Abstract
The present invention relates to a cooling device for preventing fire due to spontaneous combustion of coal stockpiles in a coal-fired power plant, and more specifically, to a cooling device for preventing spontaneous combustion of coal stockpiles, for which a plurality of cooling devices are provided at a predetermined interval in coal stockpiles and, when a temperature (ignition temperature) specified by a user is detected from the outer surface, compressed liquefied nitrogen stored in the cooling device is ejected to lower a temperature around the loaded coal, thereby preventing spontaneous combustion by the oxidation of coal.
