PURPOSE: A plugging prevention system of a pulverulent hopper for industrial facilities is provided to normally operate pulverulent loosening devices by detecting whether or not the hopper is plugged by wet pulverulent bodies beforehand. CONSTITUTION: A plugging prevention system of a pulverulent hopper(100) for industrial facilities comprises multiple pulverulent loosening devices(20), a downstream detecting sensor(10), and a vertical sensor(11). The pulverulent loosening devices are vertically installed on the interior of the pulverulent hopper and vertically move to unplug coals. The downstream detecting sensor is installed in a bottom vertical pipe(120) of the pulverulent hopper to detect the downstream of the coals. The vertical sensor is installed in the upper part of a pulverulent feeding device(110) for measuring and feeding the coals.
