Problems solved by technology

[0004] However, the electrical connection member or soldered portion as the junction becomes high in temperature due to concentrated short-circuit current, and stress is generated due to deformation caused by thermal expansion of the winding portion of the conductor tube, thereby causing a problem of damage to the junction and the conductor tube.

Embodiment Construction

[0033] Hereinafter, one embodiment of the superheated steam generation device 100 of the present invention will be described with reference to the drawings.

[0034] Such as figure 1 As shown, the superheated steam generating device 100 generates superheated steam over 100°C (200°C-2000°C) by heating water or steam, and the superheated steam generating device 100 has a spirally wound circle A tubular conductor tube 2 and a magnetic flux generating mechanism 3 for inductively heating the conductor tube 2 .

[0035] The conductor pipe 2 is formed of a metal pipe, has a helically wound winding portion 2x, and is formed at one end of the conductor pipe 2 with an inlet P1 for introducing water or steam, and at the other end with a The export port P2 which leads out the generated superheated steam. An external pipe for supplying water or steam to the conductor pipe 2 is connected to the inlet P1, and an external pipe for supplying the generated superheated steam to the use side (f...

Abstract

The present invention provides a superheated steam generating device and a method for manufacturing a conductor tube used in the device. By forming a short circuit in the conductor tube, the reactance can be reduced, and the possibility of damage to the junction part and the conductor tube can be reduced. The superheated steam generating device induction-heats the helically wound circular tubular conductor tube through a magnetic flux generating mechanism provided inside or outside the winding portion of the conductor tube, and heats the water flowing through the conductor tube. The steam generates superheated steam, and substantially the entire winding portion of the conductor tube, the opposing surfaces of the adjacent adjacent parts are joined by the joint part, and the thickness of the joint part is equal to or greater than the tube thickness of the conductor tube.

Description

technical field [0001] The present invention relates to a superheated steam generator for generating superheated steam by inductively heating a helically wound conductive tube to heat water vapor flowing in the conductive tube. Background technique [0002] Conventionally, in such a fluid heating device, as disclosed in Patent Document 1, there is a method in which, among the helically wound conductor tubes forming the secondary coil, the conductor tubes adjacent to each other in the wound portion are short-circuited to form a short-circuit circuit. , thereby reducing the reactance to increase the heating efficiency of the fluid heating device has been known to the public. [0003] Here, the electrical connection member extending in the axial direction of the spiral is connected to a part of the circumference of the winding portion by welding or the like, or by locally welding and joining conductor tubes adjacent to each other in the winding portion, thereby constituting the...
