Property body metal formed heat treatment pipe 21 felt in the position of leading portion portion 21a, middle portion 21b, back segment portion 21c by the magnetic field
It answers and flows through eddy current.Moreover, in heat treatment pipe 21 eddy current that flows through due to heat treatment pipe 21 itself resistance and
Hot (that is, being inductively heated) is generated, the flying dust original powder in leading portion portion 21a, middle portion 21b, back segment portion 21c is carried out using the heat
Heating.Also, it is unburned carbon contained conductive comprising a few percent or so in flying dust original powder, therefore, leading portion portion 21a, in
Section portion 21b, back segment portion 21c carry out induction heating respectively.
The inside of heat treatment pipe 21 is maintained as the blocking of flying dust original powder and there's almost no the state of oxygen (air), changes
Yan Zhi, for there is no the state of the oxygen (air) of amount needed for unburned carbon contained (spontaneous combustion) on fire, furthermore, be oxygen
The state that (air) is hardly contacted with flying dust original powder is (only and in the gap that the particle of flying dust, unburned carbon contained etc. contacts with each other
The state of existing oxygen (air) contact).Therefore, it can prevent unburned carbon contained on fire (certainly in the inside of heat treatment pipe 21
Combustion) and temperature is caused to rise higher than imagining temperature.
Control device 25 obtains the measurement temperature data that temperature sensor TS1, TS2, TS3 are measured.Control device 25 will
Acquired each measurement temperature and each set temperature T1, T2, T3 of leading portion portion 21a, middle portion 21b, back segment portion 21c are compared
Compared with, for higher position, the signal for reducing output is sent to power supply 23a, 23b, 23c, on the contrary, for lower position, to
Power supply 23a, 23b, 23c send the signal for increase output.Power supply 23a, 23b, 23c of signal are received according to the reception of itself

Nearly set temperature T1, T2, T3 and consistently kept.
But although the unburned carbon contained content for including in flying dust original powder is a few percent or so, be not it is constant, deposit
In deviation and it is difficult to accurately grasp.Therefore, the unburned carbon contained calorific value based on induction heating contains according to unburned carbon contained
The difference of amount and change.The variation of the calorific value, which further becomes, makes leading portion portion 21a, middle portion 21b, back segment portion 21c
The reason of temperature changes.Therefore, in order to the temperature of leading portion portion 21a, middle portion 21b, back segment portion 21c are consistently remained
Set temperature T1, T2, T3, it is also possible to the case where appearance must be such that the output of above-mentioned power supply 23a, 23b, 23c significantly increases and decreases.But
It is that there are output area appropriate, the output more than the output area appropriate can apply power supply 23a by power supply 23a, 23b, 23c
Add excessive load, not preferably.Therefore, in addition to the output control of power supply 23a, 23b, 23c think that being also applied with makes to be supplied to
The unburned carbon contained amount that flying dust original powder per unit time in heat treatment pipe 21 is included becomes constant new control.That is,
Control device 25 is in a manner of making the temperature of back segment portion 21c consistently become set temperature T3, according to the survey of temperature sensor TS3
Amount temperature data, come the revolving speed increase and decrease for the electric motor 20g for having weight feed device 4.That is, control device 25 is to electronic
The revolving speed of motor 20g is controlled.
Here, power supply 23a, 23b, 23c are executed separately according to the measurement temperature data of temperature sensor TS1, TS2, TS3
Output control, also, electric motor is executed according to the measurement temperature data of the temperature sensor TS3 as most back segment
The control of the revolving speed of 20g.In such manner, it is possible to keep each control succinct, and can will be from the heat treatment pipe 21 of power heater 8
It (is in this embodiment, 600 that the temperature of flying dust original powder when supplying to carbon high-temp oxidation furnace 9, which reliably rises to target temperature,
℃)。
As described above, the execution of control device 25 is combined with electric motor 20g other than the control of the output of power supply 23c
Revolving speed control cascade Mach-Zehnder interferometer.Therefore, it can be realized unburned carbon contained subtle temperature adjustment.As a result, in back segment portion 21c
The temperature of flying dust original powder more precisely remained the set temperature T3 of back segment portion 21c.
In this way, the supply of oxygen and the almost shape of anaerobic is being not present in the flying dust original powder being supplied in heat treatment pipe 21
In the heat treatment pipe 21 of state it is mobile in a period of, flying dust original powder and it includes unburned carbon contained to be heat treatment pipe 21 interim
Ground heating, wherein the induction heating that the heat treatment pipe 21 passes through leading portion coil 22a, middle section coil 22b and back segment coil 22c
And it is periodically heated.Then, be heated to set temperature T3, be put to comprising unburned carbon contained flying dust original powder it is next
In the carbon high-temp oxidation furnace 9 of process.
In addition, in this embodiment, set temperature T3 is set to 600 DEG C, but it also can be set as pre- heat setting temperature
More than, wherein the pre- heat setting temperature is set to be higher than lower at least than unburned carbon contained temperature on fire (such as 600 DEG C)
200 DEG C of temperature (such as 400 DEG C).
In addition, in this embodiment, having used induction to be heated to the flying dust original powder in heat treatment pipe 21
