Energy savings through efficient operation
High
energy
savings
through
conversion:
Due to the installation of a dreizler
®
gas burner
marathon
®
M 2001 ARZ to
an existing steam boiler Hartley &
Sugden (1,7 MW) the energy costs have
been reduced significantly in the factory
of the Kookaburra Ltd. in Durham,
Great Britain.
Moreover, the
marathon
®
gas burner
was equipped with the dreizler
®
speed
control
frequency
: The variable speed
of the fan is adapted to the burner
capacity and ensure additionally an
effective energy savings of the burner.
Tony Gilroy, Managing Director
Kookaburra Ltd.: „Our cost of natural gas
in relation to usage on our steam boiler
has significantly reduced……to touch and
feel these savings week on week is
nothing short of a great success story.”
Example of an installation
Successful conversion plant in the paper industry
In its own steam power plant of the
paper mill Palm GmbH & Co. KG a water
tube boiler was adapted from oil
heating to LOW-NOx gas combustion by
2 x dreizler
®
marathon
®
M 10003.3
ARZ.
NO
x
emissions of < 100 mg/kWh
according to EN 676 should be achieved
and thus well below the requirements of
the 13. BImSchV.
Within a short conversion time the both
modern gas burners
marathon
®
M 10003.3 ARZ in DUObloc construction
were installed to a water tube boiler
of Deutsche Babcock & Wilcox.
Even in the very short combustion
chamber of 3,5 m of the water tube
boiler, the desired NO
x
emissions
were clearly below <100 mg/kWh.
These values are well below the
regulatory values according to the
13. BImSchV (Medium temperature
>210°C
≤ 0,15 g/m3 at 3% O
2
).
We thank the team of Papierfabrik
Palm
for
the
successful
implementation of this joint project.
