Claims

[Scope of utility model registration request]

A nozzle member that changes the flow direction of solid particles is attached to the tip of a fuel supply pipe that pneumatically transports solid particles, and the solid particles are supplied into the fluidized bed by colliding with the nozzle member, in which the nozzle member is made of ceramics. A fluidized bed combustion apparatus characterized in that the collision wall of the nozzle member is provided with a protrusion.
