摘要
The present invention relates to an apparatus for improving, in a multi-stage dryer for drying coal using reheat steam, drying efficiency by controlling reheat steam so as to be injected at a certain pressure into coal which is inputted onto a transfer device and is transferred thereby. The present invention relates to an apparatus for drying coal using reheat steam, the apparatus being configured so that coal which has been dried primarily in a first coal dryer is inputted into a second coal dryer and thus is secondarily dried, wherein steam supply pipes for supplying reheat steam generated from a reheater are connected to one side of each of a first steam chamber, a second steam chamber, a third steam chamber and a fourth steam chamber, and wherein first steam distribution perforated plates, which have a plurality of first steam injection holes formed therethrough, are combinedly installed on the upper section of the inside of each of the first steam chamber, the second steam chamber, the third steam chamber and the fourth steam chamber so that reheat steam having a uniform pressure is injected through the first steam injection holes.
