Claims

[Scope of utility model registration request]

In a fluidized bed gasifier that gasifies solid fuel by blowing oxygen-containing gas through a dispersion plate at the bottom of the fluidized bed to form a swirling flow along the direction of small holes in the dispersion plate. A partition wall is provided to divide the box into multiple concentric circles, and each wind box is individually connected to an inlet pipe for the above gas, and a gas with a low oxygen concentration or a gas that does not contain oxygen is introduced into the wind box near the center. A fluidized bed gasifier characterized by:
