<p><P>PROBLEM TO BE SOLVED: To relax a limit on supply of steam for processing in comparison with a conventional case, by suppressing pressure fluctuation of a boiler in supplying the steam for processing from a main steam system of the boiler having a reheater to factory equipment. <P>SOLUTION: This steam supply system 5 including a steam supplying system 3 for supplying the steam for processing from boiler turbine power generating equipment 1 to the factory equipment 2, and a control device 4, further includes a reheated steam extraction pipe 60 connected to an upstream side of a low pressure turbine 16 at a downstream side of the reheater 27 in the reheated steam pipe 29, and a reheated steam extraction valve 61 disposed in the reheated steam extraction pipe 60. The steam supplying system 3 includes a steam extraction pipe 40 for extracting a part of the steam generated from the boiler 10, and a steam extraction valve 41. The control device 4 opens the reheated steam extraction valve 61 to supply the steam from the reheated steam pipe 29 to the factory equipment 2 when the steam is supplied to the factory equipment by opening the main steam extraction valve 41 and water is injected to the reheated steam pipe from a temperature decreasing device 28 by opening a water injection control valve 34. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
