Swedish forest industry group Södra has entrusted international technology group ANDRITZ with the upgrade of three electrostatic precipitators (ESPs) for the recovery boiler at the Mörrum pulp mill. The mechanical and electrical refurbishments will extend the ESPs’ lifetime and enable an increase of the boiler’s capacity while ensuring compliance with the current emission standards. ANDRITZ will replace the discharge electrodes and collecting plates in the ESPs’ first fields and install state-of-the-art high voltage energization units – Switched Integrated Rectifiers (SIR) – in all fields. These latest-generation SIRs, equipped with silicon carbide power electronics, offer the highest electrical efficiency in the market, resulting in considerable energy savings for plant operators. ANDRITZ’s multipeak electrodes will enhance the recovery of residual salts to be recirculated into the process. This upgrade will be carried out on one ESP at a time and does not require costly and time-consuming field extensions. As a result, downtime of the recovery boiler and impact on the mill’s production will be reduced to a minimum. ANDRITZ has supplied ESP solutions to hundreds of mills worldwide, including two other Södra pulp mills in Sweden. The local support from the dedicated ANDRITZ team in Växjö, combined with the group’s global expertise, ensures a smooth project execution. - End - ANDRITZ GROUP 3 D model of ANDRITZ SIR installation
