[Claim 1]
An apparatus of manufacturing an ingot iron, comprising;
a drier for drying a carbon-containing material by using an exhaust gas :, discharged during a steelmaking process;
a gasifier generating a reducing gas by charging the dried carbon-
containing material through a conduit connected to the drier and then
combusting the carbon-containing material by a high temperature hot wind or
oxygen; and
lo an ingot iron furnace connected to the gasifier through the conduit and
allowing an iron ore or a reduced iron to be charged thereinto and allowing the reducing gas to be blown through a tuyere thereinto to manufacture the ingot iron.
ir> [Claim 2]
The apparatus of claim 1, further comprising:
a hot wind furnace for supplying the high temperature hot wind to the gasifier.
20 [Claim 3]
The apparatus of claim 1 or 2, further comprising: an exhaust gas supply apparatus for supplying the exhaust gas discharged from the ingot iron furnace to the gasifier.

[Claim 4]
The apparatus of claim 1, wherein:
the drier partially combusts the exhaust gas discharged during the steelmaking process to remove or reduce moisture or a volatile matter included in the carbon-containing material.
[Claim 5]
The apparatus of claim 1, wherein:
the ingot iron furnace is any one of a blast furnace, a FINEX melting gasifier, and a COREX melting gasifier.
[Claim 6]
The apparatus of claim 5, wherein:
in the case where the ingot iron furnace is the FINEX melting gasifier, the reducing gas generated in the gasifier is blown into the FINEX melting gasifier or a multi-stage fluidized-reduction furnace.
[Claim 7]
The apparatus of claim 5, wherein:
in the case where the ingot iron furnace is the COREX melting gasifier, the reducing gas generated in the gasifier is blown into the COREX melting gasifier or a shaft furnace.

[Claim 8]
The apparatus of claim 1, wherein:
a hydrogen (H2) content of the reducing gas is 30% or less.
[Claim 9]
The apparatus of claim 1, wherein:
a pressure of the gasifier is 5 bar or more and 20 bar or less.
[Claim 10]
The apparatus of claim 1, wherein:
a temperature of the reducing gas generated in the gasifier is 1,000°C or more.
[Claim 11]
The apparatus of claim 1, wherein:
the carbon-containing material is at least one selected from the group consisting of a coal, a pulverized coal, a thermal coal, a RDF, a RPF, and biomass.
[Claim 12]
A method of manufacturing an ingot iron, comprising:
drying a carbon-containing material by using an exhaust gas discharged

during a steelmaking process;
generating a reducing gas by charging the dried carbon-containing material into a gasifier and then combusting the carbon-containing material; and
charging an iron ore or a reduced iron into a furnace and blowing the reducing gas to perform reduction.
[Claim 13]
The method of claim 12, further comprising:
blowing the exhaust gas discharged after the iron ore or the reduced iron is reduced in the gasifier.
[Claim 14]
The method of claim 12 or 13, wherein:
in the drying of the carbon-containing material, the exhaust gas discharged during the steelmaking process is partially combusted to remove or reduce moisture or a volatile matter included in the carbon-containing material.
[Claim 15]
The method of claim 12, wherein:
the generating of the reducing gas is performed by blowing a high temperature hot wind or oxygen into the gasifier.
[Claim 16]

The method of claim 12, wherein:
the furnace is any one of a blast furnace, a FINEX melting gasifier, and a COREX melting gasifier.
[Claim 17]
The method of claim 12, wherein:
a hydrogen (H2) content of the reducing gas is 30% or less.
[Claim 18]
The method of claim 12, wherein:
a pressure of the gasifier is 5 bar or more and 20 bar or less.
[Claim 19]
The method of claim 12, wherein:
a temperature of the reducing gas generated in the gasifier is 1,000°C or more.
[Claim 20]
The method of claim 12, wherein:
the carbon-containing material is at least one selected from the group consisting of a coal, a pulverized coal, a thermal coal, a RDF, a RPF, and biomass.
