FIELD: heating.
SUBSTANCE: invention refers to soot blowing device for cleaning of boilers in operation, and namely for cleaning of heat transfer devices located in boilers by means of gaseous and/or liquid cleaning medium, such as steam and/or water stream. Soot blowing device includes blowing pipe moved in axial direction, which is equipped on its working end with side outlet nozzles. In order to provide safe connection of pipeline to the blowing pipe at lower costs, supply pipeline can consist at least of two practically straight-line stiff sections of pipeline, which are connected to each other through hinged connection of the pipeline. The pipeline section that forms the pipeline end is connected through hinged connection of the pipeline to inlet end of blowing pipe, while the pipeline section that forms the pipeline beginning is connected through the hinged connection of pipeline to connecting branch pipe of the stationary system of cleaning medium pipelines. Rotation axes of all hinged connections of the pipeline are located parallel to each other and are almost vertical.
EFFECT: cleaning efficiency improvement.
