NOVELTY - The dryer (1) has a storage container (6) storing a moisture fuel. A heating unit heats the moisture fuel. A purge medium for removing non-condensable gas mixed with moisture fuel towards the stored moisture fuel is supplied. A purge medium supply unit (42) makes the moisture fuel to flow with the supplied medium. A dry container (7) is provided in which a fluidized bed is formed in an inside while the stored moisture fuel is supplied and the supplied moisture fuel flows by fluidization gas. The moisture fuel is stored by an upward side along a perpendicular direction of a purge pipe (45).    USE - Fluidized bed dryer for use in a gasification composite power generation equipment (claimed) i.e. integrated coal gasification combined cycle power generation apparatus, of an air combustion system to heat-dry moisture fuel i.e. wood coal, to be supplied to a gasifier. Can also be used for a biomass, coppiced timber, waste material wood, driftwood, grass, waste material, sludge, tire, and recycle fuel.    ADVANTAGE - The non-condensable gas mixed while making the wood coal to flow with the purge vapor, which heats the wood coal with the heating tube, and is supplied from the purge medium supply part that is removable so as to make the wood coal to be hard to make high temperature in a supply side of the wood coal of a dry container, so that mixing of the non-condensable gas into the dryer can be suppressed, and water vapor can be collected efficiently when utilizing the water vapor emitted from the dryer.    DETAILED DESCRIPTION - The heating unit is a heating tube (41). INDEPENDENT CLAIMS are also included for the following:    (1) a gasification composite power generation equipment    (2) a drying method.
