Background Art

[0002] Conventionally, by adding a surfactant and water to the fuel of an internal combustion engine and burning it, the combustion temperature decreases, but the expansion pressure is maintained by the vapor pressure of the mixed water. It is known that by reducing the exhaust gas temperature and converting that part into kinetic energy, fuel can be saved, thereby reducing fuel consumption and carbon emissions.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Patent Document 1 discloses an invention for burning combustible dust in factory exhaust gas. Also, Patent Document 2 discloses an invention in which carbon dioxide generated in coal power generation is used for culturing algae that produce oil, oil is extracted from the algae, and the squeezed residue and moisture of the algae are added to coal and burned in a boiler to appropriately lower the combustion temperature. Note that coal processed into pulverized coal used in coal power generation has a particle size of 10 μm to 500 μm, and it is known that soot (i.e., combustible dust) is generated due to incomplete combustion during power generation. Marine microorganisms and aquatic microorganisms have a large variation in size, and it is not easy to perform selective culturing.

[0005] On the other hand, emulsion fuels, which are mixtures of water and liquid fuel, have issues with ignition and combustion continuity due to the lower combustion temperature caused by the inclusion of water. Furthermore, in internal combustion engines that use gaseous fuels, the combustion state is easily affected by the amount of water. Furthermore, with solid fuels, sufficient ignition may not be achieved depending on the average particle shape of the solid fuel. The object of the present invention is to improve the ignition and combustion continuity of emulsion fuels, solid fuels, or gaseous fuels. [Means for solving the problem]

[0006] In order to solve the above problem, one embodiment of the present invention provides an ignition improver that is mixed with liquid fuel or solid fuel, and is characterized by containing soil bacteria having a dry diameter of 0.1 to 100 μm or water containing the corpses of the soil bacteria.

[0007] The ignition improver contains water and soil bacteria or dead soil bacteria with a dry diameter of 0.1 to 100 μm. The soil bacteria or dead soil bacteria function as combustible dust, promoting the ignition of emulsion fuel or solid fuel. The soil bacteria have a cell membrane with a phospholipid bilayer structure and are surfactants that allow them to disperse in both polar substances such as water and non-polar substances such as liquid fuel. The soil bacteria are composed of carbohydrates, lipids, proteins, and trace minerals, with the majority of their composition being organic matter, which is a combustible component. In a high-temperature, dry combustion chamber, the organic matter contained in the ignition improver generates combustible gas from its surface. Furthermore, the surfactant properties of the cell membrane prevent the soil bacteria from settling in the emulsion fuel, resulting in an ignition improver with excellent ignition and combustion continuity due to the combustible gas generated from the organic matter.

[0008] In order to solve the above problem, one embodiment of the present invention provides an ignition improver that is mixed with gaseous fuel, and is characterized in that soil bacteria having a dry diameter of 0.1 to 100 μm or water containing the corpses of the soil bacteria is sprayed and mixed with the gaseous fuel.

[0009] By spraying water containing soil bacteria with a dry diameter of 0.1 to 100 μm or the remains of the soil bacteria, it can be mixed with gaseous fuel. Furthermore, for example, the spraying amount of the soil bacteria water can be adjusted according to the combustion state of the internal combustion engine. As a result, since the combustion state of the internal combustion engine is stabilized when water is added, an effective combustion state can be provided.

[0010] In order to solve the above problems, the ignition improver of the present invention can be characterized in that it is for an internal combustion engine supplied to the combustion chamber of the internal combustion engine.

[0011] Using emulsion fuel in an internal combustion engine poses a problem of a decrease in combustion temperature due to the heat of vaporization. In particular, in the mixing ratio of fuel and water of the emulsion fuel, as the mixing ratio of water increases, the heat of vaporization increases, so the influence of the decrease in combustion temperature becomes greater. Also, when solid fuel is used in an internal combustion engine, ignition due to water addition becomes a problem. According to the ignition improver of the present invention, even when the mixing ratio of water is large in the mixing ratio of fuel and water of the emulsion fuel, ignition occurs, and in the case of pulverized solid fuel, combustion stabilization is achieved by assisting the combustion of the pulverized fuel by the effect of combustible gas generated in the process of dust combustion of bacteria, and the energy efficiency of the internal combustion engine is improved by the increase in water vapor due to water addition.

