PROBLEM TO BE SOLVED: To efficiently discharge only residue oil in a high-temperature and high-pressure state, subsidiarily formed in a reformer while continuing hydrothermal reforming. SOLUTION: The method for reforming heavy oil by utilizing a hydrothermal reaction comprises a reforming step for subjecting a high-temperature and high-pressure water and the heavy oil to the hydrothermal reaction to produce a reformed oil, a reformed fuel-feeding step for feeding the produced reformed oil to a combustion chamber of a power plant, an extraction step for extracting the residue remaining in the reforming step and moving the extracted residue to a region having a temperature and pressure lower than those of the reforming step, a storing step for storing the extracted residue, a detecting step for detecting the liquid level of the residue and the pressure of the residue at the storing step, and a control step for controlling the timing of the start and the stop of the extracting step based on signals of the detected liquid level and pressure of the residue.
