recovery boiler took over from the
old one and was running at nominal
capacity after just one day. “This
project was carried out on another
level, especially when it came to
safety,” said Leitgeb. “And the
start-up was brilliant. The Project
Manager and team from ANDRITZ
were completely focused and always
pushing to make sure all requirements
were met and the timeline was
followed.
“We stopped the mill for one
day and the next day we had full
production. There was such a fast
ramp-up after the start-up; I could
even say the recovery boiler was
outperforming. We did all this during
normal operation; it really was a case
of out with the old and in with the
new and up and running again – in just
one day,” he exclaimed.
“We were very pleased; the
commissioning went well and
the start-up and ramp-up to full
production went exceedingly well,”
added Wikstedt.
Leitgeb commented that now all
capacity numbers agreed on with
ANDRITZ have been fulfilled, he
said, “The expectations were really
high with this project and the senior
management at Smurfit Kappa
have followed progress very closely.
The recovery boiler is now running
smoothly 99% of the time with the
major difference being that it’s not a
bottleneck anymore.
“With emissions, we are

outperforming, the energy efficiency is
brilliant and the chemical recovery is
much better than before. All in all our
expectations have been met, despite
the challenges.”
The latest technology
for recovery boilers
Nettingsdorf is no stranger to
the implementation of the latest
technology. The mill has already
some of the newest technology from
ANDRITZ on its fibreline in operation,
including a number of the world’s first
installations.
The new recovery boiler delivered
to Nettingsdorf comes complete
with some of the latest advanced
autonomous technology developed
by ANDRITZ, including a Smelt Spout
Robot, soot blowing control with a
Metris HEWI Weight Indication, a
Metris Water Leakage Advisor (WLA)
system and a process simulator.
Michael Strach, Pulp Mill Manager,
Smurfit Kappa Nettingsdorf, said of
the Smelt Spout Robot installed on
the smelt deck of the recovery boiler,
“This is a very important step for us at
the mill in terms of safety as the smelt
deck is one of the most dangerous
places to work in at the mill.
“We have been really surprised at
how eHective the robot is; we were
expecting teething troubles, but apart
from a maintenance learning curve it

has been very eHective right from the
beginning. It has now made the smelt
deck a lot safer for our mill personnel.”
Strach also commented on the
process simulator that was supplied
alongside the new recovery boiler,
“The simulator is perfect for us as
we can train our personnel how to
run and operate the boiler. We can
simulate different scenarios, including
dealing with tricky situations, learning
what to do and, importantly, what
not to do when these occur. We use
the simulator a lot to see how the
boiler reacts to various events; it’s very
useful for gaining experience of boiler
operation.”
The Metris WLA system is the
first of its kind supplied to a pulp
mill, as it comes with the new
feature of machine learning. The
system was developed in close cooperation between ANDRITZ and the
Nettingsdorf Mill. Walter Marchgraber,
Pulp Mill Manager, Smurfit Kappa
Nettingsdorf said, “The Metris WLA
came as a result of close collaboration
between Nettingsdorf recovery boiler
management and ANDRITZ. Safety is
of utmost importance to us at the mill,
so to have a system that warns us of
possible water leakage is a great tool
to have for our operators.
“The new system will alert
operators to a possible leak, enabling
them to take action and therefore
prevent the chance of an explosion in
the recovery boiler.”