[0012] In order to solve the above problems, the ignition improver of the present invention can be characterized in that it is mixed with gaseous fuel by a spraying device and supplied to the combustion chamber of the internal combustion engine.

[0013] By spraying and mixing soil bacteria water into the intake air, a spraying nozzle for spraying soil bacteria water is required, but since the emulsion generation process is not required, the addition of a surfactant is not required. Also, since it is added by a spraying nozzle, it is possible to adjust the spraying amount according to the combustion state and always ensure stable combustion, which is advantageous for combustion engines with large output variations such as automobile engines.

[0014] To solve the above problems, a method for manufacturing an ignition improver according to an embodiment of the present invention includes a culturing step of culturing soil bacteria water in which soil bacteria, an additive, and water are mixed, a filtering step of filtering the soil bacteria water that has undergone the culturing step, and a sterilizing step of sterilizing the soil bacteria water that has undergone the filtering step, and is characterized by an ignition improver that is mixed with liquid fuel, solid fuel, and gaseous fuel.

[0015] By having a culturing step of culturing soil bacteria suitable for combustion assistance, a filtering step of making the particle size of the soil bacteria suitable for combustion assistance uniform and improving the combustion assistance property by removing impurities in the soil bacteria water, and a sterilizing step of immobilizing the soil bacteria water at a bacterial density suitable for combustion assistance, an ignition improver suitable for combustion assistance of liquid fuel, solid fuel, and gaseous fuel can be provided.

[0016] To solve the above problems, a method for manufacturing an ignition improver according to an embodiment of the present invention can be a method for manufacturing an ignition improver, characterized in that the mixed water is sterilized at 55 to 70 °C in the sterilizing step.

[0017] By the above manufacturing method, it is possible to further sterilize in a bacterial environment more suitable for combustion, so it is possible to provide an ignition improver more suitable for combustion assistance of liquid fuel, solid fuel, and gaseous fuel.

Effects of the Invention

[0018] According to the ignition improver of the present invention, in emulsion fuel, solid fuel, and gaseous fuel, even if water is added due to the combustion assistance effect of dust combustion of bacteria, the ignitability and combustion continuity can be improved, the water vapor can be increased, and the combustion temperature can be lowered to improve the combustion efficiency and achieve energy savings.

[Figure 4] FIG. 1 is an explanatory diagram showing the culturing step in the method for producing an ignition improver of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] This article describes water containing soil bacteria with a dry diameter of 0.1 to 100 μm or the corpses of such soil bacteria (hereinafter referred to as "soil bacteria water"). Unless otherwise specified, percentages in this specification are by mass. The solid:liquid mixture ratio is a mass ratio, and the liquid:liquid mixture ratio is a volume ratio.

[0021] If the dust particle size in the combustion chamber is too large, it takes too long for the dust to burn completely, preventing it from being completely combusted. During a dust explosion, flammable gases are generated from the dust surface and ignite due to ignition factors such as high temperatures. However, if the particle size is large, the surface area relative to the powder weight is small, which dilutes the concentration of the generated flammable gas and prevents it from igniting. Furthermore, if the dust particle size in the combustion chamber is too large, problems occur, such as settling during mixing and clogging of the nozzle. Furthermore, if the dust particle size in the combustion chamber is too small, oxidation in the air progresses, suppressing the generation of flammable gases and making handling difficult during storage and manufacturing. The explosion range of a dust explosion is known to be between 0.1 and 100 μm in dust particle size.

[0022] The soil bacteria referred to in the present invention are not particularly limited as long as they are soil bacteria contained in soil, but preferred soil bacteria in this embodiment include bacteria such as actinomycetes, Bacillus, and species of the genus Clostridium, which are obligate anaerobic bacteria, for example, Bacillus subtilis (Bacillus subtilis), Bacillus cereus, Bacillus penetrans, Bacillus licheniformis, Clostridium botulinum, Clostridium butyricum, Clostridium thermocellum, and Bacillus megaterium. fungi such as Trichoderma megaterium, Trichoderma genus, and rhizobia; yeasts such as Trichoderma hamatum, Trichoderma harzianam, Trichoderma polysporum, Trichoderma konigii, Trichoderma viride, and Saccharomyces cerevisiae; facultative anaerobic bacteria such as Staphylococcus genus, Corynebacterium genus, and Escherichia genus of Escherichia coli; and mixtures thereof. Particularly preferred are facultative anaerobes, obligate anaerobic bacteria of the genus Clostridium, such as Clostridium botulinum, Clostridium butyricum, and Clostridium thermocellum, and mixtures thereof.

