PROBLEM TO BE SOLVED: To provide a gasifying furnace apparatus having such a structure that, an airtight structure between the outer peripheral surface of a casing of a burning material-supplying part in a burning material-supplying apparatus and the inner peripheral surface of a burning material-charging inlet port formed on the furnace wall of a fluidized bed gasifying furnace is protected from breakage due to the difference of thermal expansion, and the airtightness in the furnace can be kept. SOLUTION: The gasifying furnace apparatus comprises a gasifying furnace in which burning materials charged into the furnace are gasified and a burning material-supplying apparatus through which the burning materials are supplied into the gasifying furnace. A casing 14 of a burning material-supplying part of the burning material-supplying apparatus passes through a burning material- charging inlet formed on the furnace wall 15 of the gasifying furnace, and the front end opens at the inner surface of the furnace wall. In this structure, a clearance 26 is formed between the outer peripheral surface 14a of the casing of the burning material-supplying part and the inner surface 15a of the burning material-charging inlet, and a sealing member consisting of a gasket 21 and a ground packing 22 is placed in the clearance 26.
