To provide a pyrolysis gasifying apparatus affording a sufficient fuel residence time in a gasifying furnace and improving the cooling gas efficiency, C conversion rate and H conversion rate.
A steam feeding line 11 for feeding steam is connected to the base of the interior of the gasifying furnace 2 in order to fluidize a fuel and a bed material, form a fluidized bed 3' and gasify the fuel while producing char. A cylindrical combustion furnace 1 having the lower end opened and inserted deeply into the fluidized bed 3' and the top extending to the upper side of the gasifying furnace 2 is integrally installed in the gasifying furnace 2. An air feeding line 12 for feeding air to the lower end opening of the combustion furnace 1 is passed through and arranged in the base of the gasifying furnace 2 in order to lift and move the char in the combustion furnace 1, burn the char and generate heat necessary for gasification.