[0023] Soil bacteria, unlike aquatic microorganisms such as cyanobacteria, include the diverse intestinal microorganisms of many animals, have a wide range of culture nutrition options and can be easily cultured, and it is easy to make the number of bacteria and the size of the bacteria uniform under culture conditions. For example, the observed Clostridium butyricum is 0.5 - 0.7 × 1.5 - 1.9 × 14 - 16 μm, and for soil bacteria, there is a high probability of being included within the range of 0.1 - 100 μm. On the other hand, some Microcystis, which is a cyanobacterium, has a particle size exceeding 100 μm, and those forming colonies and having an even larger diameter were also confirmed. Also, depending on the culture conditions, cyanobacteria may proliferate massively and there is a possibility of forming algal blooms, so it is difficult to control the number of bacteria. The components of soil bacteria are carbohydrates, lipids, proteins, and trace amounts of minerals, and are almost all combustible components. In the high-temperature and dry internal combustion chamber, combustible gas is generated from the surface of the soil bacteria and ignites in the flame inside the internal combustion chamber. This causes other soil bacteria to catch fire as well. Even in an environment where there is a large amount of water in the internal combustion chamber and the combustion temperature decreases and the combustion state is likely to change, combustion can continue.

[0024] By putting water into the combustion chamber of an internal combustion engine, the amount of water vapor generated increases and the exhaust gas temperature decreases. Since the amount of water vapor increases, even if the amount of fuel input is reduced by that amount, the amount of work done externally does not change. As a result, it becomes possible to reduce fuel by the amount by which the exhaust gas temperature is lowered. However, when adding water during combustion, the combustion state tends to change easily, such as becoming unstable or misfiring. As the proportion of water vapor in the gas during combustion increases, the combustible gas is diluted by the water vapor and the combustion state changes significantly.

[0025] By supplying soil bacteria water to the combustion chamber of an internal combustion engine, soil bacteria containing water will be scattered in the combustion chamber of the internal combustion engine as dust, but it takes time for the moisture to evaporate and for the soil bacteria to release combustible gas. As a result, ignition occurs slightly delayed from the ignition timing of the internal combustion engine, so in the case of an engine, it ignites near top dead center, and in the case of a turbine, it ignites near the maximum compression point, thus stabilizing the combustion state in the combustion chamber of the internal combustion engine.

[0026] The liquid fuel used in the present invention is not particularly limited and is generally used in internal combustion engines, and examples thereof include gasoline, diesel, kerosene, heavy oil, alcohol, liquefied fuels obtained by liquefying coal, vegetable oils, and fatty acids extracted from animal oils.

[0027] The solid fuel used in the present invention is not particularly limited and may be any fuel generally used in boilers for power generation, etc. Specific examples include coal, charcoal, coke, solid alcohol, and combustible biomass such as wood.

[0028] The additives used in the present invention are those that are necessary for the cultivation of soil bacteria, and include nitrogen, protein, carbohydrates, vitamins, mineral components, and the like.

[0029] The emulsion fuel used in the present invention may contain an emulsifier. Commonly used emulsifiers include anionic surfactants, nonionic surfactants, cationic surfactants, and amphoteric surfactants. Anionic surfactants include sodium fatty acid salts, potassium fatty acid salts, alpha-sulfo fatty acid methyl ester salts, sodium linear alkylbenzene sulfonate, sodium alkyl sulfate esters, sodium alkyl ether sulfate esters, sodium alpha-olefin sulfonate, and sodium alkyl sulfonates. Nonionic surfactants include sucrose fatty acid esters, sorbitan fatty acid esters, polyoxyethylene sorbitan fatty acid esters, fatty acid alkanolamides, polyoxyethylene alkyl ethers, and polyoxyethylene alkyl phenyl ethers. Cationic surfactants include alkyltrimethylammonium salts and dialkyldimethylammonium salts. Amphoteric surfactants include sodium alkylamino fatty acids, alkyl betaines, and alkylamine oxides.

