Tembec has contracted Andritz to supply a SulfitePower boiler plant for its Témiscaming specialty pulp mill in Quebec. The new boiler is part of $190-million upgrade at the plant.
Start-up of the boiler is scheduled for the final quarter of 2013. It will burn waste sulfite liquor, a co-product of the specialty cellulose manufacturing process, and will replace three older boilers.
For this order, Andritz Energy & Environment will provide the boiler pressure part and steel structures, liquor and gas burners, fan, air preheater, air and flue gas ducts, and the soot blower.
In the power boiler plant, 78.5 t of liquor will be burned and 222 t of high-pressure steam produced per hour. A new steam turbine with an output of 50 MW will generate green electricity that will be supplied to the provincial grid. Ammonium bisulfite will be recovered in a subsequent flue gas cleaning plant.
Start-up of the turbine is scheduled for May 2014.
