Steam SootblowerPros:1. More effective removal of soot at generating bank2. Less maintenance (soot blower lance to take care only)Cons:1. Steam usage2. Possibility to erode tubes if wrong installation methodSonic SootblowerPros:1. Alternative solution for soot removal2. Can be equipped at Air Preheater or Economizer location where steam soot hardly to be applied3. Dry solution, won't damage tubesCons:1. Less effective compare to steam soot as using soundwave2. More maintenance cost (diaphragm plate, solenoid valve, compressor, relay, timer, etc) to take care.ConclusionWe 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.
Thank you Mr. Chang for sharing of your experiences. This is valuable experience not found in book or rarely in Google. This is exactly what this forum for - sharing of our hard earned experience amongst members, the PalmIngenieurs.
My experience in steam soot and sonic soot in Palm Oil Mills My first soot blower is rotary steam soot boiler install in Fraser water tube boiler 1985，after few year of operation, one day we found bundle of boiler tube leak only we know that our rotary valve pin broken and steam soot is not rotating, shooting at same place and damaged heat generation tube, second problem of steam soot during daytime operation, black smoke we call black dragon flying out from chimney, facing DOE problem, so we only clean our boiler at night. 1991, we bought new boiler, agreed with boiler supplier install sonic soot blower, sound good, no water, no erosion, corrosion or mechanical wear, stay clean with sound, but after some time, we found our boiler badly choked with ash, sonic soot blower not working? The answer is boiler supplier give us a undersized air compressor with very small air receiver tank, after few blow the compressor air pressure drop and flow not enough to vibrant sonic, by changing bigger compressor with additional air receiver tank, sonic soot working well, from my experience, regular maintenance, replacement of sonic diaphragm is very important, from the sound of sonic soot blower you can feel efficiency of your sonicLast year we bought new boiler, 70 ton couple with steam soot and sonic soot blower, we think combine two May be the best 😜😝😛
