boiler enhanced with modern machine learning tools to detect possible leaks. Operators have one all-inclusive display to check all relevant data connected with the boiler’s water and steam system which improves the capabilities to detect even the smallest leaks and will alarm operators in case a leak is suspected.
“This has been a journey and not just a destination,” concludes Marchgraber “The way the WLA system reported when first delivered to Nettingsdorf was completely transformed after this close collaboration between ANDRITZ experts and the mill operators. We now have a system that fully suits our needs, and one that gives us much more confidence when it comes to possible leaks.”
The new Metris WLA system from ANDRITZ is available for all new and existing recovery boilers.
