Andritz to modernize swedish boilers
Andritz recently announced it has received orders from Stora Enso Nymölla and Domsjö Fabriker, to modernize a recovery boiler and a sulfite liquor boiler. The modernizations supplied by Andritz Energy & Environment will raise the capacity of the two boiler plants by up to 20%. Both start-ups are scheduled for 2013.
This technical concept is designed to extend the life of the boiler and lower the maintenance requirements. In addition to the capacity increase, scheduled shutdowns can be reduced to a minimum.
The scope of supply for the modernization of Domsjö Fabriker's sulfite liquor boiler number 9, which went into operation in 1962, includes replacement of the superheater and evaporator heating surfaces, as well as partial replacement of the front and rear walls of the boiler. A new design will improve the fouling behavior of the boiler and enhance efficiency by up to 20%. A very short installation period of 18 days is planned, ensuring the mill a very brief production stoppage, according to Andritz.
