Patent ID: 8480766

Claim:
Gasification equipment, comprising: CO 2 charging means for charging CO 2 from an outside into a gasification furnace for producing a gasification gas by a reaction between a carbonaceous fuel and O 2 , wherein, the CO 2 charging means is i) a fuel transport means for transporting the carbonaceous fuel into the gasification furnace, and ii) a cooling means for charging CO 2 for cooling at an outlet of the gasification furnace, and the CO 2 charging means structured and arranged to adjust so that the CO 2 is charged into the gasification furnace at a first location together with the carbonaceous fuel transported by the fuel transport means, whereby an endothermic reaction for producing the gasification gas is accelerated, and is charged at a second location in an amount of CO 2 adjusted in accordance with a status of operation of the gasification furnace to control cooling from the endothermic reaction of the charged CO 2 .
