Description
The present invention relates to a system for burning a mixed fuel of a water electrolysis gas (also referred to as oxyhydrogen gas or brown gas or HHO) and water vapor, and a fuel mixed with the mixed fuel and a conventional fossil fuel, A mixed fuel obtained by mixing an electrolytic gas and water vapor and a system for burning the same, and a system for burning a fuel obtained by mixing a water electrolytic gas, water vapor and an existing fossil fuel.
Recently, the global energy problem seems to be in a very important phase of adjustment either in terms of policy or technological development. This is due to the seriousness of global warming caused by fossil fuels that have risen sharply over the past 50 years, and the growing anxiety due to the absence of energy problem solving caused by the Chernobyl and Fukushima nuclear accidents.
As part of the countermeasures to this end, it is important to utilize fossil fuels efficiently and to discover more powerful new renewable energy as one of the central theme in the energy field.
It is getting higher.
What is being attempted in recent years as a trend is water decomposition gas generated by so-called electrolysis of water. That is to say, the feasibility of this mixed gas, also called brown gas or HHO gas, as a fuel, and the technique of directly burning or blasting it in an automobile engine or other combustion device or incinerator have been tried in various fields at home and abroad Is being announced
As is well known, when water is electrolyzed, it occurs in the form of a mixture of 1860 times H2 and O2 gases in a volume of 1 liter of water.
Water electrolysis gas is called Brown gas or HHO gas since Yull Brown started research on energy field in earnest in 1977.
However, many people who study water electrolysis gases over-emphasize specificities such as ultra-efficiency or thermonuclear reactions that are not scientifically fully proven for such water electrolysis gases, so that instead of normal use of water electrolysis gases as energy, . ≪ / RTI >
The water electrolytic gas is a gas which is produced by the electrolysis of water and mixed with hydrogen and oxygen at a complete equivalent ratio of 2: 1, and is a completely non-polluting fuel which is reduced to a steam state after combustion. That is, carbon dioxide which is a warming gas or nitrogen oxide which is an acid gas is not generated.
In addition, the water electrolytic gas has a characteristic of completely burning in a very short time due to its own oxygen even if it does not supply air serving as an oxidizer like existing fossil fuel because hydrogen and oxygen have a condition of complete combustion of 2: 1. In addition, since there is no nitrogen which is essential for the oxidizing agent such as air and which does not help the reaction, the heating ability for the product generated in the combustion is three times as large as that of the gasoline combustion by the air. Therefore, the electrolytic gas is utilized as a useful tool in the welding field where the high temperature is required especially since the hot flame temperature is as high as 3000C.
The advantage of such a water electrolysis gas is that the hydrogen energy obtained by electrolysis of water is smaller than the energy used in electrolysis (60-80% efficiency), but it does not contain nitrogen as an oxidizing agent in burning, (Power = work / time) or the possibility of being a clean fuel is high in that it takes a long time to emit a large amount of energy in a short time.
In addition, the water electrolytic gas reacts with one molecule of hydrogen and one-half molecule of oxygen during combustion to produce one molecule of water, so that the number of moles of the product decreases compared to the number of moles of the reactant
In a special situation where the temperature is high and the expansion effect due to Bohr's Law is not conspicuous, the volume may be reduced, which may result in an impulsive characteristic.
In addition, since the water electrolytic gas is completely premixed with hydrogen and oxygen at an equivalent ratio, not only the process of mixing the fuel and the oxygen in a turbulent manner is required but also the hydrogen molecule has a molecular diffusivity, It is very fast.
Therefore, the flame has a back-fire characteristic that burns in the direction of fuel supply.
In order to prevent such backflushing, it is necessary to increase the speed of the fuel jetted from the nozzle, so that the flame is inevitably formed by a very unstable pin point flame which advances a very long and long flame or is easily extinguished by a lift-off phenomenon . This feature is an obstacle to using water electrolysis gas more easily and practically.
In this way, the electrolytic gas, which can be mixed with hydrogen and oxygen by the electrolysis method, requires a new combustion method unlike the conventional burner or the combustion method because of the backlash or unstable characteristics of the flame.
The water electrolytic gas, which is generated by electrolysis of water and premixed with hydrogen and oxygen at an equivalence ratio, is explosively reacted to cause back-fire or flame lift-off. flammability of the fuel and oxidizer, and temperature control to prevent ignition.
A water electrolytic gas combustion apparatus for solving the above problems and demands have been studied by many engineers and researchers.
Patent Document 10-0367223 (Water electrolytic gas boiler, hereinafter referred to as prior art) relates to a water electrolytic gas boiler for using fuel of a gas boiler as a fuel instead of LPG or LNG as a water electrolytic gas, And a water electrolytic gas boiler equipped with a heating part and a circulating combustion chamber to which four characteristics of water electrolytic gas alone are applied in order to burn and generate decomposition gas.
