Is installed, the valve 10 is closed, and the condensate 9
Are accumulated along the vertical direction to form a liquid pool (not shown) in which the condensate flow path 8 is completely closed. When a predetermined amount of condensate is accumulated in the liquid pool, the valve 10 is opened.

すことによって行う。At this time, the vertical portion of the condensate flow path is filled with the condensate, and the condensate flow path is still completely closed. Therefore, backflow of the steam flow can be completely prevented. The condensate that has reached the horizontal part of the condensate flow path changes its direction to the horizontal direction and flows to the evaporator 2. The vapor flowing back in the horizontal portion is blocked by the condensate located in the vertical portion of the condensate flow path described above, and any further vapor backward flow is completely prevented. The valve 10 is closed before the condensate flow path is cleared. Control of opening / closing of the valve is performed by, for example, repeating opening / closing for a predetermined time in consideration of the pipe diameter, the shape of the pipe, and the like.
