Here it becomes non-condensable gas and condensate. In addition, steam supplied from other steam pipes passes through the cor/russa drive turbine stop valve 7, the gingresa drive turbine control valve 8t-, and drives the Fung V-tuna drive turbine 9. Then, the low pressure compressor 10 and the high pressure compressor 11 are driven by the driving force. The non-condensable gas in the condenser 5 is detected by pressure detection test 1
The condensate gas is sucked into a low-pressure compressor 10IC through a condensate gas extraction line 13 provided with 4 and is compressed. This compressed gas is cooled by an intercooler 12 and then compressed by a high pressure compressor 11.
