Abstract: PURPOSE:To prevent dust explosion, by previously purging the interior of a coal storage tank with nitrogen, and then both throwing coal into the tank and detecting concentration and pressure of oxygen in ambient gas, then controlling a supply quantity of nitrogen gas on the basis of the detected pressure. CONSTITUTION:Before coal is stored in a coal storage tank 1, nitrogen gas is supplied from a nitrogen gas injection port 14 to perform nitrogen purge internally of the tank 1.
