Abstract: PURPOSE:To enable the number of level switches to be reduced and a space around a moisture separating and heating device to be effectively utilized by a method wherein drain flow passages for flowing drain separated by each of moisture separating devices are connected by a drain communication duct, a level sensing seat is fixed to the drain communication duct and then a drain water level is detected. CONSTITUTION:Drain flow passages 25 are connected by a drain communication duct 22 having a square shape. The upper part of the communication duct 22 is higher than a drain ceiling plate 27. A central partition plate 21 is provided with a steam drain hole 24. Under a normal operation, a slight liquid surface is left at a lower part of the drain communication duct 22. Under this condition, in the event that a drain tank 15 at one side may not perform any discharging operation, a liquid surface is generated in the drain communication duct 22. The drain is flowed to another normal drain tank 15. As the liquid surface exceeds the drain ceiling plate 27, steam having a volume corresponding to an increased liquid surface is released out of the steam drain hole 24. Water level in the drain communication duct 22 is accurately taken out through the level sensing seat 17. Accordingly, the moisture separating device 2 may accurately detect a water immersion level and thus it is possible to operate a level switch 18.
