Description

Technical Field

[0001] The utility model relates to the technical field of boiler sootblowing, in particular to a sootblower for a power plant boiler. Background Art

[0002] The primary purpose of a power plant boiler is to generate electricity. These boilers release heat energy by burning fuels (such as coal, oil, and natural gas), heating water into high-temperature, high-pressure steam. This steam is then used to drive a steam turbine, which in turn drives a generator, generating electricity.

[0003] When a power plant boiler is used for a long time, it is necessary to regularly clean the outer surface of the heating surface of the boiler to avoid dust accumulation and improve the thermal efficiency of the boiler. However, when using the existing soot blower to blow soot in the power plant boiler, it is not convenient to rotate the soot blowing pipe, which leads to a limited soot blowing range and dead angles, thereby reducing the soot removal effect. In response to the above problems, the inventors proposed a power plant boiler soot blower to solve the above problems. Utility Model Content
