The recovery boiler was built in 1977 and its current capacity is roughly 2,000 metric tpd of dry solids. The upper and lower drum of the recovery boiler and the steam generating bank between them will be replaced by a new drum and separate boiler bank elements needed for heat recovery.
"The conversion will significantly extend the boiler’s lifetime, improve the boiler’s availability, secure safe operation, and reduce maintenance costs. Further advantages offered by a single-drum conversion compared with replacing the existing design with a similar one are a shorter downtime and the reliability of the solution," says Olli Ypyä, sales manager, Boiler Conversions, Metso.
Veitsiluoto Mill is situated in Kemi, Finland, and is part of Stora Enso’s Printing and Reading business area. The annual capacity of the integrated mill, with four paper machines and a pulp mill, groundwood mill, sawmill, and sheeting plant, totals a million metric tons of office paper and coated magazine paper, as well as 160,000 cubic meters of sawn timber. The pulp mill’s annual capacity of 375,000 metric tons is used as raw material for office papers. Veitsiluoto Mill has a workforce of roughly 1,000, around 750 who work for Stora Enso.
