Currently, various kinds of boiler heating oils are used in the various industrial fields. For example, bunker-C oil and soft coils have been conventionally used as fuels for heating boilers. However, since they tend to cause severe environmental pollution, their use is avoided in the industrial field. Further, heating oils such as paraffin oil and light oil are expensive and often cause severe financial difficulty in the industrial fields. Therefore, there is a need of more inexpensive alternative fuels for the industry.
In terms of fuel efficiency, however, conventional alternative fuels fail to replace petroleum, which continues to increase in price.
In particular, there is a need of a method that allows inexpensive fuels, such as wasted oil, bunker-C oil, and the like, to be processed to environmentally friendly alternative fuels.
SUMMARY OF THE INVENTIONThe foregoing and other features, utilities and advantages of the invention will be apparent from the following more particular description of a preferred embodiment of the invention as illustrated in the accompanying drawings.
The present invention is conceived to solve the problems of the conventional techniques as described above, and an object of the present invention is to provide an alternative emulsified fuel that comprises bunker-C oil and carbide (CaC2) as major raw materials, and water (H2O), in order to obtain cost reductions when utilized in various industrial fields.
It is another object of the present invention to provide an alternative emulsified fuel that can be produced by sufficiently mixing water with oil to form a compound, in which water and oil are highly coagulated with each other such that the emulsified fuel can be burnt with the compound of the water and oil highly coagulated with each other, in order to obtain cost reduction in applications of the industrial field through reduction in manufacturing and supply costs.
In accordance with one aspect of the present invention, the above and other objects can be accomplished by the provision of an alternative emulsified fuel, comprising: 0.5˜2 parts by weight of calcium chloride; and 100 parts by weight of a mixture, the mixture being formed by mixing 70˜80 wt % of bunker-C oil with 20˜30 wt % of carbide aqueous solution formed by dissolving 0.1˜1 wt % of carbide in water.
In accordance with another aspect of the present invention, a method of manufacturing an alternative emulsified fuel comprises: forming a mixture of bunker-C oil and carbide aqueous solution by mixing 70˜80 wt % of bunker-C oil with 20˜30 wt % of carbide aqueous solution, followed by heating and stirring the mixture; applying ultrasonic waves of 20 kHz 1 MHz to the stirred mixture for 20˜30 minutes; adding 0.5˜2 parts by weight of calcium chloride as an emulsification agent to 100 parts by weight of the mixture of the bunker-C oil and the carbide aqueous solution, followed by rotating the mixture at a high speed of 1,000˜1,200 rpm in an emulsifying machine for emulsification treatment.
The above and other objects, features and advantages of the present invention will become apparent from the following description of exemplary embodiments given in conjunction with the accompanying drawing, in which:
Exemplary embodiments of the present invention are described in detail with reference to the accompanying drawing hereinafter.
First, raw materials for an alternative emulsified fuel according to an embodiment of the present invention are described.
To produce the alternative emulsified fuel according to the invention, first, bunker-C oil, carbide aqueous solution formed by dissolving carbide (CaC2) in water, calcium chloride (CaCl2), an ultrasound machine, etc. are prepared.
According to the invention, calcium chloride and carbide aqueous solution serve to lower the viscosity of bunker-C oil, and ultrasonic waves serve to prevent oil-water separation in the mixture caused by a chemical reaction between materials, which can be added later.
Hereinafter, the bunker-C oil, the carbide aqueous solution, and calcium chloride are described in terms of a mixing ratio.
According to the invention, the alternative emulsified fuel comprises 0.5˜2 parts by weight of calcium chloride, and 100 parts by weight of a mixture that is formed by mixing 70˜80 wt % of bunker-C oil with 20˜30 wt % of carbide aqueous solution. The carbide aqueous solution is formed by dissolving 0.1˜1 wt % of carbide in 99˜99.9 wt % of water (H2O).
Such a mixing ratio of bunker-C oil and the carbide aqueous solution is determined to reduce manufacturing costs by forming a compound that contains water in an amount of about 20˜30 wt % to act as a part of an alternative fuel corresponding to the amount of water in the alternative fuel. Since an excessively added amount of water causes reduction in efficiency of the alternative emulsified fuel as a fuel, the aforementioned mixing ratio is determined to be suitable for the alternative emulsified fuel.
Further, calcium chloride serves as an emulsification agent to maintain unmixable bunker-C oil and water in a stable emulsion state and can obtain its desired function as the emulsification agent when mixed in the ratio described above.
