OVERHEATED WATER STEAM GENERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To prevent water of liquefied steam from entering an overheated steam generation part.SOLUTION: An overheated water steam generation device comprises: a steam generation part 2; an overheated steam generation part 3; a connection pipe 9 for introducing steam from the steam generation part 2 into the overheated steam generation part 3; and a reservoir part 8 which is provided for the connection pipe 9 to reserve liquefied water of the steam. The steam generation part 2 and overheated steam generation part 3 have cylindrical conductor heating elements 2T, 3T having internal flow passages formed inside; induction coils 2C, 3C provided inside or outside the conductor heating elements 2T, 3T; and magnetic path iron cores 101, 102 provided at center parts of the induction coils 2C, 3C. The magnetic path iron cores 101, 102 of the generation parts 2, 3 constitute a three-leg iron core together with a common iron core 103 serving as a common passage for magnetic flux generated at those two magnetic path iron cores 101, 102. The reservoir part 8 is arranged in the space surrounded with an outer face of the steam generation part 2, an outer face of the overheated steam generation part 3, and an outer face of the common iron core 103.SELECTED DRAWING: Figure 3
