abstract="In order to explore the propagation characteristics of explosion and combustion flame of the benzene vapor, explosion and combustion experiments of different concentrations of benzene vapor were carried out in a self-designed 1m transparent explosion test pipeline. The high-speed camera was used to capture images of flame propagation of benzene vapor explosion in the pipeline. The flame images were compared and analyzed. The results show that a violent explosion reaction occurs when the low concentration of premixed benzene vapor-air gases are ignited, and the violent explosion reaction turns into a mild combustion reaction with the increase of concentration of benzene vapor in the premixed gases. The average flame propagation velocity increases with the rise of benzene vapor concentration, and reaches a maximum when the volume fraction of benzene vapor is 2. 8%. Then the velocity decreases with increasing benzene vapor concentration. The propagation process of explosion flame of low concentration benzene vapor can be divided into four stages: a rapid accelerating stage, a rapid decelerating stage, a slow accelerating stage and a slow decelerating stage. The propagation speed of high-concentration benzene vapor flame basically keeps constant, and the flame shape is closely related to flame propagation speed. © 2019 China Safety Science Journal<p /><p>Language: zh</p>",
