Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of the high-temperature steam utilization facility of the first embodiment. In FIG.
The water tank which can store water is shown.
In the high-temperature steam utilization facility of the first embodiment, the water supply tank 10
Is connected to one end of a pipe 50.
Is disposed inside the steam utilization chamber 40. The steam utilization chamber 40 will be described later in detail. In addition, the water supply tank 10 should just be able to store water, and various tanks can be used. Further, as the pipe 50, various pipes such as ceramics, steel pipe, stainless steel, and resin can be adopted.

The steam generator 20 is attached to the pipe 50 at a position lower than the water level inside the water supply tank 10. A steam heating device 30 is attached to the pipe 50 between the steam generator 20 and the steam utilization chamber 40 at a position higher than the water surface inside the water supply tank 10. The inside of the pipe 50 where the steam generator 20 is attached always contains water, and the pipe 50 where the steam heater 30 is attached does not contain water.

The steam generator 20 and the steam heating device 30 each use a heater as an electromagnetic induction heating type heater 21. FIG. 2 is a schematic sectional view of the heater 21 of the electromagnetic induction heating system. As shown in the figure, the heater 21 of the electromagnetic induction heating type is configured by a coil 22 wound around the outer periphery of a pipe 50 and a heating element 23 housed inside the pipe 50. The coil 22 to which an electric current is applied is formed by twisting litz wires, or by forming a copper tube such as a round tube, a half tube, and an elliptic tube into a coil shape. The heating element 23 generates heat by a magnetic field generated by passing an electric current through the coil 22, and has a structure in which water inside the pipe 50 can pass from one end to the other end. Further, the heat exchange efficiency between water passing through the inside of the pipe 50 and the heating element 23 varies depending on the shape of the heating element 23. For this reason, the shape of the heating element 23 is designed to increase the contact area with water and improve the heat exchange efficiency.
In addition, it is preferable that the shape be such that water can pass from one end to the other end, such as a honeycomb structure.
