What are the different methods for cleaning furnace tubes? What are its advantages and disadvantages?

What methods are used, both domestically and internationally, for cleaning ash accumulation from boiler tubes? What are its advantages and disadvantages? Which one is better?
Currently, the most widely used and effective method for ash removal from boilers is pneumatic ash removal.
There are generally three methods for removing ash from boilers: first, steam cleaning; second, air cleaning; third, using chemicals such as descaling agents to remove ash. In terms of effectiveness, steam and air are similar, but since steam has a higher temperature and high-pressure steam is easily available, steam cleaning is more effective than air cleaning； Dust removal agents can be used as an auxiliary method, in conjunction with steam cleaning.
Who is familiar with the \"LPG micro-explosion dust removal process\"?
The liquefied gas micro-explosion dust removal process has not been used for cleaning furnace tubes, but a similar device was employed in the Cabot carbon black project. Since the particle size of carbon black after passing through the carbon black reaction furnace is extremely small, it tends to accumulate on the walls of the transport pipes; therefore, a small device called a \"banger\" is installed inside the pipes. A literal translation is firecrackers. Liquefied gas is introduced, and piezoelectric ceramics are used to ignite it at a certain frequency; the resulting deflagration generates shock waves that dislodge the carbon black dust adhering to the tube walls. I hope the above experiences can be helpful to those above
