Steam Sootblower
Pros:
1. More effective removal of soot at generating bank
2. Less maintenance (soot blower lance to take care only)
Cons:
1. Steam usage
2. Possibility to erode tubes if wrong installation method
Sonic Sootblower
Pros:
1. Alternative solution for soot removal
2. Can be equipped at Air Preheater or Economizer location where steam soot hardly to be applied
3. Dry solution, won't damage tubes
Cons:
1. Less effective compare to steam soot as using soundwave
2. More maintenance cost (diaphragm plate, solenoid valve, compressor, relay, timer, etc) to take care.
Conclusion
We have operated this Sonic Sootblower for 14 years and we would recommend to use sonic soot blower because steam soot blower only used on an 8-12 hour cycle thus allowing the ash to build up and allowed to reside on hot tube surfaces. By using sonic soot blower, ash will be removed continuously and envelop the entire circumference of each tube without causing damage to the tubes and structure. Moreover sound wave does not cause erosion and corrosion.
