Sumitomo SHI FW awarded CFB boiler upgrade project in Austria

Sumitomo SHI FW (SFW), a subsidiary of Japan-headed Sumitomo Heavy Industries Ltd (SHI) has announced that it has been awarded a contract by pulp and paper major Sappi Europe to modernize an existing circulating fluidized bed (CFB) boiler, which will result in a 30 percent carbon dioxide (CO2) emissions reduction at the Sappi Gratkorn Pulp and Paper mill in Austria.

In September 2020, Sappi Europe announced that it will invest in a complete modernization of boiler 11 at the Sappi Europe Gratkorn production site. This investment into state-of-the-art technology will see a shift from a coal boiler to a multi-fuel boiler in two phases with the goal to finally use only sustainable and renewable fuels.

According to a statement, SFW will design, supply, and erect the project, which includes modifications to the lower furnace, new heat shift system, biomass feeding system, bottom ash extraction system, and emissions control system, as well as dismantling and commissioning.

The modernization will allow the plant to completely shift from coal to multiple sustainable and renewable fuels. The new emissions control system include bag filters and selective non-catalytic reduction (SNCR), which will ensure the plant meets the newest Best Available Technologies (BAT) standards, especially regarding dust and nitrogen oxides (NOx) emissions.

SFW’s mission is to help our customers achieve their climate targets efficiently and cost-effectively. With this project, Sappi will be one step closer to achieving their decarbonization commitments, while reaping the benefits of reliable energy supply and extending the lifetime of their current assets, said Kari Kohvakka, SVP Service at SFW.

The project, the value of which has not been disclosed, will be completed at the end of 2021.
