Claims

[Scope of utility model registration request]

'Fluidized bed coal gas that is separated into a gasification section made of a fluidized bed and a combustion section made of a fluidized bed by a partition wall installed in a circular manner in the furnace, and particles are circulated between the gasification section and the combustion section. A fluidized bed coal characterized in that, in the oxidizing furnace, a constriction section is provided at the lower end of the moving bed section that connects the gasification section and the combustion section, and an aeration gas supply port is installed above the constriction section close to the constriction section. Gasifier.
