<p>This fluidized bed dryer achieves improved drying efficiency by: having a hollow drying vessel (101), a raw coal inlet (102) on one end of the drying vessel (101) to introduce raw coal, a dried coal outlet (103) to discharge, from the other end of the drying vessel (101), dried coal obtained by heat drying raw coal, a fluidization gas supply portion (104) that forms a fluidized bed (S) with raw coal by supplying fluidization gas to the lower part of the drying vessel (101), a gas outlet (105) that releases fluidization gas and generated steam from a higher point than the raw coal inlet (102) formed on one end of the drying vessel (101), and a heat transfer tube (106) that heats the raw coal in the fluidized bed (S); and forming the width of the raw coal inlet (102) side of the drying vessel (101) wider than the width of the dried coal outlet (103) side.</p> |
