Description

  The present invention relates to a combustion efficiency improving apparatus for improving the combustion efficiency of liquid fuel.

  Various combustion efficiency improvement apparatuses that improve the combustion efficiency by irradiating far-infrared rays to liquid fuel supplied to engines such as ships, buses, and trucks have been proposed. In this specification, electromagnetic waves having a wavelength capable of improving combustion efficiency, such as far infrared rays, are collectively referred to as “far infrared rays”.

  As the combustion efficiency improving device, a mixed dispersion in which at least tourmaline particles are dispersed in a conductive solution containing nanocarbon graphite particles is filled into a hollow member made of a conductive material whose surface is coated with hard anodized. In addition, there has been proposed one in which the periphery of a fuel pipe extending from a liquid fuel tank to a liquid fuel combustion device can be surrounded (see, for example, Patent Document 1).

  By the way, since C heavy oil used in ships and the like has a high viscosity, it is usually supplied to the engine through the fuel supply passage in a state where the viscosity is lowered by heating to 80 ° C. or 120 ° C.

Japanese Patent No. 4660191

  By the way, in the invention described in Patent Document 1, although the fuel efficiency can be improved by irradiating the far-infrared rays from the mixed dispersion liquid, for example, a mixture of water, tourmaline, and carbon particles is used as the mixed dispersion liquid. In this case, if the fuel temperature in the fuel supply path becomes high, the volume of water in the mixed dispersion increases or boils, so the C heavy oil used by heating to 80 ° C or 120 ° C is used. There was a problem that it could not be applied to ships that had been. Moreover, since it is necessary to mix nanocarbon graphite particles in order to impart conductivity to the mixed dispersion, there is also a problem that the manufacturing cost of the mixed dispersion increases.

  An object of the present invention is to provide a combustion efficiency improving device that can be used for a fuel having a low temperature of −45 ° C. to a high temperature of + 250 ° C. or higher, not to mention normal temperature.

  A combustion efficiency improving apparatus according to claim 1 is a combustion efficiency improving apparatus that irradiates far-infrared rays to fuel flowing in a fuel supply passage to improve combustion efficiency, and irradiates the fuel with far-infrared rays. As the substance to be used, a combustion improving material made of a mixture of a far infrared ray generating substance and an inert liquid whose electronic activity is activated by the far infrared ray is used. The combustion efficiency improving device is applicable not only to engines for ships, buses, trucks, but also to burners used in thermal power plants, incineration facilities, furnaces for casting and steel making, boilers, and the like. .

  In this combustion efficiency improving device, a combustion improving material made of a mixture of a far infrared ray generating substance and an inert liquid whose electronic activity is activated by the far infrared ray is used as a combustion improving material for irradiating the fuel with far infrared rays. Therefore, as the inert liquid, for example, a liquid whose volume does not change or boil even at a low temperature of −45 ° C. to a high temperature of +250 or more and whose electronic activity is activated by far infrared rays can be adopted. Even if the fuel in the fuel supply passage is heated to, for example, 80 ° C. or 120 ° C., such as a ship using C heavy oil, which has been considered difficult to apply, By irradiating far infrared rays, the combustion efficiency can be improved.

  Here, as the inert liquid, it is preferable to use a room temperature ionic liquid having heat resistance equal to or higher than the fuel temperature in the fuel supply passage. Use of a room temperature ionic liquid having such heat resistance is preferable because it can improve the combustion efficiency by applying the present invention to ships using C heavy oil heated to 80 ° C or 120 ° C. . As the room temperature ionic liquid, any chemical component can be used as long as it has heat resistance equal to or higher than the temperature of the fuel in the fuel supply passage.

  It is preferable to use graphite silica (Graphite Silica) powder, horn blended cumingtonite nepheline powder, or tourmaline powder as the far infrared ray generating substance. In particular, graphite silica is suitable because it can emit far-infrared rays even at room temperature.

