Sumitomo SHI FW awarded CFB boiler modernisation contract in Austria

Sumitomo SHI FW (SFW) has been awarded a contract by Sappi Europe to modernise an existing circulating fluidised bed (CFB) boiler at a paper mill.

The updated boiler will result in a 30% reduction in carbon dioxide emissions at the Gratkorn Pulp and Paper mill in Austria.

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

The modernisation will allow the pulp and paper plant to completely shift from coal to multiple sustainable and renewable fuels. The new emissions control system includes bag filters and selective non-catalytic reduction (SNCR), which will ensure the facility meets the newest best available technologies standards, particularly regarding dust and nitrogen oxides emissions.

Kari Kohvakka, SVP service at SFW, said: “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 decarbonisation commitments, while reaping the benefits of reliable energy supply and extending the lifetime of their current assets.”

The project will be completed at the end of 2021.
