Summary of the Invention The emulsion fuel according to the present invention is prepared by emulsifying about 55 to 90 % by weight of a mixture of heavy oil, 45 to 10 %
by weight of water, and 0.3 to 0.8 % by weight of a catalyst. The catalyst comprises caustic soda (sodium hydroxide) and calcium dichloride in half and half. The calcium chloride can be partly substituted with calcium sulfate.
Detailed Description of the Invention The emulsion fuel according to the present invention stems from green pine leaves that commonly used as a winter fuel in some agricultural districts of Korea.
The green pine leaves comprise 90% of water, and 10% of pine oil and other minimal organic combustibles. Because the green pine leaves burn very actively and have a high thermal efficiency during combustion, they are suitable for the Korean under-floor heating system.
Just as the green pine leaves comprises 10% of pine oil and 90% of water, the emulsion fuel of the present invention can be prepared by emulsifying common heavy oil such as bunker fuel oil C with water. Also, the catalyst compound of the present invention have invented owing to the property that a sodium hydroxide can be soluble oil in water and that calcium or bittern containing the calcium solidify proteins. By using the catalyst compound, a mixture of heavy oil and water can be emulsified in the present invention.
For example, the green pine leaves in which 10% of pine oil in 90% water is dissolved can be easily burned and have a good efficiency. However, in case of permeating 50% of water into completely dried pine leaves, the leaves did not get even ignited. The reason is that the permeated 50% of water exists as water itself, not a soluble compound of pine oil and water as in case of the green pine leaves.
The compound prepared by mixing 10 to 45 % by weight of water and 90 to 55 % by weight of heavy oil such as buucer fuel oil C and petroleum in the presence of the catalyst in accordance with the present invention is kind of combustible material different from water. The molecule structure of the catalyst comprises an alkyl part that is affmitive with oil and a part that is affmitive with water, that is, the catalyst has both a hydrophobic and a hydrophilic group. Thus, between an oil layer and a water layer, because of the catalyst having a hydrophobic group and a hydrophilic group, hydrophobic molecules is placed at the oil layer, hydrophilic . molecules at the water layer by attr action force. In consequence, the emulsification occurs to change properties of an interface or surface of water and oil by surface activities.
The catalyst of the present invention is composed of sodium hydroxide and calcium dichloride. The calcium dichloride can be partly substituted by calcium sulfate. Adding 50% of a sodium hydroxide aqueous solution into 50% of 'a calcium dichloride slowly through a netting fabric, a white compound whose shape is like a thickening agent is educed by chemical interaction between the sodium hydroxide and calcium dichloride. Drying the compound on a netting thread having good water permeability, it becomes minute powders that have no tastes.
The emulsion fuel according to the present invention is prepared by emulsifying with mixing 55 to 90 % by weight of heavy oil such as bwker fuel oil C
and petroleum and 45 to 10 % by weight of water, and adding 0.3 to 0.8 % by weight of catalyst. Adding 45 to 10 % by weight of water and the catalyst to fuel oil, the water is changed into minute droplets having less than 10 micron of diameter and the water becomes water droplets in oil. With the water dr oplets contained in the j etted oil droplet being heated and expanded in a furnace, the water droplets are vaporized explosively, disperse the emulsion fuel in all directions and then can facilitate complete combustion of fuel.
In general, the ultra-particle sized emulsion fuel can burn completely by reducing an amount of excess water and increasing the contact surface area.
And, a ' cooling reaction of fire by the latent heat caused by vaporization of water, and a reaction to carbon of water bring to reductive effect of combustion carbon.
Also, the contents of NOX and hydrocarbon are reduced by chemical and physical reaction thereof. The emulsion fuel has an excellent fuel supplying and j etting as a colloid.
When the emulsion fuel that contains oil and water droplet burns, the water droplet contained in the oil droplet is exploded and vaporized with being heated at high temperature and expanded rapidly. Then the water droplet is continuously exploded, the ambient fuel is dispersed minutely in all directions. Thus, the continuous minute explosive reaction brings complete combustion of the fuel.
The water droplet of the emulsion fuel has a diameter of about 10 microns, 10 to 30 % of water, and many of microns of water droplets in oil droplets.
For example, the number of water droplets having diameters of 3 microns is about when 50 microns is a diameter of an oil droplet of the emulsion fuel whose water contents are 20%.
In case of LPG, the combustion gas includes 19 to 20 % of water and that is similar with the emulsion fuel. The combustion efficiency of the present emulsion fuel is even higher than that of LPG gas.
The reaction formula of the water is C+H20 -> CO+HZ (+OZ) -> COZ + HBO, and that is the reaction of water gas. Water molecules react with fuel oil at high temperature and then CO and H are generated. The combustion efficiency increases due to the reduction of the carbons.
An oxidized nitrogen generated in combustion is almost NO and N02. Both NO and NOZ ar a called NOX. The water of the emulsion fuel having uniform particles, it prevents generation of local high temperature region and decreases combustion temperature by means of vaporization latent heat of 20 to 30 % by volume of water. The water particles then prevent generation of NOX with absorption of heat, and generation of local high temper ature r egion by reaction of carbon particles and water gas. This NOX reduction r esults in prevention of air-pollution.
When the emulsion fuel of the present invention is applied to domestic or industrial boilers, NOX generation can be reduced by 40 to 75 %. The expanded surface areas of the particle sized water droplet facilitate air-contact, and complete combustion can be accomplished with a little air contents and practically more than 50 % of smoke is reduced. Also, the concentration of smoke dusts is also reduced.
For the most part, adding 50 % of water decreases the concentration of smoke dusts by half. The emulsion fuel of the present invention can reduce pollution because of remarkable reduction of smoke and can reduce the energy fuel by 30% because of reduction of the excess air rate.
Generally, gas fuel burns with a transparent flame and heavy oil burns with a transparent and yellow flame, which is in the presence of floating carbons.
However, the present emulsion fuel burns like the gas fuel with a flame.
Adding water to fuel oil, an amount of combustion gases increase by multiplying a weight of added water by 22.4/18 (Nm3/kg). A temperature of the flame is decreased by about 100 °C when water is added by 30 to 50 %
based on combustion with 1.2 of lamp-oil over air. However, because the amount of combustion gases increase, a heat transfer effect is not decreased. The combustion gases generated by combustion of liquefied fuel (e.g. LPG or LNG) include about 13 % of water. By adding water to the fuel the water contents become 16 to 17 %.
The emulsion fuel has no courosion problem because the liquefied fuel that contains similar concentration of water with that of the emulsion fuel has no such lcind of problem. Although there is little heat loss occurred by the added water, the theumal e~ciency is increased owing to the decrease of air rate, smoke, pollution and so on, and the effect that can prevent NOX from being generated.
The emulsion fuel is dispersed in a burner actively and the rate of the combustion gets more faster since combustion flames of oil droplets that have ultra-particles with water becomes a single flame. Because the fuel becomes more minute particles and then is dispersed again, the particles of the water is exploded continuously by high temperature. Thus, complete combustion can be accomplished by forming combustion flame like complete particle gases.
The present invention may be better understood by reference to the following examples that are intended for the purpose of illustration and are not to be construed as in any way limiting the scope of the present invention, which is defined in the claims appended hereto.
