Valmet automation for Blue paper’s SRF boiler
Finland’s Valmet will supply a DNA control system for the new Solid Recovered Fuels (SRF) boiler Blue Paper SAS is building at its site in Strasbourg, France. Start-up is planned for spring 2018.
The mill already uses a DNA system to control most of its energy and papermaking processes and it will be an advantage for operators and maintenance technicians to keep the same DCS environment for the new SRF plant.
The 800 I/O DNA system will control the boiler, fuel storage, and supply and utilities, with integration with the current Valmet automation system and communication with external systems such as analyzers and the unloading system.
The Valmet DNA is part of Blue Paper’s €24-million project to install a 22-MW steam production plant using SRF to replace the mill’s two gas boilers, with output of 30 tonnes/h of steam. The project is part of Blue Paper’s strategy to reduce the carbon footprint of its operations and products by reducing gas consumption by 80% and producing 40% of the steam needed by its operations. Blue Paper will use local and mill waste as fuel.
Valmet says its DNA is a highly integrated automation system for power plant control and monitoring. In addition to offering a modern DCS system, it has integrated turbine control and protection, machine condition monitoring and protection, electrical power distribution and performance monitoring and reporting.
Blue Paper’s Strasbourg mill produces corrugated case material made solely from 100% recovered paper. Blue Paper SAS was established in 2013 after UPM Kymmene group, the mill’s previous owner, sold it to the Klingele Group (Germany) and the VPK Packaging Group (Belgium), who converted the magazine paper mill into one of Europe’s biggest corrugating base paper mills with a capacity of over 400 kt/y.
