It becomes saturated water and flows into one side of the water storage tank from the inlet. The inflowing water passes through the electromagnetic filter, flows into the water storage tank on the other side, and is stored. At this time, the iron content contained in the water, that is, magnetite, etc., is adsorbed and removed by the filter part by the electromagnetic force of the electromagnetic filter, and therefore, on the other side of the water storage tank, that is, on the downstream side of the electromagnetic filter. Does not contain iron, so the water supplied from the water supply port does not contain iron.

If the differential pressure between the two sides of the electromagnetic filter becomes abnormally high, open the valve and guide the water through the conduit from one side of the water storage tank to the other side, that is, the downstream side of the electromagnetic filter.
Since water can be sent as water supply, the water supply to the steam generator will not be stopped.

Leading to the downstream side of the electromagnetic filter 13 by
Since water can be sent as the water supply 10, the water supply 10 to the steam generator 1 is not stopped even in such a case. In addition,
The valve 16 may be manually operated, or it will be more effective if the valve is automatically opened upon detection of an abnormal differential pressure.
