FLASH STEAM GENERATOR
Document Type and Number:
Japanese Patent JP2018155421
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a flash steam generator capable of suppressing vibration of a drain pipe.SOLUTION: A flash steam generator 30 includes a flash tank 31 for re-evaporating recovered steam drain D1 and separating it into flash steam S3 and hot water W3, a bypass line L21 for making the steam drain D1 bypass the flash tank 31, can inside water level detection means 33 detecting a can inside water level of the flash tank 31, a can inside pressure detection means 34 detecting a can inside pressure, circulation passage switching means 32 composed of a plurality of control valves including a bypass valve disposed on the bypass line L21, and control means 37 controlling the circulation passage switching means 32. The control means 37 proportionally controls an opening of the bypass valve V36 within a range of a minimum set opening or more not causing full-close, on the basis of the detection pressure of the can inside pressure detection means 34, when the detection water level of the can inside water level detection means 33 is a lower limit water level LL or more.SELECTED DRAWING: Figure 1
