PROBLEM TO BE SOLVED: To provide a fluidized-bed furnace as a combined furnace consisting of a gasifying furnace and an oxidizing furnace formed in one unit. SOLUTION: The fluidized-bed furnace is partitioned into the gasifying furnace and the oxidizing furnace with a partition wall 8. The circulation flow of a fluid medium is formed in at least one of the gasifying furnace and the oxidizing furnace. The partition wall 8 has a communication port via which the fluid medium is distributed from the gasifying furnace to the oxidizing furnace or from the oxidizing furnace to the gasifying furnace.
