1. Corrosion of lance tubes
due to flue gas ingress in
the lance and inner
tubes
2. Erosion/Corrosion of
boiler tubes due to wet
steam and condensate
3. Blow-out of gland
packing due to wet
steam and condensate
Proper sealing. Air supply
should be 30-50mm
WC(2,91- 4,85
mbar)higher than the
highest flue gas pressure
Regular control on the
limit switches of the
blowing lances
Proper replacement of the
essential parts, if
damaged, during TA

General
“movement” problems
with sootblowers
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
• The translational
forces resulting
from the travel path
of the soot blower
• The rotational
forces resulting
from the transport
of the steam ,
through the nozzle,
in the boiler.
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
Movement problems with Sootblowers
• Soot Blowers(except
axial sootblowers and
rake blowers)perform
translational
and rotational
movements.
• These movements
lead to the formation
of helical notches
• The old roller bracket
leads to a strong
gouging of the lance
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
Movement problems with Sootblowers
Movement problems with Sootblowers
• The retraction, push
forward and running
the lance is very
difficult with the old
roller bracket.
• The gear motor has
a lot of power to
expend the lance
forward and
backward move.
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
The Seelen difference
• The seelen roller bracket
leads to distribution of
the translational and
rotational forces
• The consequence of
this distribution
no wear of the lance,
no abrasion
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
Our success is based on the
patents for two inventions: the
brush sealing and the rotating
blower lance
Applying these unique Seelen
technologies helps achieve cost
savings and a more efficient
operation of the plant
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
WHAT MAKES US SPECIAL
Less costs in the long run
Protection of the environment
Soot blower systems
(after modification)
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
BEFORE & AFTER COMPARISON
The standard lamellar seal
and the non-rotating lance
show typical wear at the
lance surface.
Using the Seelen sealbrush
and the rotating lance
support, there is absolutely
no wear at the lance surface.
Engineering Office J. Seelen GmbH I [email protected] I www.seelen.de
ADVANTAGES OF A SEELEN SYSTEM
Improvement of system availability and manoeuvrability
Increase efficiency (lower fuel consumption)
Extend life of the steam generator / furnace
Increase operating cycle / run length
Reduce maintenance costs
Increased safety and avoid equipment damage
Easy handling of assembling and installing the blower
