ANDRITZ Inc., a member of international technology Group ANDRITZ, has been selected by Domtar Corporation to provide equipment and technical services for conversion of a power boiler and a recovery boiler at their Kingsport paper mill, in Kingsport, TN, USA. This mill will be converted into Domtar’s first packaging facility.

As part of this state-of-the-art conversion, the Kingsport Mill needed to repurpose their steam generation equipment. ANDRITZ will convert an existing recovery boiler into a natural gas-fired power boiler with back-up fuel oil capability by supplying the main equipment, including low NOx burners and associated fuel and air systems. ANDRITZ will also provide equipment for the mill to modify an existing bubbling fluidized bed (BFB) power boiler so that it can accommodate a change in fuels from wood and sludge firing to corrugated cardboard (OCC) rejects, natural gas, and fuel oil firing.

The scope of supply also includes boiler cleaning devices, pressure part upgrades, material handling equipment, air/flue gas system upgrades, and environmental equipment to enable the mill to meet the highest environmental standards.

ANDRITZ’s extensive experience with multi-fuel boilers and air pollution control were decisive reasons for Domtar to award the order to ANDRITZ.

Once completed, Domtar’s Kingsport Mill will become North America’s premier lightweight containerboard facility – able to produce over 600,000 tons of high-quality recycled linerboard and corrugated medium annually. This level of capacity will make the Kingsport machine the second largest in North America for recycled containerboard.
