for industry boilers and heaters

Online Super Effective Cleaning of Industrial Boilers and Heaters –
Patented System

 

Currently installed in Waste to Energy Plant in Israel,the patented Soot Gone™ uses LeonPulse technology to clean the surfaces of industrial boilers that are caked with ash, soot and slag. Soot Gone™ costs an order of magnitude less than alternatives to install and operate and is low maintenance as well.

 

Provide super effective omnidirectional soot blowing.

Has no retractable tubes lances. Easy to install, is adaptable and compact. Small footprint. Requires minimal maintenance. Safe with any fuel burning equipment, preserves long term boiler integrity. Has, by an order of magnitude, lower capital, maintenance and operating costs than the alternatives. Meets safety codes and standards. Can be fully automatically or manual operated. Patented.

The description of the technical problem.

The build-up (fouling) phenomenon of combustion by-products on the walls of the pipes, including fine carbon, ash, soot, and slag on the screens, superheaters, air preheaters, economizers and other heat transfer surfaces causes two main problems:

1. The Significant Decreasing of Boiler’s efficiency. The flue (hot) gases are unable to transfer heat energy to water or steam in the boiler, and hence considerable part of energy is going to the stack.

2. The Significant Capacity Decreasing. The dramatically arising of boiler’s aerodynamics resistance in flue gas path because of the fouling or, in other words, because of a High Pressure ifferentials, leads to the shortage of supplied combustion air and, hence, lower heat capacity together with non-complete combustion occurred. The non-complete combustion yields in its turn additional growing of the fouling in the boilers. Because of the aerodynamics resistance the air blower’s electricity consumption (the air supply to the burners) will also arise.

The accumulation of buildup (fouling) causes heat generating facilities (boilers or heaters) to operate significantly less designed efficiency and capacity with increasing of pollution emissions.

 

Economic losses caused by boiler fouling and subsequent more frequent plant shutdowns have reached unacceptable levels therefore.
Shortcomings of traditional on-line cleaning systems, such as steam or air soot blowers, sonic horns etc. bring to non-planned shutdowns for manual cleaning of boilers that is the hardest, dirty, expensive and harmful operation. Read more

Soot Blower SOOT GONE ™ is the new approach and solution for the following industrial plants where part of technologies is based on combustion processes:

  • Waste-To-Energy (WTE) and Sludge Incinerating Plants
  • Hazardous waste incineration plants
  • Fossil ( Oil, Coal, Shales etc.,)Fuel Power Stations
  • Chemical Plants
  • Oil Refineries
  • Cement Plants
  • Incinerators
  • Pulp and Paper Mills (Black Liquor Boilers)
  • Filters and Spray Absorbers
  • Metallurgic factories

 

Typical Soot Gone Implementation at Waste to Energy plant

 

 

 

Soot Gone ™ Pulse Cleaning based on detonation (pulse) phenomenon and is starting to be specified as a product of choice to replace conventional soot blowers throughout the world.

 

The “Soot Gone” may be a superior method for cleaning in semi-radiant and convectional heat-transfer surfaces such as:

  • economizer
  • steam- superheater
  • other tube bundles
  • air-preheater
  • It can be used for cleaning Ljunstrom or Rothemuhle lamellar rotary regenerative air preheaters as well.

 

Soot Gone™ comprised from:

 

  • Air supply
  • Gas supply
  • Air – Gas mixer
  • Ignition chamber
  • Manifold
  • Pulse Generator

 

 

The procedure of Soot Gone™ cleaning process

 

  • Filling the Soot Gone™ system with a gas-air mixture providing by front flame generator.
  • Igniting the mixture and creating the deflagration burning.
  • Propagating the deflagration through conduit pipe to.
  • Creating the Pulse in Soot Gone™ cannon.
  • These aforesaid steps are performed repeatedly

 

Effective cleaning

 

 

The device “Soot Gone” is characterized by its following features:

Detonation cleaning provides a cleaning blast wave that is omnidirectional, propagating through the entire tube assembly whereas soot steam soot blower technology is restricted to line-of-site cleaning.

 

The three keys to the efficiency of the blast wave cleaning

1. Velocity, 2. Reflection, 3. Reverberation

The reported advantages of pulse impact cleaning are the ability to remove harder deposits as well as loose slag and ash. Each Pulse Generator combustor can clean a relatively large area and reach areas inaccessible to conventional soot blowers. Maintenance is significantly reduced compared to conventional soot blowers.

 

The Soot Gone™ device is characterized by following outstanding features:

 

  • Super effective
  • Compact & Very light weight, can be installed in arduous places
  • Low capital and installation cost
  • Very low operation and maintenance cost
  • Required utilities:
    ambient air and low pressure (2 Bar) fuel gas
  • Safe for the pipes, structure, refractories of the boiler
  • Safe for the staff and environment.

  • No need in electrical or instrumentation cables along the boiler itself
  • No need in huge service platforms installed on the structure of steam generators
  • Almost no spare parts, no spares in stock are needed

 

 

 

Impulse wave removes the ash from the heat-transfer surfaces circumferentially.

 

 

Traditional steam soot blowing technology is restricted to line-of-sight cleaning

The actuating fluid is hot flue gas combustion exhausted from pulse generator.

Safety and Control

 

It is of a great importance for our team the safety of the Soot Gone™ Pulse Generator technology.

1. The Soot Gone™ Pulse Generator is safe and harmless

2. The Soot Gone™ procedure is based on the low pressures technology (The operation LPG pressure is 1.0 bar and compressed ambient air pressure is up to 0.5 bar.)

3. Installation of gas distribution according to local regulation

4. Loudness of pulse bang outside of the boiler approx. 50 dB, short peak

5. No danger to create leaks in boiler tubes because of impact pulses provided by Soot Gone™ pulse generators.

6. The Soot Gone™ can be operated manually or can be fully automated.
