Lenzing AG plans to upgrade the 1K6 gas boiler at its Lenzing production site in Austria by replacing an obsolete third-party control system with a complete distributed control system (DCS) for monitoring and control, plus a historian solution for information management, with safety-related systems based on HIMA technology, the supplier Valmet announced.
The upgrade is intended to standardize the control room on one DCS platform at this part of the facility and to extend lifecycle support while applying cybersecurity and reliability requirements to a critical boiler operation. The new control system will connect with the site’s existing distributed control system.
Lenzing is scheduled to take over the delivery during the first quarter of 2027.
The Lenzing site produces dissolving wood pulp and regenerated cellulose fibers. The site has used successive generations of distributed control systems since the 1990s across the pulp mill and boiler areas, and its installed automation base includes four turbines that are fully automated.
The DCS platform described for the boiler is fully web-based and designed for critical power generation use, with high availability and cybersecurity functions and integrated process control, monitoring, and analytics for continuous operation. The historian component will store and manage operational information from the boiler area for use in reporting and analysis.
