Industrial Boiler
Sootblowing Systems

Providing a wide variety of soot blowing systems to large coal fired utility plants, recovery boilers in paper mills, waste heat boilers in refineries and petro-chemical plants, and garbage disposal boilers.


VS-C25/C45
sootblower is mainly made up of a traveling carriage, poppet valve, beam, wall box, power cable, front bracket, inner tub, lance, nozzle,
electric box, limit switch control, helix phase change mechanism. The VS-C45 also has an intermediate lance and feed tube support assembly.

Sootblower Structure VS-C2S-C45

The drive train inside the traveling carriage consist of a worm and worm gear set. The worm gear is attached to the end of the main drive shaft. A translation spur gear is also attached to the main drive shaft and this spur gear is engaged with another spur gear located on the pinion shaft directly above. These two spur gears provide the forward and reverse travel of the soot blower. Also, on the main drive shaft are a small bevel which is engaged with a larger bevel gear mounted on the hub. These two bevel gears provide the rotation of the lance tube during traversing. Since there is only one set of bevel gears, the lance tube reverses its rotation of the lance tube in the opposite direction in the reverse travel. In other words, the lance tube rotates clockwise in the forward travel and counterclockwise in the reverse travel.

The “slipping rack” design shown above provides loss motion of the traversing gearing momentarily, while the rotation of the lance tube does not. This design allows the venturi nozzles to be located in a different cleaning position each and every time the soot blower starts its forward travel. Over many different starts of operation the venturi nozzles will return to their intitial starting position so that 360 degree cleaning is obtained.