With such ratios as described, the emulsified fuel has can be used as an effective alternative fuel due to its high efficiency as a fuel and characteristic of producing little soot in combustion.
Next, a method of manufacturing an alternative emulsified fuel according to an exemplary embodiment of the present invention is described.
According to the invention, 70˜80 wt % of bunker-C oil is first mixed with 20˜30 wt % of carbide aqueous solution. A mixture of the bunker-C oil and the carbide aqueous solution tends to prevent spontaneous, uniform coupling between materials, which tend to be mixed with each other. Thus, to facilitate a chemical reaction between the materials, which will be added after mixing 70˜80 wt % of bunker-C oil with 20˜30 wt % of carbide aqueous solution, the mixture is heated at 70˜100° C., and more preferably at 80˜90° C.
While heating the mixture, the mixture is stirred at 90˜120 rpm in a vacuum for 10˜30 minutes using a vacuum mixer.
Here, it is believed that ionic bonding is more actively induced between molecules constituting the respective compounds by rotating the mixture within the vacuum mixer along with the heat treatment at 80˜90° C. as described above.
After heating the mixture for about 30 minutes, preferably, ultrasonic waves of 20 kHz˜MHz are applied for 20˜30 minutes to the mixture to further promote chemical bonding between the molecules by lowering the viscosity of the bunker-C oil and causing an active movement between the molecules, while the mixture is passed through the ultrasound machine.
After making sufficient ionic bonding between the molecules through application of the ultrasonic waves as described above, calcium chloride (CaCl2) is added as an emulsification agent to the mixture of the bunker-C oil and carbide aqueous solution, which is then rotated at high speeds in an emulsifying machine for emulsification treatment of the mixture. At this time, calcium chloride is added in an amount of about 0.5˜2 parts by weight to 100 parts by weight of the mixture of the bunker-C oil and carbide aqueous solution.
Although calcium chloride is described as being added to the mixture of the bunker-C oil and carbide aqueous solution after application of the ultrasonic waves to the mixture in this embodiment of the present invention, calcium chloride can be added to the mixture simultaneously with mixing the bunker-C oil with the carbide aqueous solution.
As described above, after making the sufficient ionic bonding between the molecules by heating and rotating the mixture of the bunker-C oil and the carbide aqueous solution, calcium chloride is added to the mixture of the bunker-C oil and the carbide aqueous solution, which is in turn rotated at high speeds, for example, 1,000˜1,200 rpm, for a predetermined time in the emulsifying machine for the emulsification treatment of the mixture. As a result, distinction between water and oil in the mixture becomes lost and large water molecules are divided into water molecules small enough to be coupled to oil molecules while preventing oil-water separation in the mixture, by which the water molecules are coagulated with one another.
With such mixing ratios and processes, the alternative emulsified fuel of the invention has a high efficiency as a fuel and produces a significantly reduced amount of soot in combustion.
On the other hand, a great amount of water required for formation of the carbide aqueous solution makes a chemical reaction with material, which can be added to the bunker-C oil and calcium chloride, and is then converted into a part of the alternative emulsified fuel, whereby an alternative fuel capable of replacing conventional fuels such as gasoline, paraffin oil, etc. can be produced.
The alternative emulsified fuel of the invention can be produced through the steps as described above, and contains a great amount of water, which is added in the step of preparing the carbide aqueous solution and facilitate conversion into the part of the alternative emulsified fuel.
As described above, the present invention provides the alternative emulsified fuel that can be produced by mixing the bunker-C oil, carbide aqueous solution and calcium chloride, heating and stirring of the mixture, applying ultrasonic waves of 20 kHz ˜1 MHz to the mixture to induce ionic bonding between molecules in the mixture, and rotating the mixture at high speeds in the emulsifying machine to prevent the oil-water separation, and that can replace conventional fuels, such as petroleum.
As apparent from the above description, the alternative emulsified fuel according to the invention enables significant cost reductions in the industrial fields.
Further, the alternative emulsified fuel of the invention enables savings of expensive fuels such as gasoline and the like, and can significantly reduce an amount of environmentally unfriendly materials, which can be generated by burning.
Further, the alternative emulsified fuel of the invention contains water added in an amount of about 20˜30 wt % to act as a part of the alternative emulsified fuel corresponding to the amount of water in the alternative emulsified fuel, whereby an alternative fuel capable of reducing use of expensive fuels can be produced.
Although the embodiments and their effect of the present invention have been described, the present invention is not limited to the embodiments and effects described above. It should be understood that various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present invention defined by the accompanying claims.
