[0002] Boilers that generate steam are called steam boilers, often simply referred to as boilers. They are commonly used in thermal power plants, ships, locomotives, and industrial and mining enterprises. After prolonged use, boilers accumulate a large amount of ash, necessitating soot blowers to remove ash from the furnace and prevent prolonged ash buildup from reducing work efficiency. Chinese Patent No. CN202321902308.6 discloses a special de-heating and pressure-reducing regulating device for steam soot blowers, including an air jet assembly and an regulating assembly. The air jet assembly includes an air guide pipe, a mounting bracket, a first cylinder, and a nozzle. The air guide pipe is fixedly installed at the outlet end of the soot blower, the mounting bracket is fixedly installed on the air guide pipe, and the first cylinder is fixedly installed at the bottom of the mounting bracket, with its output end fixedly connected to the nozzle. The regulating assembly is installed at the outlet end of the air guide pipe and connected to the nozzle. This invention can shorten the distance between the nozzle and the inner wall of the furnace, thereby greatly improving the soot blowing effect. Simultaneously, by controlling the first cylinder to keep the nozzle away from the inner wall of the furnace, the problem of the nozzle being damaged by the high temperature heat of the inner wall of the furnace can be avoided.

[0003] Based on the above, the inventors have discovered the following problems: The combination of the jet assembly and the adjustment assembly in the above patent can greatly improve the soot blowing effect and avoid the problem of the nozzle being damaged by the high temperature heat of the furnace wall.
