PROBLEM TO BE SOLVED: To provide hydrothermal reaction equipment in which the operation cost is not much, the deposition of salts and the intrusion of a corrosive gas are prevented, and a pressure container can be formed out of an inexpensive material. SOLUTION: The hydrothermal reaction equipment 1 has a hydrothermal reactor 3, a gas-liquid separation system 5 for separating the reaction product of the hydrothermal reactor 3 into gas and liquid, and a system 7 for re-charging part of the gas (exhaust gas) separated by the system 5 into the hydrothermal reactor 3. An inner cylinder is formed with a clearance kept between it and the inner wall of the hydrothermal reactor 3, and the exhaust gas from an exhaust gas re-charging means 7 is passed through the clearance. The high pressure exhaust gas, after being somewhat compressed, is re-charged into the hydrothermal reactor to be used in various applications such as purging salts in the hydrothermal reactor and cooling, so that deposit and the corrosive gas can be discharged at low energy consumption, the pressure container can be constituted of an inexpensive material, and the economical properties of the hydrothermal reaction apparatus can be improved.
