Andritz to Supply Recovery Boiler to PCA's Valdosta, GA Mill

Nov. 6, 2009 - Andritz said that it 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 containerboard mill in Georgia (USA).

According to Andritz, 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 920 F (493 C), Andritz said.

The new unit will replace three existing boilers installed in the 1950's and 1970's, Andritz added.

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, Andritz said.

Start-up of the new boiler is scheduled for October 2011.
