<P>PROBLEM TO BE SOLVED: To provide blow fluid treatment equipment in an ejector main steam system, which is practical and easily applicable to an existing steam power generation plant with a simple modification, and which can reduce the running cost. <P>SOLUTION: The steam power generation plant includes a starting bypass device and an ejector main steam system 40 for supplying main steam of a boiler 1 as working steam to an ejector 33 that sucks and removes non-condensing gas in a condenser 21, wherein the plant is provided with a recovering system for introducing a drain and/or steam exhausted from the ejector main steam system 40 on starting, into a condensing and recovering device. The drain and/or steam exhausted from the ejector main steam system 40 on starting the steam power generation plant is introduced to a desuperheater 55 of the starting bypass device, in which the temperature of the drain and/or steam together with excessive steam exhausted from a flash tank 53 and/or steam exhausted from a turbine bypass system 54 is adjusted in the desuperheater 55; and then the drain and/or steam is supplied to the condenser 21 to be condensed into water. <P>COPYRIGHT: (C)2012,JPO&INPIT |
