CLEANING PERFORMANCE COMPARISON

Soot Gone

High cleaning performance:

Soot Gone™ is more effective than other alternatives. Each Pulse Generator can clean a rel
  • The velocity of the hot and dry wave produced by Soot Gone™  is about  3MACH (1300m/sec)

  • The wave duration is milliseconds.

  • The mass of  blast wave created by Pulse Generator  is insignificant: about 80 grams omnidirectionally. 

Why is the Soot Gone™ effective and harmless to the boiler?

The low mass and high velocity of the omnidirectional wave-pulse generated from the detonation is the source of Soot Gone™ effectiveness in boiler cleaning.

The physical meaning of pulse is:   F x T = M x V 

(F-force;   T-time;  M-mass;   V-velocity)

Such pulses are effective in cleaning and harmless to the tubes, refractories and boiler structure.

An impulse wave spreads in the boiler volume omnidirectionally  and removes the ash from the heat-transfer surfaces circumferentially. 
Soot Gone™ is more effective than other alternatives. Each Pulse Generator can clean a relatively large area and reach areas inaccessible to conventional soot blowers.   

Steam Soot Blower

Low Cleaning Performance:

Traditional steam soot blowing technology is restricted to line-of-sight cleaning
  • The velocity of steam jets is about 25m/sec

  • Conventional steam soot blowing technology is restricted to line-of-sight cleaning.

Steam potentially introduces excessive moisture and condensation in the boiler, with accompanying damage to the pipes, supports, and refractories (thermos shock phenomena). 

APPLICABILITY COMPARISON

The Soot Gone™ system can be applicable in areas:

  • Evaporators

  • Economizers 

  • Superheaters 

  • Air preheaters

  • Ducts 

  • Hoppers 

  • Chimneys  

The  hot blast wave  of supersonic velocities and relatively long distance effect makes it possible to clean ducts, hoppers and chimneys from deposits avoiding refractories damaging.

  • Hard to reach areas . 

The installation flexibility  due to its small footprint  allows  Soot Gone™ to be installed in a variety of locations, including hard-to-reach areas.

The Soot Gone™ system can be applicable for removal of sedimentation types :

  • Ash

  • Soot

  • Slag 

  • Cement 

  • Lime 

  • Pigments 

  • Additives 

  • Fertilizers, etc.
     

Soot Gone™ operates with hot and dry gases, that is why it can be applicable to clean the surfaces from different powder deposits like pigments, additive products, cement, lime, etc., where moisture is unacceptable. 

Steam Soot Blower can be applicable for removal of sedimentation types :

  • Ash

  • Soot

  • Slag 

Not applicable for cleaning of cement, lime, pigments, additives, fertilizers.

Contact of such materials with steam  leads to sintering and other undesirable phenomena.

Steam Soot Blower is applicable in areas:

  • Economizers 

  • Superheaters 

  • Air preheaters

Not applicable in ducts, hoppers, and chimneys.

High humidity short distance steam jets are inefficient and cause thermal shocks and slag sintering. 

Limited installation and use in hard-to-reach areas due to significant dimensions of Steam Soot Blowers with their huge service platforms. 

The Soot Gone™ system can be applicable in  corrosive environments.

There's no wear and tear in Soot Gone™ due to the fact that it is outside the boiler.

Steam Soot Blower  is not applicable in corrosive environments.

Steam Soot Blower's lance traverses inside the boiler which leads to its rapid erosion and corrosion.

INSTALLATION COST

   High installation cost:

  • requires large service platforms spaces;

  • requires laying cables along the walls of boilers.

     Low installation cost:

  • compact;

  • no need in wide service platforms;

  • no need for electrical or instrumentation cables on boiler body;

  • flexible and easy in installation.

MAINTENANCE COST

Low maintenance cost:

  • no moving parts-static device;

  • no internal components inside the boiler;

  • almost no need in spare parts in the stock; 

  • high level of reliability.

 High maintenance cost:

  • wear items: housing, gearbox seals, 
    feed tubes, blown and damaged nozzles, 
    worm and damaged carriage housing, 
    warped, melted and corroded lance tubes, 
    entangled cable and power cords, worn and failed gearbox seals, corroded feed tubes, motors and gears, steam traps, packing tensioner, etc.  

  • A great amount of spare parts is needed in stock which value reaches hundreds of thousands of $.  

BOILER DAMAGE

 Steam Soot Blower

Operating ​Soot Gone™ doesn't damage the boiler.

The actuating medium is hot flue gases. 

No moisture or condensate is injected inside the boiler.

The mass of  blast wave created by Pulse Generator is insignificant: about 80 grams omnidirectionally. 

Such high velocity low mass pulses are effective in cleaning and harmless for the tubes, refractories and boiler structure.  

Operating Steam Soot Blower can damage the boiler:
 

  • high steam humidity causes the thermal shock and corrosion in boiler structure and refractories;

  • pipe’s additional corrosion inside the boiler; 

  • refractory ‘s erosion;  

  • boiler structure damage; 

  • damage to the boiler pipe supports;

  • ash deposit accumulation.
