Comparison between air shock wave soot blower and gas pulse soot blower

1. The soot removal effect is obvious (better than the soot blowing effect of gas shock wave soot blower), which can reduce the flue gas resistance and exhaust gas temperature when acting on the heating surface with soot deposition. Mechanical level meter

2. Since the pressure of compressed air is 0.8-1.0MPa higher than the deflagration pressure of gas soot blower is 0.6-0.8MPa, the energy of shock wave generated is larger, and the rotating nozzle can effectively increase the action area, so the effective range of soot cleaning is larger and more thorough, leaving no dead angle for soot blowing.

3. Online ash removal, once per shift, only 6 times per mouth, about 12-18 minutes.

4. It is very convenient to use the compressed air owned by the power plant or 1.25MPa air compressor.

5. Non combustible gas is used to overcome the potential safety hazard caused by gas shock soot blower system leakage or furnace flue gas backflow.

6. It has a wide range of applications. The gas energy pulse shock wave soot blower can be applied to all areas including the high-temperature superheater, and is not affected by the temperature in the high-temperature section and the positive pressure fluctuation of the furnace body.

7. It is simpler than other soot blower systems, including a set of control system, a set of compressed air distribution pipeline, an air compressor, and a shock generator

8. The operating cost and investment are low, and the operating cost and investment are lower than those of all current soot blowers on a year-on-year basis.

9. Low failure rate: 1. Due to the different structure from the gas shock soot blower, the lower end of the shock generator is sealed, and it will not generate ash when it is not used at ordinary times; 2. The system is simplified, and there is no combustible gas supply device, and no combustible gas distribution ignition device; 3. The control part is simplified, safe and reliable.