  In a preferred embodiment, the mixing ratio of the inert liquid and the far infrared ray generating material is set to 1 to 75 wt% of the far infrared ray generating material with respect to 100 wt% of the inert liquid. When the mixing ratio of the far-infrared ray generating substance is less than 1 wt% with respect to 100 wt% of the inert liquid, the far-infrared ray cannot be sufficiently irradiated. When the mixing ratio exceeds 75 wt%, the fluidity of the mixture is low. The density of the far-infrared ray generating substance is reduced and the density of the far-infrared ray generating substance is reduced, and it becomes impossible to irradiate the edge infrared ray uniformly from the far-infrared ray emitting substance. In particular, the mixing ratio of the far infrared ray generating substance is preferably set to 5 to 50 wt%, and most preferably set to 10 to 25 wt%.

  Far-infrared radiation, comprising: the combustion improving material; a casing that accommodates the combustion improving material; and a helical coil portion that is embedded in the combustion improving material in the casing and circulates along the inner surface of the casing. It is also a preferred embodiment that includes a supply pipe made of a permeable material, and the supply pipe is interposed in the middle of the fuel supply passage. In this case, since the coil portion through which the fuel flows is embedded in the combustion improving material that irradiates far infrared rays, the far infrared rays can be efficiently applied to the fuel. Further, since the fuel is forcibly agitated in the coil portion, it becomes possible to uniformly irradiate far-infrared rays to the entire fuel. As a material that can transmit far infrared rays, an aluminum alloy can be preferably used.

  It is also a preferred embodiment that a cylindrical member is provided at the center of the casing, and a heating means is disposed in the cylindrical member. A heavy oil has a lower viscosity than C heavy oil and is not usually heated and is supplied to the engine or the like at room temperature. However, if a heating means is provided as in the present invention, the combustion improving material is heated. Therefore, the generation of far infrared rays from the combustion improving material is promoted, and the fuel can be sufficiently irradiated with far infrared rays, which is preferable.

  In a preferred embodiment, a reflecting plate made of a stainless steel plate having a mirror finish is provided on the inner peripheral surface or the outer peripheral surface of the casing surrounding the coil portion, with the mirror side facing inward. In this case, since the far infrared rays that are diffused to the outside can be reflected by the reflecting plate and applied to the coil portion, the far infrared rays can be more efficiently applied to the fuel.

  It is also a preferred embodiment to form fine irregularities on the inner peripheral surface and / or outer peripheral surface of the supply pipe. If comprised in this way, the surface area of a supply pipe | tube can be increased, the irradiation area of the far infrared rays with respect to a fuel can be increased, and a far infrared ray can be made to act still more efficiently with respect to a fuel. The fine unevenness can be formed by, for example, blasting or chemical treatment. In addition, if irregularities are formed on the inner peripheral surface of the supply pipe, turbulent flow is generated in the fuel flowing along the inner wall of the supply pipe, and the fuel flowing in the supply pipe is efficiently agitated. It becomes possible to irradiate far infrared rays more uniformly.

  It is also a preferred embodiment to provide the supply pipe with a spiral groove that protrudes inward continuously or intermittently. If comprised in this way, since the inside of a supply pipe | tube can be distribute | circulated, turning a fuel helically, it becomes possible to irradiate far-infrared rays more uniformly with respect to the whole fuel.

  In a preferred embodiment, the casing is sheathed with a heat insulating material. In this case, the temperature of the combustion improving material can be maintained without waste at a temperature at which far infrared rays can be efficiently emitted.

  The fuel is preferably C heavy oil. As mentioned above, since C heavy oil is usually used by heating to 80 ° C. or 120 ° C. because of its high viscosity, it was conventionally considered difficult to apply since the conductive liquid boils. The present invention can be applied by using an inert liquid.