It is an object of the present invention and an object of the present invention to provide an efficient use of water electrolysis gas using water vapor.
That is, the conventional water decomposition gas, the combustion device, and the prior art still have a problem of unstable flame in which back-fire or lift-off occurs, Fuel and a combustion system using the same.
In addition, conventional fossil fuels such as coal, oil, gasoline, diesel, kerosene, LNG, and LPG emit pollutants such as CO2, SOx, NOx and the like, Combustion system.
In order to solve the above problems and needs,
The present invention provides a combustion system comprising a water electrolytic gas generating device (200), a water vapor generating device (300), a gas mixing device (500), and a combustion device (400).
Further, the present invention provides a combustion system using mixed fuel obtained by mixing 100 parts by weight of water electrolytic gas with 1 to 1,000 parts by weight of steam.
The present invention also includes a water
Also, the present invention provides a combustion system using a mixed fuel composed of 1 to 1,000 parts by weight of a fossil fuel mixed with 100 parts by weight of a mixed fuel obtained by mixing 1 to 1,000 parts by weight of steam with 100 parts by weight of a water electrolytic gas .
Conventional technologies attempted to improve combustion efficiency and reduce pollutants by simply burning water electrolytic gas directly or with fossil fuel.
However, when the water vapor is not mixed, the amount of pollution-free electrolysis gas that can cope with the rapid increase of the flame temperature due to the rapid reaction of the water electrolytic gas and the excessive heating ability is absolutely restricted, do.
In this case, when the amount of the electrolytic gas is increased, the temperature rise is accelerated, and the problem of durability due to the generation and combustion of nitrogen oxides is further exacerbated.
Therefore, the mixed fuel of the water electrolytic gas and the water vapor according to the present invention, and the mixed fuel of the mixed gas and the fossil fuel and the combustion system therefor are very original, And to solve the problem.
If the effect of the present invention is illuminated from the viewpoint of combustion of conventional fossil fuels, conventional fossil fuels are a method of burning air (O2 + 3.76 N2) to fossil fuels, while the combustion method of the present invention is a method of water- (H2O vapor) is mixed with the gas (H2 + 1/2 O2), and the combustion gas is generated in proportion to the amount of the mixture of the water electrolytic gas and the water vapor and the generation of the acid gas by the nitrogen oxide (NOx) The generation of warming gas is controlled by source.
In addition, there is a coal-water slurry combustion technology that mixes liquid phases in conventional fossil fuels in comparison. The purpose of mixing and burning the water in the form of droplets is convenient for transportation and supply, and when the liquid water vaporizes, the mixture effect is enhanced by the strong volumetric expansion and the nitrogen oxide is reduced by the flame temperature lowering due to the heat of vaporization of water .
However, this method not only affects the stable formation of the flame due to the cooling down of the strong vaporization heat of water, but also the volumetric expansion effect due to the vaporization is a technique that is not continuously used because of negative factors such as a decrease in swirl force. Technology.
Therefore, it is judged that the water electrolytic gas and water vapor are different qualitatively from the technique of fusing with fossil fuel as in the case of the present invention.
In summary, the mixed fuel, mixed-composition fuel, and combustion system according to the present invention has the effect of providing an unstable and explosive electrolysis gas as a highly stable mixed fuel by mixing the water electrolytic gas, which is a clean fuel, with water vapor, By mixing and burning fuel, it is possible to significantly reduce pollutants such as CO2, NOx, SOx and the like which are problems of fossil fuel in proportion to the decrease of the amount of fossil fuel.
In addition, when a mixed-type fuel and combustion system according to the present invention is used to completely incinerate a refrigerant such as Freon with excess air, a large amount of water vapor introduced in the present invention is discharged through a deacon reaction It converts toxic fluorine or chlorine gas into less toxic hydrofluoric acid or hydrochloric acid.

The present invention provides a mixed composition fuel comprising water electrolytic gas, water vapor, and fossil fuel comprising the above structure and function, and a combustion system for burning the fuel.
The present invention was conceived through a computational analytical method for the mixed fuel and the method of combustion of the mixed fuel according to the invention as described above. As a result, compared with the conventional method of burning water electrolytic gas, It can be seen that there is a remarkable effect in terms of
1. Experimental Method
In the present invention, combustion characteristics of a conventional LNG fuel and combustion characteristics of a mixed fuel obtained by mixing a water electrolytic gas and water vapor are quantitatively investigated in a kiln type combustion furnace. In particular, the ratio of water electrolytic gas and water vapor is controlled Flame stability and flow characteristics were investigated.
