The present invention provides a fuel gasification furnace including a gasification chamber ( 1 ) for fluidizing a high-temperature fluidizing medium therein to form a gasification chamber fluidized bed having an interface, and for gasifying a fuel in the gasification chamber fluidized bed, a char combustion chamber ( 2 ) for fluidizing a high-temperature fluidizing medium therein to form a char combustion chamber fluidized bed having an interface, and for combusting char generated by gasification in the gasification chamber ( 1 ) in the char combustion chamber fluidized bed to heat the fluidizing medium, and a first energy recovery device ( 109 ) for using gases generated by the gasification chamber ( 1 ) as a fuel. The gasification chamber ( 1 ) and the char combustion chamber ( 2 ) are integrated with each other. The gasification chamber ( 1 ) and the char combustion chamber ( 2 ) are divided from each other by a first partition wall ( 15 ) for preventing gases from flowing therebetween, and which extends vertically upward from the interfaces of the respective fluidized beds. The first partition wall ( 15 ) has a first opening ( 25 ) provided in a lower portion thereof, and the first opening ( 25 ) serves as a communication between the gasification chamber ( 1 ) and the char combustion chamber ( 2 ), for allowing the fluidizing medium heated in the char combustion chamber ( 2 ) to move from the char combustion chamber ( 2 ) via the first opening ( 25 ) into the gasification chamber ( 1 ).
