[0037] By setting the partition plate 13, the interior of the steam conduction tube 3 can be divided into an upper chamber and a lower chamber. The upper chamber and the lower chamber are respectively connected by two steam conduction tubes 3 for steam conduction. High-pressure steam can be introduced into one chamber, and after being conducted by multiple heat transfer tubes 4, it is discharged from another chamber.
