Description

Technical Field

[0001] The utility model belongs to the technical field of steam soot blowers and relates to a steam soot blower equipped with an air output volume regulating structure. Background Art

[0002] The working principle of the steam soot blower mainly relies on high-temperature and high-pressure steam. When the steam flows through the continuously changing rotating nozzle, it will be ejected at high speed, generating a large impact force. This impact force can effectively blow off the ash deposits on the heating surface and carry them away with the flue gas, thereby achieving the purpose of removing the ash deposits. The steam soot blower plays a vital role in the boiler system. Its main function is to remove the ash deposits on the heating surface by ejecting high-temperature and high-pressure steam at high speed to ensure the efficient and safe operation of the boiler. However, when the steam soot blower cannot quickly adjust the steam output, it may cause a series of problems, which not only affect the operating efficiency of the boiler, but also pose a threat to the safety of the equipment.

[0003] The instability of steam output will directly affect the soot blowing effect. If the steam output is too small, the soot on the heating surface may not be effectively removed, resulting in a decrease in the heat transfer efficiency of the boiler and increased energy waste. On the contrary, if the steam output is too large, the heating surface may be over-washed, causing increased wear of the heating surface and shortening the service life of the equipment. Therefore, a steam soot blower equipped with an output adjustment structure is urgently needed to solve the above problems. Summary of the invention
