Working principle:

Gas pulse shock soot blower works by mixing air and flammable gas (such as acetylene, liquefied gas, hydrogen, etc.) in a special container in a proper proportion. After high-frequency ignition, it produces a deflagration, which instantly produces huge energy oscillation. The energy can be a shock wave that hits and sweeps the surfaces of the tube bundle. This action can lead to the surface areas’ ash flying, then the wave can carry the smoke away.

Main form: 

According to the setting position of the gas mixing point, it generally can be divided into two types: theserial type and the parallel type. The tandem system means that the gas mixing point is arranged on the main pipeline;whereas the parallel system means that the gas mixing point is arranged on the branch pipeline of each soot blowing. Thus, after turning on the igniter,the high temperature gas is generated and directly transferred to each soot blowing. In terms of system settings, the parallel type is more secure and more flexible than the series system.

 Technical performance characteristics:

  The gas pulse shock soot blower is mainly composed of a gas supply system, a main air supply system, a gas mixing tank, an igniter, a shock energy distribution system, a shock generator and shock tube, etc.

 Advantages:

• Suitable for purging loose ash especially in the low temperature area of ​​the tail flue.
• The system is simple and only takes up small space.

• Disadvantages:

• Gas consumption is high, need regular replacement of gas supply equipment.
• Purging is not 100%, may leavesome dead corners to further purge.
• Due to the use of flammable and explosive gases, the safety risk is greater.
