PAPERTECH 2010
for a most successful event and wish
d l d dIndian Pulp and Paper Industry
participants today and all stake holders
continuous success and prosperity

3. With 600 paper mills in operation, a 7.8% projected annual
growth, and an estimated nationwide paper demand of 10.5
million tonnes in year 2010, the Pulp and Paper Industry plays
an important role in the Indian economy and the next step
forward is to become world class.
However, this industry is also the 5th largest energy consumer
and the need is acute to better conserve and manage energy
with minimum ecological impact.
Sonic soot blowing is a low investment, cost effective way of
cleaning the boiler tubes and restore equilibrium conditions to
improve heat absorption and facilitate energy management.p p gy g

4. Most Paper Plants meet its heat and power needs by in‐housep p y
thermal power boilers and waste heat recovery boilers; yet
ineffective removal of ash deposits from boiler tubes have in
many occasions lead to boiler in‐efficiency, capacity reductions,many occasions lead to boiler in efficiency, capacity reductions,
tube overheating failures, and unscheduled shut downs.
Sticky ash in Kraft recovery boilers aside, most ash deposits in
these boilers are friable, less sticky and less tenacious, and are
removable by sonic soot blowing or a combination thereof withremovable by sonic soot blowing or a combination thereof with
existing soot blowing systems in boilers.
So, what is sonic soot blowing and what sets it apart from other
soot blowing systems? Is it feasible to target zero unscheduled
outages through sonic soot blowing?outages through sonic soot blowing?

5. What is sonic soot blowing
Sonic soot blowing is cleaning of
fouled surfaces by compressed air
operated sonic soot blowers.
Sound waves sent inside boilerSound waves sent inside boiler
propagate in all directions and
impart energy to ash particulates
which fluidize and jump up from
Sonic soot blower Tube bundle
which fluidize and jump up from
fouled surfaces to be carried away
by the flue gas stream. Flue gas stream
Cleaning is effective even deep
into tube bundles leaving no dead
corners unclean.

6. Sonic soot blowing cleans with time setting
Sonic soot blowing operates continuously
on‐line in successive short cycles where
Cleaning with time
On
cleaning effect is controlled by cycle time
setting (“on” time is in seconds, and “off”
time is in minutes).
Cleaning with time
A helpful analogy to explain is to imagine
cleaning your table once a year, or once a
Off
month, or everyday. Of course, cleaning
the table daily requires much less effort
to keep it spotless!
Time
Now, apply this to your boiler and clean it
say every 20 minutes, or 90 times a day
i d f j 3 i d ilinstead of just 3 times daily.

8. What is cleaning in successive short cycles
Initially, ash
particulates
land on tube
Since “off” time in the
cleaning cycle is short,
only a small quantity

starts, sound waves
come in and clean up
surfaces and
stay there.
of ash particulates
can land and will
remain quite loose as
there is not enough
easily. The cycle
repeats every few
minutes successively
to keep the tubethere is not enough
time for it to compact.
to keep the tube
surfaces always clean.

9. Pre‐ requisites to operate in successive short cycles
1. It must not cause any damages to boiler
tubes even when the soot blower fails
during operation.
( sonic soot blower never damage tubes)
2. Cost of soot blowing medium must be
low and its production must not leave
l i l f t i tecological footprints.
( compressed air is inexpensive)
3. Soot blowing medium must create no ill
effects at boiler exit.
(compressed air is neutral and friendly)(compressed air is neutral and friendly)

10. 4. Soot blowing equipment must be reliable, easy to maintain, g q p , y ,
and capable of full service between planned outages.
( with only one moving part, sonic soot blower is practically
maintenance free for long term operation) a te a ce ee o o g te ope at o )
5. Soot blowing system investment must be low and payback
period must be short and realizable; and system must be
capable of being installed in new or existing boilers easily. p g g y
(sonic soot blowing system meets these requirements)

13. Sonic soot blowers operate in clusters
Sonic soot blowers are
usually installed on boiler y
LHS and RHS in the tube
bundle service spaces and
operate in clusters to
enhance cleaning effect.

system broadcasts through
loud speaker clusters for
clear transmission to

cases. Constructive interference effect

14. Case 1: Pulp mill 195 t/h recovery boiler
This is a 195 t/h pulp mill recovery
boiler built in 1993 to fire sludge
and with steel ball cleaning system;and with steel ball cleaning system;
it had to be shut down every 3~4
months for manual cleaning.
4 years ago, 16 units of model SB38
sonic soot blowers were installed to
operate in 4 groups. Today, the
sonic soot blowing system runs at
20 sec. “on”/ 3 min. ”off”; and steel
ball cleaning is used only twice a
week for 12 hours and boiler can
last through planned outages. The g p g
client is now a repeat customer.

16. Case 2: Industrial 490 t/h CFBC boiler
This is an industrial 490 t/h coal
fired CFBC boiler built in 2004;
fouling persisted even with LRSB
cleaning and the boiler could only
operate at about 90% MCR.
5 years ago, 40 units of sonic soot
blower models SB60 and SB38blower models SB60 and SB38
were installed and operated in 7
groups. Together with the LRSB
system the boiler returned tosystem the boiler returned to
operate at about 95% MCR.
The client was a repeat customer.

19. Sonic soot blowing system payback period
In most cases and considering benefits from efficiency gains only,
sonic soot blowing system payback period is usually within 2 years.
Any additional benefits from improved performance and reduced
maintenance would further shorten this payback period.maintenance would further shorten this payback period.
