Another side, apply positive and negative two polarity of alternating voltage in another polarity voltage (being in fig. 8 negative voltage).In addition,
The another side of another conductor tube layer 3b in two conductor tube layer 3a, 3b, applies in positive and negative two polarity of alternating voltage
The voltage (being in fig. 8 positive voltage) of one polarity, in another a conductor tube layer 3b side, applies alternating voltage positive and negative two
The voltage (being in fig. 8 negative voltage) of another polarity in individual polarity.That is, in a conductor tube layer 3a side and another
Conductor tube layer 3b another side applies the voltage of same polarity, is led in conductor tube layer 3a another side and at another
A body tube layer 3b side applies the voltage of same polarity.
That is, in the one end for stream socket 2Px conductor tube 2, constituting a side for constituting a conductor tube layer 3a
Or near it, it is connected to apply the binding post (not shown) of one polar voltages of alternating voltage from AC power 4,
Constitute conductor tube layer 3a stream socket 2Py conductor tube 2, constituting another side the other end or its near,
It is connected to apply the binding post (not shown) from another polar voltages of the alternating voltage of AC power 4.In addition, in structure
Into near another conductor tube layer 3b stream socket 2Py conductor tube 2, constituting another side the other end or its,
It is connected to apply the binding post (not shown) of one polar voltages of alternating voltage from AC power 4, it is another constituting
Individual conductor tube layer 3b it is conductor tube 2, constitute a side stream socket 2Px one end or its near, be connected to apply

By so applying alternating voltage, the electric current side flowed in each conductor tube layer 3a, 3b to each conductor tube layer 3a, 3b
To on the contrary, the magnetic flux that is produced when being powered to conductor tube layer 3a and the magnetic flux side produced when being powered to another conductor tube layer 3b
To on the contrary, cancelling out each other.
Fluid heating part 3 shown in Fig. 9 is by a conductor tube 2 using the alternating current circuit electrical connection comprising AC power 4
Constitute, the overall impedance value in fluid heating part 3 is divided into even number part, (is in the present embodiment 2 in the even number of formation
It is individual) cutting element 3a, 3b both ends, from AC power 4 apply alternating voltage.
Two cutting elements 3a, 3b are made up of inner conductor tube layer 3a and outer conductors tube layer 3b, the inner conductor pipe
A piece conductor tube 2 is wound spirality from a side to another side by layer 3a, and the outer conductors tube layer 3b is connected to described
The conductor tube layer 3a other end, the coiling direction identical side from another side to one end laterally with the inner conductor tube layer 3a
To winding spirality.The impedance value of these conductor tube layer 3a, 3b is of substantially equal.In the present embodiment, each conductor tube layer is made
3a, 3b number of windings etc. is identical.
So, circular concentric is connected into unidirectional mode of respective coiling direction, 2 layers of composition 2 is wound and leads
Body tube layer 3a, 3b.That is, the fluid heating part so constituted is continuously integrally formed two conductor tube layer 3a, 3b.In addition, leading
In the case that body tube layer is more than 4 even number, it is same direction to make coiling direction, and a conductor tube 2 is laterally another from one end
One side and then continuously it is wound into circular concentric from another side to a side.
In the fluid heating part 3 so constituted, the quantity with conductor tube layer is unrelated, two stream sockets 2Px, 2Py
Positioned at a side (being in fig .9 upper end side).
In the fluid heating part 3, in a side (being in fig .9 upper end side) for each conductor tube layer 3a, 3b, apply and hand over
The voltage (being in fig .9 positive voltage) of a polarity in positive and negative two polarity of voltage is flowed, in the other end of each conductor tube layer 3a, 3b
Side, connects the centre position between return portion, i.e. two stream socket of each conductor tube layer 3a, 3b, applies alternating current positive pressure
The voltage (being in fig .9 negative voltage) of another polarity in minus two polarity.So in the abutting end of two conductor tube layer 3a, 3b
Portion (position for being divided into cutting element) applies common voltage.
That is, end conductor tube 2, constituting stream socket 2Px of each conductor tube layer 3a, 3b is being constituted or its is attached
Closely, it is connected to apply the binding post (not shown) of one polar voltages of alternating voltage from AC power 4, it is each constituting

The binding post (not shown) of another polar voltages.In addition, the connection sheet 31 in Fig. 9 is arranged at return portion (centre position),
Connect the binding post of the AC power 4.
By so applying alternating voltage, the sense of current phase flowed in each conductor tube layer 3a, 3b to each conductor tube layer
Instead, the magnetic flux that is produced when being powered to conductor tube layer 3a and the flow direction phase produced when being powered to another conductor tube layer 3b
Instead, cancel out each other.
Fluid heating part 3 of the fluid heating part 3 relative to above-mentioned Fig. 7 shown in Figure 10, is used as leading for two cutting elements
The structure of body tube layer 3a, 3b is identical, but coiling direction, connection method and the side for applying alternating voltage of each conductor tube layer 3a, 3b
Method is different.

The heart is circular, and electrically connects into series system with AC power 4.Specifically, as shown in Figure 10, by each conductor tube layer
3a, 3b another side conductive member 5 connect and make its short circuit, constitute conductor tube layer 3a the other end and another
Individual conductor tube layer 3b the other end electrical connection.In addition, in the case of even number of the conductor tube layer for more than 4, because adjacent
Electrically connected between one side of conductor tube layer or between another side, and as series connection.
In the fluid heating part 3, in a side of two conductor tube layer 3a, 3b of series connection, i.e., in a conductor tube
A layer 3a side, applies the voltage (being in Fig. 10 positive voltage) of a polarity in positive and negative two polarity of alternating voltage, in string
The another side of two conductor tube layer 3a, 3b of connection, i.e. a side in another conductor tube layer 3b, apply alternating voltage positive and negative
The voltage (being in Fig. 10 negative voltage) of another polarity in two polarity.
That is, constitute conductor tube layer 3a stream socket 2Px conductor tube 2, constituting side end or
Near it, it is connected to apply the binding post (not shown) of one polar voltages of alternating voltage from AC power, in structure
Into near another conductor tube layer 3b stream socket 2Px conductor tube 2, constituting side end or its, connection is used
In the binding post (not shown) for applying alternating voltage another polar voltages from AC power.
By so applying alternating voltage, the electric current side flowed in each conductor tube layer 3a, 3b to each conductor tube layer 3a, 3b
To on the contrary, the magnetic flux that is produced when being powered to conductor tube layer and the flow direction phase produced when being powered to another conductor tube layer
Instead, cancel out each other.

Position (boundary position of two cutting elements) applies the voltage (examination of another polarity in positive and negative two polarity of single-phase AC voltage
Test No.2, Figure 17 (2)).
Now, as shown in table 8, in the case where testing No.1, power factor is 0.1715, and in experiment No.2 situation
Under, in the case of with experiment No.1 equal-wattages, power factor is 0.1985.It so can consider the situation in Figure 17 (2)
Under, because the magnetic flux produced in two cutting elements is cancelled out each other, it is possible to suppress voltage reduction, improve power factor.
Moreover, 1~table of table 3 is the table for representing to be adapted to the example using fluid heater.As shown in Table 1 to Table 3, can be with
Superheated steam produced with the fluid heater 100 of present embodiment etc. is used for various suitable examples (purposes).I.e., it is possible to
The fluid heater 100 of present embodiment is assembled into equipment corresponding with the suitable examples shown in 1~table of table 3 to use.
In addition, the invention is not restricted to the embodiment, it can carry out without departing from the spirit and scope of the present invention
