FIELD: metallurgy.
SUBSTANCE: invention relates to storage of bulk materials and can be used as coal bin storage for metallurgical enterprise. Bin storage includes coal silos, each of which consists of cylindrical part and conical funnel, in lower part of which there is a coal drawing device common conveyor for supply of coal for processing, that is connected to yields of coal drawing means. In silos, in the area of joint of cylindrical part and conical funnel, in three equidistant points temperature sensors are installed, which are connected to a temperature meter. Coal storage is equipped with inert deterrent feed system and water feed system for cooling of coal. At that nozzles to feed inert deterrent are installed in silos in the area of joint of cylindrical part and conical funnel at the points, equidistant from temperature sensors, and water feed nozzles are installed in groups under the corresponding silos along total conveyor for supply of coal for processing.
EFFECT: technical result consists in preventing coal self-ignition in coal silo storage without stopping the process of coal supply for further processing.
