Andritz has received an order from Packaging Corporation of America (PCA) to deliver a high energy recovery boiler (HERB), including a chloride and potassium removal system, to PCA’s Valdosta mill in Georgia. Start-up of the new recovery boiler is scheduled for October 2011.

The energy-efficient HERB technology allows a modern mill to produce more steam, and therefore more electrical energy, to support mill operations. For the Valdosta mill, the boiler is designed to operate at 1,500 psig (103 bar) pressure and a temperature of 920F (493C). The new unit will replace three existing boilers installed in the 1950s and 1970s.

Upon completion of the project, the Valdosta mill will use only internally generated wood waste and black liquor in its boilers, which will allow it to self-generate 100% of its electricity requirements. The new recovery boiler technology will also significantly reduce the mill’s air emissions compared to the older installed units.
