    • An object of the present invention is to enhance heat exchange efficiency in a heat exchanger and to gasify a gasification feedstock efficiently. A gasification system (100) including a countercurrent type heat exchanger (30) configured to include a low-temperature side flow channel (36) through which a gasification feedstock flows, and a high-temperature side flow channel (37) to which treated water in a supercritical state is introduced, the treated water raising a temperature of the gasification feedstock, a gasification reactor (50) configured to gasify the gasification feedstock, whose temperature has been raised by the countercurrent type heat exchanger (30), by heating and pressurizing the gasification feedstock to be in a supercritical state, the gasification reactor (50) being configured to discharge the gasification feedstock as treated water in the supercritical state, and a treated water flow channel (55) configured to introduce, to the countercurrent type heat exchanger (30), the treated water that has been discharged from the gasification reactor (50), the gasification feedstock being introduced to the low-temperature side flow channel (36), the gasification system including an external heating means (35) configured to extract the introduced gasification feedstock from the middle of the low-temperature side flow channel (36), heat the extracted gasification feedstock, and return the heated gasification feedstock to a middle position on a feedstock downstream side of the extracted position.
