The VS is designed specifically for cleaning slag from furnace
walls. It does this by directing a high pressure cleaning medium
(steam or air) through one opposing nozzle onto the furnace
wall. The screw tube delivers the nozzle into the furnace and
then rotates the nozzles. This provides two cleaning sweeps
affectivity covering 100% of the target area.
As with the RW series wall deslaggers, the VS is fully retracted
from the furnace when not in use to protect the nozzle and
screw tube from the high heat conditions found in the furnace.
These sootblower types are sometimes call short retracts.

The VS can be used in negative pressure, positive pressure or
balanced draft furnace conditions. This is accomplished
through the use of different style wallboxes with seal air and air
capabilities. The wallbox is welded to a wall sleeve, which
mounts on the furnace wall and provides the penetration point.
The standard VS is complete with wiring from limit switches and
motor terminating in the electrical enclosure. This electrical
enclosure is also where the reversing motor starters would be
installed for units with integral motor starters. Insertion and
extraction push buttons are mounted in this enclosure for local
operation. Electrical options would include power and control
voltage disconnect and explosion proof enclosures.

The required frequency of operation of the sootblowers will
depend on many factors, such as the nature of the
contamination, gas temperature, fuel, design parameters, etc. It
is required to establish a cleaning cycle practice by checking
the fouling of the heating surfaces visually, and monitoring gas
temperatures and pressure changes. If the cleaning effect is
not sufficient, the blowing frequency, and/or the blowing
pressure, can be adjusted. In the event that certain areas are
not sufficiently cleaned, those responsible sootblowers may be
addressed individually. Since the sootblower’s blowing jets
often have an are erosive effect if dust or ash is present, it is
recommended that these surfaces be checked regularly for
erosion. Blowing pressure should be reduced if damage is
found.

Rotary Sootblowers

The Clyde Bergemann Model D5E (Electric) and D5M (Manual)
Rotary Sootblowers offer dependability in boiler cleaning and
ease in operation. The D5 Rotary has been part of the Copes
Vulcan (Sootblower Division purchased By Clyde Bergemann in
1997) product line for many years with thousands of units
providing excellent service worldwide. The D5 Rotary features
a simple design concept, which equates to minimal
maintenance cost and trouble free operation.
The Clyde Bergemann Model D5 rotary sootblower is designed
to clean convection surfaces of packaged or field erected
industrial boilers. The blowing element of this type sootblower
remains in the boiler at all times, supported by element
bearings usually attached to the boiler tubes. Specially
designed nozzles are located on the element (as required) for
each specific installation. Saturated or superheated steam, as
well as compressed air, may be used as the blowing medium.
The D5 can operate in temperatures up to 1800 F with the
proper choice of element material. To prevent infiltration of
corrosive furnace gases through the element to the valve
assembly, a scavenging air check valve is furnished as
standard equipment on the D5 rotary sootblower. For
pressurized furnaces a purging airline from a source of higher
pressure than the furnace is connected to the scavenging air
valve.
We have a wide range of materials available to meet the
requirement for any application, from plain carbon steel, to high
temperature alloys such as HR-160. Element sizes are 1 ½”
and 2” pipe. Element support bearings in matching materials
will be supplied.The sootblower can be configured for full or
partial blowing rotation in either a clockwise or counter
clockwise direction

Model RKTT

The RKTT dual medium cleaner is a specifically designed multi-
function rake blower for Air Preheater duty. A multi purpose
nozzle design allows for three modes of operation namely (1)
Steam/Air (2) Low-Pressure Water (3) High Pressure Water.
The normal mode of operation is using High Pressure Steam.
Low and High Pressure Waters are used when operationally
required.Steam or air is used for this on line cleaning. Low
pressure water could also be delivered through the element
nozzles for basket washing.
The RKTT is different to the RKT in that it has the ability to
supply a third cleaning medium, high pressure water. The
RKTT is used in more sever cleaning applications such as
those found following and SCR or SNCR installation where this
high pressure water is required to remove sticky deposits. In
addition to removing these sticky deposits the RKTT cleaner
can be used to eliminate or minimize the need for off line water
washing.

Jet Blowers

The Clyde Bergemann Jet Blower is a unit designed specifically
for multi medium cleaning, utilizing a different style lance than
the RKTT described above. The jet blower utilizes a straight
line (non rotating) lance with a cluster of six nozzles. The basic
principle is the same, clean with steam or air while the boiler is
online and then switch to pressure water online when normal
cleaning is not enough and low pressure water wash offline
during a shutdown.
A gauge panel is included on the unit for local reading of the
cleaning media as well as pressure switches for local
indications that can be transmitted to the controlling PLC. All
other great features of the Clyde Bergemann retractable
sootblower line are shared here as well


SmartLance ™ Cleans with Steam or Water:

