PROBLEM TO BE SOLVED: To provide a pressurized heating apparatus which is capable of surely preventing the occurrence of a cold spot within a pressure vessel without using excessive vapor and shortening the required time considered necessary for pressurized heating. SOLUTION: A circulating pipe 10 for communicating an upper side aperture 8 disposed in the upper part of the pressure vessel 2 and a lower side aperture 9 disposed in the lower part of the pressure vessel 2 is disposed on the outer side of the pressure vessel 2 and the route of the circulating pipe 10 is provided thereon with a turbo blower 11 and a vapor supply pipe 12 is connected thereto, by which the air in the pressure vessel 2 and the vapor supplied to the circulating pipe 10 are powerfully stirred and a temperature distribution and vapor density are made uniform. |
