Abstract:
1. A fuel gasification equipment comprising: a gasification furnace with a fluidized bed of a bed material formed by a fluidizing reaction gas for gasifying a solid fuel charged to produce a gasification gas and a flammable solid content; a fluidizing reaction gas source connected to the gasification furnace; a downcomer provided at least partially in the gasification furnace arranged to supply a bed material from above the gasification furnace to an inner bottom of the fluidized bed; a fuel supply pipe connected to a side surface of said gasification furnace at a position lower than an upper surface of the fluidized bed for supplying a solid fuel into the fluidized bed; and confluence promoting means which allows the solid fuel supplied from the fuel supply pipe into the fluidized bed to join a flow of the bed material supplied from the downcomer to the inner bottom of the fluidized bed, said confluence promoting means being defined by a depth in said gasification furnace equal to an outer diameter of the downcomer and by a distance between the downcomer and the side surface of the gasification furnace connected to the fuel supply pipe at least equal to or less than an inner diameter of the fuel supply pipe.
