PROBLEM TO BE SOLVED: To remove defects of a steam supplying system supplying high-pressure steam, by reducing pressure of supplied steam, while keeping the required temperature of the steam. SOLUTION: The steam supplying system comprises a low-pressure boiler 1 for generating low-pressure steam, and a steam-supplying route 2 for sending the low-pressure steam generated in the low-pressure boiler 1 to a steam using part. The system is provided with a high-pressure boiler 3 for generating high- pressure steam with higher pressure than the pressure of the steam generated in the low-pressure boiler 1 and a superheater 4 for superheating the low- pressure steam. A steam piping 12 for superheating connects the high-pressure boiler 3 with the superheater 4. Thus, the high-pressure steam generated in the high-pressure boiler 3 is supplied to the superheater 4 for superheating the low-pressure steam. The superheated low-pressure steam with high temperature is supplied to the steam using part. COPYRIGHT: (C)2004,JPO
