Andritz to Supply Biomass Boiler to Graphic Packaging's Macon Mill

Andritz BFB power boiler.

Feb. 3, 2011 - Andritz said that it has been awarded an order by Graphic Packaging International to supply a 350,000 lb/h (160 t/h) steam boiler using woody biomass and primary clarifier sludge as fuels for the company's paperboard mill in Macon, Georgia, USA. Start-up of the boiler is scheduled for summer 2013.

The value of the order was not disclosed.

The scope of the order includes a Bubbling Fluidized Bed (BFB) steam boiler, fuel and bottom ash handling systems, and the boiler safety system.

It is projected that the biomass boiler will effectively reduce greenhouse gas emissions by approximately 200,000 ton/a (180,000 metric ton/a), Andritz said.

The new biomass boiler is expected to make the Macon mill energy self-sufficient (electrical power and steam generation), which will reduce Graphic Packaging's energy costs and dependency on fossil-fuel based alternatives. The mill expects to become a net producer of electricity, Andritz added.

Start-up of the boiler is scheduled for summer 2013.

The Macon mill currently produces about 1,600 tons of paperboard per day.
