Andritz will supply a Herb recovery boiler and a pre-evaporation plant


Customer: Smurfit Kappa Nettingsdorf

Production: Kraftliner

Supplier: Andritz 

Description: Andritz will supply a Herb recovery boiler and a pre-evaporation plant.

Details: The new investments are part of the company’s Future Energy Project, which involves the implemention of sustainable energy initiatives at the Nettingsdorf mill.

In addition to reducing emissions, the new Herb recovery boiler will produce more electricity than a traditional one. The boiler for Nettingsdorf will have several advanced features, including a smelt spout robot, an advanced sootblowing control with a hanging parts’ weight change indicator, and a process simulator. The EPC delivery scope covers mechanical equipment, automation, electrification, and instrumentation.

As a boost to energy efficiency at the mill, the new pre-evaporation plant utilizes Andritz’s proven Mechanical Vapor Recompression (MVR) technology to increase the Nettingsdorf mill’s evaporation capacity. MVR units operate with very low specific energy consumption and also produce clean condensate that will be reused in other mill processes to minimize consumption of fresh water.

Start-up: Start-up of the pre-evaporation plant and the new recovery boiler is scheduled for mid-2019 and mid-2020, respectively.
