Title:
AUXILIARY BOILER EQUIPMENT FOR REACTOR POWER STATION
Document Type and Number:
Japanese Patent JP3871804
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reuse condensate generated in the stand-by side steam drum as supply water of a steam generation source for warming up, without discharging out of the system.
SOLUTION: An operation side stream drum 1 and a stand-by side steam drum 2 are connected with a steam main pipe 19, having a steam stop valve 18 and a pipe for warming up 25 having a depressurizing valve 26. To the steam main pipe 19, a steam supply pipe 20 is branch-connected, and to the steam supply pipe 20, a load using steam 20 is connected. The condensate outlet side of the load using steam 21 is connected to a condensate recovery equipment 23 via a condensate pipe 22. The condensate recovery equipment 23 is connected to a supply water tank 6 via a condensate flowout pipe 24, and the water supply tank 6 is connected to the operation side steam drum 1 and the stand-by side steam drum 2 via a water supply pump 5. To the condensate outlet pipe 12 of the two steam drums 1 and 2, a condensate flowout pipe 27 having the second electromagnetic valve 14b is branch-connected. To the condensate flowout pipe 27, a merging pipe 28 is connected, which is connected to the supply water tank 6. A second electromagnetic valve 14b is connected electrically to a level switch 16 which is attached to both the steam drums 1 and 2.