[0030] For example, the emulsifier can be added in an amount of preferably 0.1 to 3%, more preferably 1 to 1.5%, based on the total weight of fuel oil and water. It has been confirmed that the emulsifier not only mixes the liquid fuel and water, but also inhibits water solidification at low temperatures and has an anti-rust and anti-corrosion effect on metals inside piping when emulsion fuel is used.

[0031] However, when soil bacteria water is made into mist and mixed with gaseous fuel as described in Example 3 below, the emulsifier is not necessarily required.

[0032] The mixing ratio of soil bacteria water to liquid fuel is preferably within the range of 10:1 to 1:1, and more preferably within the range of 8:1 to 1:1. If the ratio of soil bacteria water exceeds this range, the amount of water entering the combustion chamber increases, which tends to make ignition in the combustion chamber of the internal combustion engine difficult, and if the ratio of liquid fuel exceeds this range, the exhaust gas temperature increases, which increases the amount of energy wasted, reducing the energy saving effect of the internal combustion engine.

[0033] By burning soil bacteria water with fuel in the combustion chamber, the heat generated by the soil bacteria combustion replenishes the heat needed to continue combustion, making up for the drop in combustion temperature caused by the addition of water. This stabilizes combustion and allows more water to be supplied to the combustion chamber. This generates water vapor, which lowers the exhaust gas temperature, thereby improving the energy conversion efficiency of the combustion chamber in internal combustion engines. Furthermore, in boilers, adding water to the combustion chamber lowers the combustion temperature and exhaust gas temperature. Compared to high temperatures, the amount of short-wavelength infrared radiation from the boiler walls, which corresponds to the atmospheric window, is reduced, and the increased water vapor in the exhaust increases the amount of mid- and long-wavelength infrared radiation, which has a high greenhouse effect. This improves thermal efficiency, thereby reducing the amount of fuel consumed and carbon emissions.

[0034] The emulsions shown in Table 2 below were burned in a kerosene boiler and the state of combustion was observed.

[0035] [Preparation method of soil bacteria water] To prepare soil bacteria water, a solution containing additives such as minerals and organic matter is added to fresh water at an ambient temperature of approximately 30°C in summer and hot water in winter. The nutrient solution is then incubated at 25-35°C, with a carrier containing soil bacteria held in sawdust, for 1-2 weeks. Once saturated with bacteria, the supernatant is collected and filtered through coarse filter paper to obtain pure water. This is then sterilized at low temperature for 30 minutes at 63°C to obtain soil bacteria water. Diluted soil bacteria water is prepared by diluting soil bacteria water 50 times by volume and adding a surfactant to make the concentration 1% by volume. The "water" in Table 2 simply refers to water to which a surfactant has been added to make the concentration 1% by volume.

[0036] The soil bacteria water was prepared so that the ratio of soil bacteria carrier weight to additives to water was 0.5:19.5:80. The soil bacteria carrier:water ratio is preferably in the range of 1:70-200, and more preferably in the range of 1:80-100. A water ratio of less than 70 is unsuitable for the growth of soil bacteria. A water ratio of more than 200 tends to make it difficult to obtain the effect of dust combustion.

[0037] Soil bacteria carriers, specifically sawdust, are carriers onto which bacteria are soaked in cultured soil bacteria water and then dried. Immediately after cultivation, the soil bacteria water is cloudy and odorous. However, as cultivation progresses, the added nutrients of the bacterial culture, which are organic components other than the bacteria, are consumed, reducing the odor and increasing the liquid's transparency. Figure 3 shows the liquid immediately after cultivation, and Figure 4 shows the liquid at the time of use. Typically, impure organic matter other than dead soil bacteria is removed within 1-2 weeks, making the liquid ready for use as soil bacteria water. Filtration is performed using a 100 μm mesh water treatment filter to filter out bacteria with a wet diameter of 100 μm or larger, reducing the dry diameter of the bacteria that pass through the filter to 50 μm or less.

