Exchanges heat with heated steam 35. Finally, the heated steam 36 that has also been discharged from the single bundle 4 of the downstream group 42 is sent out of the moisture separation heater 40 by the heated steam discharge pipe 26.
- the heated steam 36 in the U-shaped tube 2 of each tube bundle 4 is cooled to the heated steam 35 and condensed to generate condensed drain, but the condensed drain generated in each tube bundle 4 is transferred to each. Tsu It is sent to each drain pipe 10 attached to the dar 3 and collected together in the drain tank 101.
- the number of the tube bundles 4 through which the heated steam 36 is sent at one time is limited, and the condensed drain is sequentially discharged through the drain tube 10 in each of the tube bundles 4 of each dull, so that the U-shaped tube 2 of the tube bundle 4 is discharged.
- the flow rate of the heated steam 36 can be increased, and the force can also be prevented from filling the U-tube 2 of the tube bundle 4 with the condensed drain.
- the moisture separator / heater 40 of the present embodiment a part of the condensed drain sent from the header 3 of the tube bundle 4 to the drain tank 101 via the drain tube 10 is replaced with a drain feed tube.
- the high temperature region 31 may be cooled by being sent to the high temperature region 31 of the main body container 1 through 102.
- the temperature difference between the low temperature region 30 and the high temperature region 31 can be reduced, and the temperature distribution in the horizontal plane of the main body container 1 can be leveled.
