1. An organic material gasification system comprising:
a carbonization furnace to generate a carbide when an organic material is input to the carbonization furnace; and
a gasification furnace including a reactor having a cylindrical shape where the carbide generated by the carbonization furnace and a gasifying agent are input, and a heating unit to heat the reactor, to gasify the input carbide,
wherein the carbonization furnace includes an organic material combustion region where a part of the organic material is combusted above accumulated organic material to maintain a temperature of the carbonization furnace at a high temperature, a carbonization region provided below the organic material combustion region, where the organic material is carbonized, and a steam supply unit to supply high-temperature superheated steam of a temperature or higher exhibiting a high-temperature carbonization promotion effect, to the organic material in the organic material combustion region, and
the gasification furnace includes the heating unit having a tubular shape and penetrating through an inside of the reactor having a cylindrical shape in a longitudinal direction, and heats the reactor by causing high-temperature exhaust gas discharged from the carbonization furnace to pass through an inside of the heating unit having a tubular shape;
wherein the carbonization furnace includes a first air supply mechanism where a heating space in contact with an outer periphery of a first frame body portion is formed by the first frame body portion surrounding an outer side of the organic material combustion region forming a part of an outer frame body of the carbonization furnace, and having at least one through-hole, and by a first outer peripheral wall surrounding the outer periphery of the first frame body portion with a slight gap between the first outer peripheral wall and the first frame body portion, to supply air to the heating space, and to supply combustion air to the organic material combustion region from the through-hole.
