Claims

[Claims for Utility Model Registration] (1) A fluidized bed in which particles are held in a furnace, oxygen-containing gas is vented upward from the bottom of the furnace to form a fluidized bed, and fuel is combusted within the fluidized bed. In the furnace,
A fluidized bed furnace comprising an air supply device for supplying oxygen-containing gas near the bottom of metal members arranged in the furnace. (2) In a fluidized bed furnace, particles are held in the furnace and gas containing oxygen is vented upward from the bottom of the furnace to form a fluidized bed, and fuel is burned within the fluidized bed. A fluidized bed furnace characterized in that an air supply path for a gas containing oxygen is provided in a metal member, and an opening is provided in the metal member that is connected to the air supply path and blows out a gas containing oxygen in a downward direction. .
