Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a metal fuel capable of causing strong combustion in various combustion devices for heat sources, propulsion power, and the like, and a metal fuel supply device used therefor. And can be used in an ion flame generator that ionizes a combustion flame (hydrocarbon flame) of kerosene or the like to generate an ion flame having a higher temperature than a combustion flame in a normal state (neutral flame).

[0002]

2. Description of the Related Art Conventionally, as an ion flame generator for generating an ion flame from a fuel such as kerosene, there has been an ion burner used in an incinerator. 12 and 13 show an example of an incinerator using this ion burner, which has the following structure.

In this incinerator, a neutral flame chamber D and a quasi-plasma (quasi-ion) flame chamber are vertically arranged inside a main body A of a castable refractory made of a tubular material through grate B and C. E, a plasma (ion) flame chamber F is formed, three kerosene burners G are attached to the furnace wall of the ion flame chamber F, and a flame contact ionizing material H is formed at the tip of the kerosene burner G in the ion flame chamber F. Things are arranged, and the electromagnetic coil I is arranged on the furnace wall surface of the portion of the kerosene burner G where the flame hits. The ion burner includes a kerosene burner G, a flame contact ionizer H, and an electromagnetic coil I. In this incinerator, a high-frequency magnetic field (for example, a magnetic flux density of 10,000 or more and a frequency of 20 to 50 M is applied by applying a pulse current or the like to the electromagnetic coil I.
When a high frequency magnetic field of about Hz is generated, the flame contact ionization material H is activated by the high frequency magnetic field, and an energy application action is brought to the flame contact ionization material H, and the kerosene burner that touches the flame contact ionization material H Combustion flame of G (hydrocarbon flame)
Is ionized (converted into plasma) and becomes an ion flame. This ion flame has a large number of ions in the ion flame chamber F, but in the quasi-ion chamber E the number of ions decreases and becomes a quasi-ion flame, and in the neutral flame chamber D it becomes a normal neutral flame. In this incinerator, when an object to be treated such as dust is put into the dust input port J, it is dried and burned in the neutral flame chamber D, and is gradually melted while falling in the quasi-ion flame chamber E and the ion flame chamber F. The melt is discharged from the discharge port K and discharged.

By the way, there is an ion flame state in which valence particles (carbon ions, hydrogen ions, oxygen ions, etc.) are present even in a hydrocarbon flame produced by normal combustion, but the number of generated ions is small, In the absence of a magnetic field, the ions immediately recombine to generate H2O, CO2, etc.,
It becomes a state of neutral flame. At the stage of transition from an ion flame to a neutral flame, a recombination reaction having an endothermic action occurs and heat is taken from the flame, so that the neutral flame has a reduced amount of energy as compared with the ion flame. For example, it is said that kerosene has an energy of about 8000K calories per liter, and the calorie released by the atomic dissociation reaction exceeds 10,000K calories, but in normal combustion, the ion flame state is extremely short-lived. Therefore, the high temperature could not be generated because the neutral flame was immediately transferred.

However, in the incinerator shown in FIGS. 12 and 13, a large number of ions can be generated by the aid of the flame contact ionizing material H to form an ion flame, and the generated ions can be recombined with each other by the high frequency magnetic field of the electromagnetic coil I. Therefore, the ion flame state can be maintained for a relatively long time, and the temperature inside the furnace can be set to 3000 ° C. or higher.

The flame contact ionizing material H used in the incinerator is produced by crystallizing a composition containing a photoactive substance and a magnetic material in an oxidizing atmosphere. The photoactive substance is a simple substance such as selenium, cadmium, titanium, lithium, barium, or thallium, or an oxide thereof, a sulfide, a compound such as a halide, and as a magnetic substance, a ferromagnetic substance (iron, nickel, Cobalt and its compounds, etc.) and paramagnetic materials (manganese, aluminum,
Tin and its compounds), diamagnetic materials (bismuth, phosphorus,
Copper, calcium, and their compounds).

[0007]

In the incinerator shown in FIGS. 12 and 13, an ion burner burns normal kerosene, heavy oil, etc. to generate an ion flame, but an ion flame that can be generated by a normal fuel such as kerosene, heavy oil, etc. There was a limit to the firepower.

An object of the present invention is to provide a method for producing a metal fuel capable of causing stronger combustion in various combustion devices, and a metal fuel supplier used for the method.

[0009]

As shown in FIG. 7, in the method for producing a metal fuel according to the first aspect of the present invention, the positive electrode 82 and the negative electrode 81 are opposed to each other in a liquid fuel such as kerosene or heavy oil. The positive electrode 82 and the negative electrode 81 are used for fuel, and the positive electrode 82 and the negative electrode 81 are used.
By generating an electric discharge between and, fine powder of fuel metal is generated and mixed in the liquid fuel.

As shown in FIG. 7, the metallic fuel supplier according to claim 2 of the present invention has a positive electrode 82 and a negative electrode 8 in an insulative fuel tank 80 for containing a liquid fuel such as kerosene or heavy oil.
1 and 2 are opposed to each other, and one or both of the electrodes 81 and 82 are used as a fuel metal so that a high voltage can be applied between the electrodes 81 and 82.

In the metallic fuel supply device according to the third aspect of the present invention, an electrode moving device 85 for moving either one or both of the positive electrode 82 and the negative electrode 81 to keep the distance between both electrodes constant. Be prepared.

In the incinerator, one incinerator body 1 is used.
It is also possible to provide the ion flame generator 2 only in the machine. FIG. 10 is an example thereof, in which electromagnetic coils (strong magnetic field / electric field generator) 100 are separately provided at the facing position and the left and right positions of the ion flame generating device 2. This electromagnetic coil 1
00 has the same structure as that of the ion breeder 4 shown in FIG. 4, and the cylindrical main body 60 has a ring 61 of a non-magnetic metal (brass, stainless steel, etc.) and a ferromagnetic metal (iron, nickel,
Rings 62 of cobalt or the like) are alternately connected to form a tubular shape, and an electromagnetic coil 63 is attached to the outer circumference of each ferromagnetic metal ring 62.

In the incinerator of FIG. 10, the positive ion flame injected into the incinerator body 1 is confined in a donut shape by the high frequency magnetic field generated by the ion breeder 4 and the high frequency magnetic field generated by the electromagnetic coil 100. . The heat-resistant pipe 3 provided in the incinerator body 1 can be arranged close to the ion flame generating device 2, but can also be arranged in the center of the furnace as shown by the phantom line in the figure.

The following effects can be obtained by using the metal fuel manufacturing method of the present invention and the metal fuel supplier used for the method. 1. It is possible to generate a strong ion flame containing metal ions that cannot be generated only by burning fossil fuels such as kerosene and heavy oil, and it is possible to raise the flame temperature to 4000 ° C. or higher. 2. If used in the combustion device of an incinerator, high temperature can be generated to increase the incineration capacity. 3. If it is used for an ion rocket engine, it can obtain a strong propulsive force. 4. A strong ion beam can be obtained when used in an ion processing device.
