PROBLEM TO BE SOLVED: To provide a drying system capable of suppressing condensation of wet fuel such as brown coal, and capable of suitably making the wet fuel flow.SOLUTION: A drying system includes: a fluidized bed drier 11 drying brown coal while forming a fluidized bed 18 inside thereof by making the brown coal supplied into the inside flow by fluidized steam; and a preheating device 10 preheating the brown coal to be supplied to the fluidized bed drier 11. The preheating device 10 preheats the brown coal while forming a fluidized bed 15 inside thereof by making the brown coal supplied into the inside thereof flow by fluidized gas. At this time, non-condensable gas is supplied as the fluidized gas to the preheating device 10. |