[0038] By sterilization, the composition and quantity of bacterial species are fixed. Since the protein constituting the bacteria is liable to undergo thermal denaturation in the high-temperature range, it is preferable to sterilize under conditions that can suppress protein denaturation, oxidation, and shape change. Specifically, the water temperature of the object to be sterilized is preferably 50°C to 100°C, more preferably 55°C to 70°C. Furthermore, under the said temperature conditions, it is preferable that the sterilization time be adjusted. For example, when sterilizing at 55°C to 70°C, it is preferable to adopt the sterilization time shown in Table 1. In addition to, or instead of, the above heat sterilization, high-pressure sterilization, retort sterilization, etc. may also be carried out. After the sterilization time has elapsed, the periphery of the container is quickly cooled with cold water to lower the water temperature to near room temperature. When the temperature becomes high, due to the denaturation of the protein contained in the soil bacteria, discoloration (such as browning) due to oxidation, change in the bacterial size due to the change in the three-dimensional structure of the protein, denaturation, etc. occur. Also, in the case of low temperature, sterilization may not be sufficiently carried out. In such cases, sufficient effects may not be obtained in the mixing with emulsion fuel and dust combustion. The same tendency is confirmed even when sterilizing beyond the maximum sterilization time in Table 1.

Table 1

[0039] [Ignition property, combustibility test] Emulsion fuel was produced at the ratio shown in Table 2, and ignition tests and combustibility tests were conducted in the combustion chamber of an internal combustion engine. For emulsion fuel A, ignition occurred and combustibility was also confirmed. For emulsion fuel B, ignition property and combustibility comparable to those of emulsion fuel A were confirmed, but for emulsion fuel C, ignition did not occur in the combustion chamber of the internal combustion engine, and combustibility could not be confirmed in the combustion chamber of the internal combustion engine.

[0040] In the experiment with the above kerosene boiler, as shown in Table 2, for the emulsion without soil bacteria, the ratio of kerosene to water was 7:3, which was the limit for stable combustion. However, for the emulsion mixed with soil bacteria, combustion continued stably even when the ratio was 1:1. Soil bacteria grow and are sterilized under the above culture conditions, so those that meet the nutritional and environmental conditions have uniform particle sizes, have surface activity on the cell membrane, and are very compatible with water. Therefore, ideal soil bacteria water as a dust mixture can be obtained.

Table 2

[0041] 〔Embodiment 1〕 This embodiment will be described with reference to FIG. 1. FIG. 1 is a diesel engine for a generator. 101 is a fuel tank, 102 is a mixing tank, 103 is a soil bacteria water tank, 104 is a spray nozzle, 105 is a cylinder head, 106 is a combustion chamber, 107 is a piston, 108 is diluted soil bacteria water, 109 is liquid fuel, and P is a liquid delivery pump. The method for generating the diluted soil bacteria water is the same as described above.

[0042] Suppose the diluted soil bacteria water 108 and the liquid fuel 109 are mixed and stirred in the mixing tank 102 at a ratio of 1:1 to form an emulsion fuel. After the temperature in the combustion chamber is raised above the ignition point by the piston 107, the emulsion fuel is injected from the spray nozzle 104 into the combustion chamber 106 by the liquid delivery pump P.

[0043] 〔Embodiment 2〕 This embodiment will be described with reference to FIG. 2. FIG. 2 is a diesel engine for an automobile. 201 is a fuel tank, 202 is a soil bacteria water tank, 203 and 204 are spray nozzles, 205 is a cylinder head, 206 is a combustion chamber, 207 is a piston, 208 is diluted soil bacteria water, 209 is liquid fuel, and P is a liquid delivery pump.

[0044] The method for generating the diluted soil bacteria water is the same as described above. Regarding the concentration of the emulsion fuel, when at high power, the liquid fuel 209 and the diluted soil bacteria water 208 are controlled by the liquid delivery pump P so that the ratio is 7:3, and when at low load, the ratio is controlled to be 1:1. The ratio is variably adjusted between 7:3 and 1:1 according to the load magnitude.

[0045] Suppose the diluted soil bacteria water 208 and the liquid fuel 209 are mixed and stirred in the soil bacteria water tank 202 at a ratio of 1:1 to form an emulsion fuel. After the combustion chamber is heated to a temperature above the ignition point by the piston 207, the emulsion fuel is injected from the spray nozzle 204 into the combustion chamber 206 by the liquid delivery pump P.

