However, if it is used as fuel as it is, it emits CO ₂ into the atmosphere, causing global warming. For this reason, in the present embodiment, the carbonized material is refined, and utilization other than fuel is attempted.
The mixed gas is greatly different from other fossil fuels, and has a great feature that the inside of the pressure vessel 62 can be directly heated without requiring oxygen supply from the outside because the mixed gas itself contains oxygen necessary for combustion. is there.
