Provided is a coal drying system, and more specifically, a coal drying system using reheat steam comprising: a coal sorting device for sorting coal which has been transported by a coal transport conveyer from a coal yard, and respectively discharging the coal onto a fueling coal transport conveyer and a drying coal transport conveyer; a fluidizing reheater for storing the coal which has been sorted as fuel coal and transported into a fuel coal storage tank, and heating the fuel coal stored in the coal storage tank to a fluidized state and generating reheat steam at a specific temperature; a coal drying device for drying the coal by spraying the reheat steam generated by the fluidizing reheater on the coal, while the coal, which has been transported by the drying coal transport conveyer and passed through a coal distributing conveyer, is transported through multiple steps; and a combustion gas reheater for generating reheat steam at a specific temperature from exhaust gas generated after the coal is dried in the coal drying device by using combustion gas generated in the fluidizing reheater. |
