Aker Kvaerner has been awarded a contract for the supply of a recovery boiler, to modernise the chemical recovery plant at UPM’s Kymi pulp mill in Kuusankoski, south eastern Finland. The contract value to Aker Kvaerner is approximately EUR 80 million. UPM is one of the world’s leading producers of printing papers and the clear market leader in magazine papers.
The recovery boiler will be part of the mill’s new recovery line, which will replace two existing lines that date back to the 1960’s and 1970’s. The new recovery plant will improve the pulp mill’s energy efficiency and decrease fossil carbon-dioxide emissions. The new generation recovery boiler will be designed for maximum power generation and it will increase the electricity production produced from biofuels.
Kvaerner Power, part of the Aker Kvaerner group, will supply the recovery boiler rated at 3600 tons of dry solids per day and steam parameters of 505°C and 103 bar. The delivery also consists of an odorous gas treatment system, a flue gas scrubber for effective heat recovery, and an ash leaching system for chloride and potassium reduction. The new recovery boiler will be ready for operation in the summer of 2008.
