Swedish mill chooses biomass boiler to dry pulp
By Cindy Macdonald
Rottneros Mill is planning to invest SEK 98 million (about $15.4 million) in a new biomass boiler. It will replace fossil oil as the energy source used to dry pulp in the mill’s flash dryers.
The company says this investment will also lead to the rebuilding of large parts of the mill’s energy system, which will increase energy efficiency significantly. The detailed planning work has begun and the new biofuel boiler will be completed and put into use around mid-2017.
“When we’re now investing in a new biofuel boiler, we will also optimize and rebuild our energy system at the mill. It will result in significant energy efficiency improvements and environmental benefits in terms of lower emission levels. The extents of the savings are at least SEK 25 million per year,” says Olle Dahlin, CEO of Rottneros Mill.
Rottneros Mill produces two different kinds of high yield pulp for paper producers, CTMP and groundwood pulp, and has for many years used oil to dry the pulp. When the new biomass boiler is completed, the mill’s energy consumption will entirely free of fossil fuels. The new biomass boiler has an effect around 18 MW and will replace an older biomass boiler. The supplier of the new boiler has not yet been selected.
