PROBLEM TO BE SOLVED: To provide a generating method of superheated steam which generates safely and economically the superheated steam of high temperature by inexpensive equipment having a simple structure, and the equipment therefor. SOLUTION: Water 11 is put in a closed vessel 13 and the vessel 13 is heated, while the pressure is reduced by a blowing means 14. The water 11 inside the vessel is boiled at a low temperature to generate steam. The steam thus generated is pressurized by the blowing means 14 and passed through a heater 15 so that the temperature thereof be raised, and thus the superheated steam is generated. The equipment 10 for generating the superheated steam has the vessel 13 provided with a heating source 12 changing the water 11 inside into the steam, the blowing means 14 connected to the vessel 13 to reduce the pressure inside to be lower than the atmospheric pressure and discharging the generated steam outside, and the heater 15 heating further the pressurized steam. |
