Based on the Andritz “upgrade on-the-fly” concept, the complete process control system for the existing boiler, which has been operated as standby boiler since 1993 and is equipped with an S5 control system, was replaced within a very short time.
Thanks to this concept and a comprehensive FAT (Factory Acceptance Test) together with the Hamburger Containerboard operating personnel, all four boilers in boiler house 3 were fired successfully five days before scheduled start-up, and high-quality steam was produced for the paper machine.
After upgrade of the entire PM3 and system upgrades of pulping lines 2, 3, and 4, as well as of the PM4 auxiliaries station by Andritz Automation, start-up of the boiler was an important milestone for Hamburger Containerboard in bringing the mill’s entire process control system up to a uniform, modern standard. Hamburger Containerboard produces 445,000 tons of corrugated base board from 100% waste paper in Pitten.
