ANDRITZ has received an order from Stora Enso to deliver a new debarking line, a new biomass boiler, and to upgrade the recausticizing plant for its Oulu mill in Finland.
The scope of supply, on EPC basis, includes:
- New debarking line, equipped with digital Smart Wood Processing products, with a capacity of about 270 m3 solid wood over-bark per hour, providing excellent debarking results with very low wood losses.
- New biomass power boiler with a steam production capacity of 216 t/h based on the high-efficiency ANDRITZ EcoFluid bubbling fluidized bed (BFB) technology, ensuring low NOx and other gaseous emissions.
- Recausticizing plant upgrade for 5,000 m3/d white liquor production. The delivery includes new generation LimeLine recausticizing equipment such as LimeWhite-H filter maximizing the white liquor quality and minimizing effluent amount, and StiroX white liquor oxidizer.
The order is part of Stora Ensoʼs project to convert a former paper machine at the Oulu mill into a high-volume consumer board production line.
This order demonstrates the ongoing solid business relationship between ANDRITZ and Stora Enso. ANDRITZ also supplied production technologies and key process equipment to the Oulu mill for the first machine conversion from paper to kraftliner in 2021, which included the rebuild of the fiberline and drying machine, as well as modernization of the stock preparation system.
