Andritz has received an order from BillerudKorsnäs to supply a HERB recovery boiler for its mill in Frövi, Sweden. Start-up is scheduled for the end of 2023. The new boiler will replace the existing recovery boiler that has been in operation in Frövi since 1969.
The Andritz scope of supply includes a HERB recovery boiler designed for the current pulp production level, but also to support a future black liquor combustion capacity of 1,670 tds/d and with future steam parameters of 100 bar and 505°C to maximize power generation.
Andritz will also supply a high-density concentrator solution to increase the black liquor concentration. This will improve operation and increase power generation by the HERB recovery boiler at Frövi mill even further.
