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, and the like, and a metal fuel supply device used for the method. For example, the present invention can be used in an ion flame generator that ionizes a combustion flame (hydrocarbon flame) such as kerosene to generate an ion flame having a higher temperature than a normal combustion flame (neutral flame).

[0002]

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

In this incinerator, a neutral flame chamber D and a quasi-plasma (quasi-ion) flame chamber are vertically arranged through a grate B and C inside an incinerator body A made of a castable refractory into a cylindrical shape. 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. An electromagnetic coil I is provided on the wall of the furnace where the flame of the kerosene burner G strikes. The ion burner includes a kerosene burner G, a flame contact ionizing material H, and an electromagnetic coil I. In this incinerator, a pulse current or the like is applied to the electromagnetic coil I to apply a high-frequency magnetic field (for example, a magnetic flux density of 10,000 or more and a frequency of 20 to 50 M).
When a high-frequency magnetic field of about Hz is generated, the flame contact ionizing material H is activated by the high frequency magnetic field, and an energy is applied to the flame contact ionizing material H. G combustion flame (hydrocarbon flame)
Is ionized (plasmaized) to become an ion flame. Although this ion flame has a large number of ions in the ion flame chamber F, the number of ions decreases in the quasi-ion chamber E to become 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 garbage is put into the garbage inlet J, it is dried and burned in the neutral flame chamber D, and is gradually melted while falling down in the quasi-ion flame chamber E and the ion flame chamber F. It is discharged as a melt from the discharge port K.

[0004] By the way, there is also an ion flame in which valence particles (carbon ions, hydrogen ions, oxygen ions, etc.) are present in a hydrocarbon flame by ordinary combustion, but the number of generated ions is small. In the absence of a magnetic field, the ions immediately recombine to produce 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 deprived from the flame, so that the neutral flame has a reduced energy amount as compared with the ion flame. For example, kerosene is said to have an energy of about 8000K calories per liter, and the calories released by the atomic dissociation reaction are said to exceed 10,000K calories, but in normal combustion, the ion flame state is very short-lived. However, the state immediately shifted to a neutral flame state, so that a high temperature could not be generated.

However, in the incinerator shown in FIGS. 12 and 13, an ion flame can be created by generating a large number of ions with the help of the flame contact ionizing material H, and the generated ions are recombined by the high frequency magnetic field of the electromagnetic coil I. Therefore, the state of the ion flame can be maintained for a relatively long time, and the furnace temperature can be increased to 3000 ° C. or more.

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

[0007]

In the incinerators shown in FIGS. 12 and 13, ion kerosene and heavy oil are burned by an ion burner to generate an ion flame, but an ion flame which can be generated by a normal fuel such as kerosene and heavy oil. Had limited firepower.

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

[0009]

As shown in FIG. 7, in the method for producing a metal fuel according to the present invention, a positive electrode 82 and a negative electrode 81 are opposed to each other in a liquid fuel such as kerosene or heavy oil. In addition, one or both of 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.
In this case, a fine powder of a metal for fuel is generated by causing a discharge between the fuel and the liquid, and mixed into the liquid fuel.

As shown in FIG. 7, the metal fuel supply device according to the second aspect of the present invention comprises a positive electrode 82 and a negative electrode 8 in an insulating fuel tank 80 for containing a liquid fuel such as kerosene or heavy oil.
1 is mounted so as to oppose, one or both of the electrodes 81 and 82 are made of a metal for fuel, and a high voltage can be applied between the electrodes 81 and 82.

According to a third aspect of the present invention, there is provided a metal fuel supply device which moves one or both of the positive electrode 82 and the negative electrode 81 to maintain a constant distance between the two electrodes. It is provided.

The electrode rod (positive electrode) 82 is attached. The negative electrode 81 is vertically and vertically fixed to the center of the bottom of the tank 80, and the two positive electrode rods 82 are
And a gland packing 84 is attached to the insertion portion so that the inserted plus electrode rod 82 can be freely inserted and removed, and a liquid leakage is prevented.

The gap between the discharge passage 81 and the discharge passage 81 is adjusted so that the discharge easily occurs. Automatic feeder 85
When the tip of the plus electrode rod 82 is reduced and shortened, only the shortened portion can be automatically sent to the minus electrode 81 side, and the distance between the electrodes can be kept constant at all times. Incidentally, the automatic feeder 85 controls the feed amount of the positive electrode rod 82 by, for example, measuring the distance between the electrodes from the outside of the tank 80 with an optical sensor, monitoring the potential or current between the electrodes, and performing appropriate discharge. It can be realized by various methods, such as making it occur, or determining beforehand the amount of reduction of the electrode rod due to discharge as the amount of reduction per unit time.

The negative electrode 81 and the positive electrode rod 82
Is connected to a high-voltage power supply 86, so that, for example, about 30000 to 100000 V can be applied between both electrodes. The applied voltage and current can be set as appropriate according to the shape of the negative electrode 81 and the positive electrode rod 82, the distance between the electrodes, and the electrode material.

The fuel tank 80 is also provided with a fuel amount monitoring device (not shown) for measuring the fuel amount in the tank. The negative electrode 81 and the positive electrode rod 82 in the tank 80 are exposed from the liquid level. It is made to be able to prevent that. This fuel amount monitoring device is, for example, for additionally supplying a predetermined amount of fuel when the amount decreases, or notifying the administrator. This fuel amount monitoring device prevents discharge from occurring when the electrodes are exposed from the liquid surface, and prevents the fuel tank 80 from firing or exploding by igniting kerosene as fuel.

An agitator 87 is provided above the fuel tank 80. The stirring device 87 includes a motor 88 and a propeller 89 driven and rotated by the motor 88, and the kerosene in the fuel tank 80 can be stirred by the propeller 89. The rotation speed of the propeller 89 can be set as appropriate.

The cracking device is for cracking heavy oil having a high boiling point to produce light oil having a low boiling point (such as gasoline). This cracking device is, for example, of a catalytic cracking type using a silica-alumina catalyst or a high temperature (800 to 800) without using a catalyst.
(850 ° C.). There is also a hydrocracking method in which nickel, tungsten or the like is supported on silica-alumina using high-pressure hydrogen. This cracking device is particularly effective when a fuel having a high boiling point such as heavy oil is used instead of kerosene.