2. Experimental apparatus for combustion characteristics
The characteristics of the burner and the furnace for the kiln for cement drying by the combustion characteristic test apparatus are shown in Figs. 6A to 6C.
3. Experimental results
(1) Combustion characteristics of LNG fuel and mixed fuel mixed with water electrolytic gas and water vapor were investigated quantitatively in a kiln type combustion furnace.
(2) Calculation conditions of LNG fuel are as shown in [Table 1] and the flame characteristics of LNG fuel are as described below.
FIGS. 7A and 7B are the results of numerical analysis of the internal heat flow of the combustion furnace when only LNG is injected as fuel. The fuel and air were injected by turning the primary fuel injection port and the primary air injection port, and the fuel injection port and the secondary air injection port were injected with fuel and air without turning.
The firing air was injected at a temperature of 220 ° C through the 16 nozzles at the edge with a combustion amount of 10,000
Referring to the flow distribution shown in FIG. 7C, it can be seen that a recirculation zone is formed at the center of the combustion furnace (CTRZ) by the swirl effect in the vicinity of the burner. The average flow rate at the exit was about 15.94 m / s.
(3) Based on the results of the above calculation of LNG fuel, the characteristics of the flame varying by controlling the amount of water vapor and the amount of water vapor are examined to determine whether a stable flame can be obtained by mixing water electrolytic gas and water vapor. The characteristics of the water electrolytic gas and the steam collision flame were compared with the LNG flame.
Table 2 below gives the conditions used for variable studies. In the variable study, the reference flame was set as LNG flame (Case 1). Various methods can be used for comparison with such LNG flames. Specifically, for example, there is a method of equalizing the calorific value, and a method of controlling the flow rate and momentum of the nozzle may be used. However, if the amount of heat is the same, the temperature of the flame may be substantially different if the type of product and the number of moles differ.
Therefore, in this experiment, we first consider the heat value, the number of moles and the specific heat of the product (case 1) when the temperature of LNG flame (Case 1), water electrolysis gas and water vapor amount are mixed 1:
And the temperature of the flame was set to be similar. In
In the central burner corresponding to the primary inlet, the amount of water electrolytic gas and water vapor was fixed to 1: 1, and the amount of water vapor to the water electrolytic gas in the secondary burner located around the primary inlet was doubled The characteristics of the flame and the change of the temperature were investigated. In the case of the LNG flame used in the above verification, firing air was used. However, in this case, no firing air was injected to observe the flame characteristics while excluding the effect of the firing air on the flame. Also, a sensible heat loss model was used for the wall.
(4) Experimental results
1) In Figure 8a, Case 1 (case 1) and Case 2 (Case 1), in which the combustion temperature is set to be similar to that of
In this case, the temperature of the outlet is 1594 ℃ for Case1 and 1588 ℃ for Case2.
However, the distribution of temperature inside the flame was found to be relatively wide and gentle in the case of LNG flame, whereas the flame temperature gradient was formed substantially in the case of fuel mixed with water vapor and water electrolysis gas.
This is because although the water electrolytic gas is mixed with water vapor, the water electrolytic gas itself is stoichiometrically totally premixed with hydrogen and oxygen. Therefore, the turbulent flow in which the reaction is determined by the mixing rate of the oxidant and the fuel , But it is considered that the reaction proceeded relatively quickly.
2) In FIG. 8b, the velocity fields for the above four cases are presented. In the case of LNG flames, it is evident that a strong central recirculation zone is formed by the swirling flow, but in the case of the water electrolytic gas and the steam mixture, the central swirling flow is not generated despite the same swirling intensity . This is presumably due to the effect of the initial flame expansion due to the rapid chemical reaction of the water electrolytic gas.
3) The above results show that pre-mixing of water electrolytic gas and water vapor makes it possible to control unstable combustion characteristics such as flame reversal and thin flame or flame lift-off while maintaining the function of clean fuel.
In addition, combustion characteristics of water electrolytic gas and water vapor mixed fuel were stable and physically consistent. Therefore, the mixed fuel of water electrolytic gas and water vapor suggests the potential as a clean fuel without emission of nitrogen oxides or other pollutants.
When a mixed-type fuel and a combustion system according to the present invention is used to completely incinerate a refrigerant such as Freon with excess air, a large amount of water vapor introduced in the present invention is highly toxic fluorine generated by a deacon reaction Or chlorine gas into less toxic hydrofluoric acid or hydrochloric acid.
The present invention provides a mixed fuel, a mixed composition fuel, and a combustion system using the same, wherein the structure, function, action, and effect described above are exhibited.
