Case analysis of pneumatic conveying pipe blockage

During the use of the fuel pneumatic conveying system for sintering in a certain ironworks, the large particle size, high moisture content, and poor flowability of the coke powder caused significant resistance in the pipeline. In addition, the insufficient conveying output resulted in a gradual decrease in the conveying speed of the coke powder in the pipeline, causing frequent pipe blockages Improvement measures have been proposed to address the causes of pipe blockage. The ash intake pipe has been modified by extending it into the bin pump and designing a section of Venturi tube at the front end of the ash intake pipe. At the same time