[0046] [Embodiment 3] The mixed water obtained by removing the surfactant from the aforementioned diluted soil bacteria water was spray-mixed into the intake port of the heating kerosene boiler installed in the cultivation house. (Not shown.) Note that the amount of the mixed water sprayed into the combustion chamber may be adjusted by a sensor module for checking the combustion status of the combustion chamber in the internal combustion engine, a temperature sensor module of the combustion chamber, etc.

[0047] Since water vapor has absorption and radiation bands in the infrared region with a wider wavelength range of the greenhouse effect compared to carbon dioxide, when water is added to the combustion chamber and the amount of water vapor increases, the amount of water vapor discharged from the boiler increases. Even if the exhaust is diluted with water vapor and the temperature decreases, the amount of infrared radiation in the medium and long wavelength ranges radiated by the exhaust water vapor increases, so the fuel consumption can be reduced by 40%. Also, in the case of humidification by a humidifier in the house, there is a possibility that water droplets may adhere to the crops in the house and damage the commercial value. However, in this embodiment, no water droplets adhered to the crops in the house.

[0048] The amount of fuel consumed and the amount of carbon emissions can be reduced by the water mixing effect using the dust combustion effect. In internal combustion engines, it can be used for engines and gas turbines. In engines, it can be used for marine diesel engines with low rotational speeds and engines for power generation. In internal combustion engines, an energy-saving effect of reducing the exhaust gas temperature can be produced. When used in ships, a more effective effect can be exerted by combining a fresh water generator using ultrafiltration with the internal combustion engine.

[0049] Solid fuels such as coal and coke are pulverized and burned. However, when the particle sizes are uneven and a large amount of water is added, there are powders with a diameter of 100 μm or more that are difficult to burn only by dust combustion, so the combustion becomes unstable and carbon monoxide is known to be generated. By mixing the soil bacteria water of the present invention with uniform particle sizes into the combustion chamber, combustion can be stably carried out even when water is added, and the generation of carbon monoxide is suppressed.

[0050] (Experiment on improving ignition of solid fuel) An experiment was conducted in a ventilated plastic greenhouse. A net was laid on the combustion part of an oil gas burner device using kerosene as fuel, and coal was placed on it and ignited. The temperature of the combustion part of the outer flame and the concentration of carbon monoxide were measured. When the coal started to burn, the temperature of the combustion part of the outer flame of the oil gas burner device was 396 - 400 °C, and the concentration of carbon monoxide in the plastic greenhouse was 17 - 20 PPM. On the other hand, when the same experiment was conducted with the diluted soil bacteria water prepared under the above conditions being sprayed with a humidifier, when the coal started to burn, the temperature of the combustion part of the outer flame of the oil gas burner device was 340 °C - 352 °C, and the concentration of carbon monoxide in the plastic greenhouse was 0 - 5 PPM.

[0051] (Experiment on improving ignition of liquid fuel) An experiment was conducted in a ventilated vinyl house. With the humidifier spraying water, an oil heater using kerosene as fuel was ignited, and the temperature of the outer flame and the concentration of carbon monoxide were measured. The temperature of the outer flame of the oil heater was 385°C to 400°C, and the concentration of carbon monoxide in the vinyl house was 9 to 20 PPM. On the other hand, when a similar experiment was conducted with the diluted soil bacterium water prepared under the above conditions being sprayed by the humidifier, the temperature of the combustion part of the outer flame of the oil gas burner equipment when the coal started to burn was 340°C to 358°C, and the concentration of carbon monoxide in the vinyl house was 0 to 5 PPM.

[0052] From the above experiment, when the diluted soil bacterium water was sprayed, ignition occurred at a lower temperature than when it was not sprayed. Therefore, the ignition improvement effect of solid fuel and liquid fuel was shown. Also, when the diluted soil bacterium water was sprayed, the generation of carbon monoxide was suppressed compared to when it was not sprayed. Therefore, the combustion stability effect of solid fuel and liquid fuel was shown.

[0053] The present invention has been described in detail with the above examples, but the present invention is not limited thereto. Also, the configurations and processing functions described in the above embodiments can be arbitrarily combined by selection, and it is obvious that those skilled in the art can adopt modified forms based on the technical concept and teaching of the present invention.
