It would be better if there are related books. Thank you in advance.
The sonic soot blower technology converts compressed air (or steam) into high-power sound waves (a pressure wave that propagates in the space medium (gas) in the form of density waves) and sends it into the furnace. When the soot on the heating surface is repeatedly pulled and pressed by alternating density waves with a certain frequency, it loosens and falls off due to fatigue and is carried away with the flue gas flow, or sinks to the ash hopper under the action of gravity and is discharged. During the production and operation of the boiler, dust and slagging accumulate on the heating surfaces of the boiler - water wall, superheater, economizer, preheater and flue. This is a problem that has long plagued production and is difficult to solve. It not only weakens the heat transfer on the heating surface of the boiler, reduces the thermal efficiency of the boiler and reduces the production load, but also may lead to unexpected shutdown of the boiler when the heating surface is seriously ash and slagging, causing significant economic losses. At present, most boilers are equipped with steam sootblowers, compressed air sootblowers, steel ball sootblowers, etc. However, in terms of operation and performance, these traditional sootblowers have disadvantages such as limited sootblowing range, blind spots for sootblowing, high energy consumption, high maintenance costs, inconvenient operation, and side effects. The utilization rate is very low, and most of them are parked and not used. Therefore, new technologies must be sought to remove dust from the boiler heating area and prevent slagging. In the 1970s, Swedes first discovered and used low-frequency acoustic wave cleaning technology for boilers, which opened up a new way for boiler cleaning. It has been widely used and achieved good results. Gas shock wave soot blower http://bbs.hcbbs.com/viewthread.php?tid=90783&highlight=%C8%BC%C6%F8%BC%A4%B2%A8%B4%B5%BB%D2%C6%F7
