“HOT” PROBLEMS

IN

SOOTBLOWERS


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

Time for a Change

4. Flue gas / oxygen leakage

through wall box opening

5. Lance stuck (leading to

bent lance) due to

combustion fines blocking

the opening

6. Steam leakage because of

malfunctioning gland

packing

7. Lance/feeder tube wear to

due to abrasive roller

General

“movement” problems

with sootblowers


• 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.


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




• 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.


THE SEELEN

DIFFERENCE


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


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


WHAT MAKES US SPECIAL

Less costs in the long run

Protection of the environment

Soot blower systems

(after modification)


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.


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