  According to the combustion efficiency improving apparatus according to the present invention, as a combustion improving material for irradiating a fuel with a far infrared ray, a combustion comprising a mixture of a far infrared ray generating substance and an inert liquid whose electronic activity is activated by the far infrared ray. Since the improved material is used, as an inert liquid, for example, the volume does not change or boil from a low temperature of −45 ° C. to a high temperature of +250 or more, and electronic activity is activated by far infrared rays. Even if the fuel in the fuel supply passage is heated to, for example, 80 ° C. or 120 ° C., such as a ship using C heavy oil, which has been considered difficult to apply in the past, Combustion efficiency can be improved by irradiating the C heavy oil with far infrared rays.

As the heating means 15, a german heater can be suitably used, but other heating means can be employed. The heating means 15 heats the combustion improving material 11 and increases the far-infrared radiation amount when the fuel flowing through the fuel supply passage 3 is a fuel used at room temperature such as A heavy oil. belongs to. For this reason, when the fuel flowing through the fuel supply passage 3 is C heavy oil heated to 80 ° C. or 120 ° C., the heating means 15 can be omitted.

The inner case 17 and the outer case 18 penetrate through the inner case 17 and the outer case 18 in a liquid-tight manner and project outside. The coil portion 22 a of the supply pipe 22 is embedded in the combustion improving material 11 in the far infrared irradiation space 19. The supply pipe 22 is made of a material that can transmit far-infrared rays, such as an aluminum alloy, and the far-infrared radiation radiated from the combustion improving material 11 passes through the supply pipe 22 and flows through the supply pipe 22. Will be irradiated. Reference numeral 23 denotes a support bracket for fixing and supporting the supply pipe 22 to the inner case 17.

However, when the inflow end 22b of the supply pipe 22 is connected to the fuel supply passage 3 connected to the fuel tank 1, and the outflow end 22c of the supply pipe 22 is connected to the fuel supply passage 3 connected to the combustion device 2, the fuel supply When the combustion efficiency improving device 10 is installed in the passage 3, the fuel supply passage 3 connected to the fuel tank 1 is first connected to the inflow side end 22 b of the supply pipe 22, and the air in the supply pipe 22 is discharged. After the fuel is supplied and the air in the supply pipe 22 is completely discharged, the combustion supply path 3 connected to the combustion device 2 is connected to the outflow side end 22c of the supply pipe 22 so that the inside of the fuel supply path 3 The residual air at Preferable than that.

  It is also a preferred embodiment to form fine irregularities on the inner peripheral surface and / or outer peripheral surface of the supply pipe 22.

The fine unevenness can be formed by, for example, blasting or chemical treatment. In addition, when unevenness is formed on the inner peripheral surface of the supply pipe 22, turbulent flow is generated in the fuel flowing along the inner wall of the supply pipe, and the fuel flowing in the supply pipe 22 is efficiently stirred to On the other hand, it becomes possible to irradiate far infrared rays more uniformly. In addition, as shown in FIG. 4, it is also a preferred embodiment that a spiral groove 24 protruding inwardly in the supply pipe 22 is provided continuously or intermittently.

In addition, as the reflecting plate 25, it is also possible to employ a material other than the stainless steel plate. Moreover, although the reflecting plate 25 was provided along the inner peripheral surface of the trunk | drum member 17a, it is also possible to provide a mirror surface side inward along the outer peripheral surface of the trunk | drum member 17a.

Further, since the fuel is forcibly stirred in the coil portion 22a, it becomes possible to uniformly irradiate far-infrared rays with respect to the entire fuel. Furthermore, since the reflecting plate 25 is provided along the inner peripheral surface or the outer peripheral surface of the body member 17a, far infrared rays that are scattered to the outside can be reflected by the reflecting plate 25 and irradiated to the coil portion 22a.

In this case, the combustion improving material 11 is provided in the accommodating portion in the inner pipe. It is also possible to close the both ends and fill the gap between the inner tube and the outer tube as a fuel passage connected to the fuel supply passage 3.
