New recovery boiler and turbine
for Metsä Board’s Husum mill
A
new recovery boiler
and turbine has been
inaugurated at Metsä
Board’s mill at Husum
in Sweden.
At the ceremony in May
were, among others, project
partners and representatives
of Örnsköldsvik municipality.
Started up at the end of 2022,
the technology has increased
the mill’s bio-based energy
production that raises the mill’s
electricity self-sufficiency to more
than 80 per cent.
The new boiler and turbine are
part of a €380 million project, the
second phase of which will be the
replacement of the two current
fibre lines with one new line.
Chief executive of Metsä Board,
Mika Joukio commented: “The
renewal will strengthen the
Husum mill integrate’s role as an
efficient and sustainable platform
for the long-term development of
paperboard production and is an
important step towards our target
of entirely fossil-free mills.”
The renewal involved replacing

boiler is of a completely new
generation, we have trained
our staff extensively,” said
Olov Winblad von Walter, vice

mill.
The project also includes a
new control room and office,
which will gather the operation
and maintenance staff on the
same floor. “This will enable us
to establish new integrated ways
of working between technicians,
engineers, maintenance and
operators,” Winblad von Walter
added.
An investment programme is

World’s most productive
MG paper line for Gascogne Papier
Gascogne Papier in south west
France has ordered a PrimeLine
machine glazed (MG) paper
production line from Andritz for
its mill at Mimizan with start-up
planned for 2025.
The paper machine will have a
web width of 6.8 metres and a
design speed of 1,300 metres per
minute producing basis weights
from 25 to 120 gsm, using 100
per cent softwood unbleached

kraft pulp. The machine’s width
will make it the world’s widest
MG paper machine and with
a capacity of 125,000 tons per
year it will set a new industry
benchmark for uncoated MG
papers.
The core of the MG machine will
be the world’s largest PrimeDry
Steel Yankee. With a diameter of
26 feet (7.9m) the Yankee will, it
is said, enable energy-efficient
drying while providing excellent
surface properties such as gloss
and dimensional stability.
The Yankee will be
manufactured and transported
in sections and assembled at the
customer’s site.
The Andritz MG line will
replace three of the mill’s four
paper machines. The main target
of the investment is to establish
a multi-grade production line,
to increase the annual capacity
of folding boxboard by around
200,000 tonnes. The investment is
expected to be completed in the
fourth quarter of 2023.
The Husum mill is an integrated
board and pulp mill producing
folding boxboard, uncoated white
kraftliner and bleached chemical
pulp.
capable of producing more than
80 different grades of ribbed and
unribbed paper.
Dominique Coutière, chief
executive of Gascogne Papier,
explains: “Investments of that
scale are a big milestone for
companies in our business. The
selection of the right partner
is a decisive success criterion.
The experience and references
in the MG sector as well as the
customer-orientated approach
of Andritz convinced us. We are
really looking forward to a great
partnership.”