Many boiler operators firing heavy fouling fuels have trouble
keeping super heater surfaces from forming sintered deposits.
These often cannot be removed with regular retracts using
steam or air as cleaning medium. On the other hand the regular
use of water lances is prohibitive because they too often cause
unacceptable levels of tube damage. Clyde Bergemann’s Multi
Media SmartLance now offers a new solution: It is a retractable
sootblower that normally cleans with steam, however, if and
when necessary allows the operator to perform a special
cleaning cycle during which water is blended into the cleaning
stream in controlled amounts to remove any slag build up.
When using water the Multi Media SmartLance is designed to
keep the thermal impact on the boiler tubes at a minimum by
controlling the amount of water that is being applied to the
heating surfaces.
In order to ensure optimal cleaning effect and minimal thermal
impact during cleaning using water, the SmartLance™ has
been designed with two sets of water blowing nozzles. During
the insertion cycle, the lead (forward pointing) water nozzles
are activated by a solenoid valve supplying water to the
relevant inlet at the rotating seal. The jet progression velocity
(path speed of water across the pendant tube surface) is hence
maintained at the optimal level where both jets impinge.
Likewise, during the retraction cycle, the rear-facing (lag)
nozzles are activated to clean the opposite side of the pendants
in the relevant section being cleaned. The use of dual lead and
dual lag nozzles is a necessity for effective and controlled water
cleaning for these reasons.
SmartLance™- A SmartClean™ Product The SmartLanceTM is
offered as part of Clyde Bergemann’s SmartClean Boiler
Cleaning Optimization System. SmartClean will make the
decision which cleaning medium is best to use based on the
actual cleanliness of the heating surfaces. The Multi Media
SmartLance is the most effective AND SAFEST cleaning tool
available for heavy-plugging super heaters.

Wall blowers(Type V04 Clyde Bergemann)
Blower is bolted to front plate of negative pr wall box.
Run command given. Blower moves forward .Blower reaches
blowing position.Blower steam valve opens.Blower rotates as
per set blowing arc .After completion of rotations blower steam
valve closes. Blower returns to home position. What is the role
of front limit switch ? .At front end of blower is nozzle head
having two opposite venturi nozzles. At home position nozzle
head is in protecting wall box. Track beam is basic iron
frame.Motor is flanged to a spur gear drive on the track
beam.Screw tube is welded to nozzle head.Rotational motion of
motor is transmitted to screw tube via chain wheels and a
chain. Rotaional motion of screw tube is translated in to axial
motion of blower by means of a threaded screw nut and guide
placed in track beam.At blowing position , screw tube has
screws itself fully in to screw nut and guide and screw tube are
no longer meshing and .So no conversion of rotational motion
in to axial motion and blower rotates.The screw tube moves
alonf fixed feed tube.Stuffing box at the rear end of screw tube
seals annular space between screw tube and feed tube and
prevents leakage of blowing steam. Stuffing box requires
tightening after blower has operated few times.Retightening is
to be done in case of leakage.If retightening does not stop
leakge , more packing rings should be inserted, other wise
replace stuffing box .Stop disc fitted to the casing of stuffing
box actuates blower steam valve.Throttle disc in the blower
steam valve is used to adjust blowing steam pr.At the end of
forward travel ,rotational motion of screw tube actuates
engaging lever which operates valve lever and which in turn
depresses valve stem and valve is opened.Vent valve remains
open when steam valve is closed.negative furnace pr causes
continuous flow of air from atmosphere into furnace through
blower and prevents entry of flue gases in to nozzle head.Vent
valve is closed by the pr of steam when steam valve is opened.
Soot blowing can not be done if blowing steam pr is
inadequate.An operating blower is retracted if blowing steam pr
falls below limit.
Long retractable blower (type PS-SL Clyde Bergemann)
Vent valve and stuffing box are provided. At the front end of
lance tube is nozzle head having two venture nozzles.The rear
end of lance tube is flanged to lance hub and front end is in
lance tube guide.In rest position , nozzle head is in wall
box.Sliding plate of wall box seals the entry of lance tube
through the boiler wall.The spur gear driven by motor has two
output shafts.The drive pinion engaged with toothed rack of
track beam is on one shaft(axial shaft) and moves blower
axially.The other shaft (rotary shaft) causes rotation of lance
tube through chain drive.The lance tube moves helically while
advancing.Rear end of feed tube is fastened to a T cross piece
and its front end is in lance tube.Steam valve is connected to
this T cross piece.Steam pr control disc is in steam valve.The
opening and closing of steam valve can be adjusted by
adjusting position of trip pin on perforated bar so that steam
valve is opened after nozzles have passed boiler wall while
advancing and is closed before npzzles reach boiler wall so
that blowing steam does not damage boiler wall.the adjustable
retaining bolt on the punched strip is engaged with cam
plate.Cam plate is connected to steam valve lever by means of
tie rod.
APH soot blowers( Type PS-AT Clyde Bergemann)
Lance tube has three venture nozzles. Spur gear has only one
output shaft(axial shaft) and so no helical movement of lance
tube while moving. Lance tube moves forward in steps and
continuously retracts.Lance tube guide is at front end of track
beam to guide and support lance tube. Other things same as
that of other blowers
