Description

V. Description of the Invention (1) The present invention provides a fuel and water / combustion combustion equipment, which is a device for separately storing fuel oil and water, such as kerosene, heavy oil, and water, and then spraying them to the mixing chamber 2 to burn them. Furthermore, it is a combustion device that can increase the proportion of mixed water in fuel without extinguishing it to save fuel consumption.

According to the conventional method, there are two ways to mix fuel and water for combustion. The first is to add water to the fuel and then add surfactants and other emulsifying aids to make an aqueous emulsion with a water-to-fuel ratio of 3_20v0e%, that is, to turn the oil into an emulsion state. 'Combustion' is therefore called emulsion combustion. In this emulsion combustion method, the water droplets dispersed in the oil will vaporize and expand due to heating, which will violently destroy the oil droplets and further cause the reaction of water and gas, which will increase the temperature of the flame. Compared with the 'combustion method', this emulsion combustion method will make the fuel easier to burn, reduce the emission of harmful nitrogen oxides, etc., and reduce the amount of coal dust.

The emulsion combustion method described above, the method of mixing fuel water and surfactant is to add water or surfactant to the fuel; and then add oil or water to the fine water droplets by stirring or ultrasonic vibration. Disperse water droplets in oil to form an emulsion. However, this mixing method is not only a complicated process, but because the quality of the oil is relatively light, the well-mixed emulsion will be destroyed in the preservation state, so that the oil and water are separated; when a large amount of water is injected and the viscosity is reduced, the oil is heated in advance Shi's original balance of maintaining the state of the emulsion will thus collapse. As described above, when the emulsion is damaged, the oil-water phase is separated or close to the phase separation. The degree of separation will deteriorate the emulsified state and increase the water particles. So that the purpose of pre-jg tiny water droplets can make the oil droplets react explosively, it is difficult

说明 Description of invention The second known method is to mix fuel and water for combustion, in which the fuel is sprayed and mixed in the furnace in accordance with the prescribed ratio. This type of mixing can be performed in a smaller combustion furnace. . The principle is that the oil in the gasifier and the air passing through the nozzle of the water vapor are sprayed into the mixer together. The oil and water vapor in the mixer will form a vortex to promote combustion. The ratio of water to fuel can be increased to 20-40 V〇e%, which can further reduce fuel consumption. Among them, "the second conventional method of burning fuel oil and water food m, the first conventional emulsion combustion method can also achieve complete combustion of fuels and the like", and can reduce the production of harmful gases such as carbon monoxide and nitrogen oxide, and Salty smoke. Therefore, in the long run, the 'combustion method of mixing water and fuel oil' will have the advantage of making it difficult for tar and carbon to adhere to the wall of the burner or the furnace ', which means that this combustion method does not easily generate soot, and In terms of combustion efficiency, there is also the advantage of improving combustion efficiency. The heat generated during the conversion of carbon monoxide to carbon monoxide is greater than the heat required when water becomes free radicals. The argon produced by ammonium is oxidized. Therefore, the flame temperature is higher than that of ordinary fuel alone. Also, the air can be temporarily reduced to the lower limit 'so that the heat loss during exhaust can be reduced. The burner 'published in Japanese Patent Application Laid-Open No. 3- 1 48506' is a 27th conventional machine that mixes fuel and water by injection, and its combined cross-sectional view is shown in the fourth circle and shown in the fifth figure. The display is a combination of the main parts of the invention of the burner. As shown in the fourth and fifth figures, the second method mixes fuel and water injection.

The structure of the combusting device is such that the supply end is connected to the oil tank (not shown) and one end of the pipe 32 is connected; as for the nozzle part 19 below the oil pipe 16 is connected. The fuel sent from the tank to the oil inflow pipe 22 indicates the fuel flow direction. The liquid fuel oil supply main pipe 34 has one end at the other end via the valve 33 and the oil inflow pipe 32 at the other end with the gasification of the valve 33. In order to adjust the fuel supply amount, the first figure One end of the water supply main pipe 38 for providing liquid water in the same sleepy type shown by the arrow is connected to the water tank (not shown), and the other end is connected to one end of the water inlet pipe 36 through the valve 37. Among them, the valve 37 is used to adjust the supply of water into the water tank. Among them, the aforementioned [the gasification tube 16 is a container for gasifying oil and gas by using the heat generated during combustion, and its shape is set to surround the furnace 31, and the nozzle portion 21 above the gasification tube 16 A gasification oil supply pipe y will be connected, which is mainly used to output the gasification oil produced by gasification of the gasification pipe 丨 6. The end of the gasification pipe 16 will penetrate the upper plate of the ventilation pipe 14 and the inside of the protection box ι8. Oil spray nozzle 24 phase connection》

The same 'f gasification tube 17 is also a container that vaporizes water by the heat generated during combustion. It is opposite the oil gasification tube and is set around the furnace 31. It is connected to one end of the gasification water supply tube 25. . The vaporized water supply pipe 25 is connected to the upper nozzle portion 22 above the water vaporization pipe 17, and the water vapor generated by the vaporization of the water vaporization pipe 17 can be discharged, and the end of the vaporized water supply pipe 25 will pass through. The upper plate of the ventilation pipe 14 is connected to the water injection nozzle 26 inside the protection box 18. The oil spraying nozzles 24 and the water spraying nozzles 26 are sprayed toward the mixing chamber 29. The mixing chamber 29 is provided in the L-shaped body acoustic curve of the support body 28 supporting the hot plate.

"At one end" and the fuel and water injected in the gasified state of the mixing chamber 29 will rise from the air inside the support 28 and flow into the hot plate 12, and then spray from the vent 13 into the furnace 31 for combustion "Λ above The second method of mixing fuel and water in the furnace in a prescribed ratio is compared with the first method of emulsion combustion. The second method will increase the ratio of water to fuel the fuel. The advantage of reducing the amount makes it possible to further destroy the oil droplets and the appropriate water-gas reaction. It is easy to completely burn the fuel and can reduce the generation of nitrogen oxides and reduce the amount of soot. 'But' If you want to increase the proportion of water, There will always be fire. If the flameout situation is to be improved, it is solved by the prevention method of adjusting the primary air and the secondary air. However, this solution is troublesome. In view of the above-mentioned conventional method of mixing fuel and water in a furnace in a prescribed ratio, the above-mentioned shortcomings that are easily extinguished due to an increase in the amount of water and are not easy to solve are improved designs. A number of experiments have been done on the above problem of easy flameout. The results of the experiments are to increase the temperature of the steam burning with fuel oil to become superheated steam, which can increase the ratio of water to fuel oil and increase the water to 50 ~ 70V. % Without causing total fire, '. According to this fact, when the heat to the water vaporization tube has not been sufficiently moved in the early stage of combustion, that is, when the temperature of the steam ejected from the water nozzle is still low, do not make the proportion of water too high, and at the same time when water is vaporized When the temperature of the tube rises, the ratio of water to fuel can be increased. When the water nozzle sprays superheated steam, it has a high oil-water ratio, which can provide high-efficiency oil-water co-firing without flameout.

V. Description of the invention (7) Oil and water mixing equipment, including: Fuel tank 1 and key water tank 2 'The fuel and water inside the two tanks are all driven by a motor (not shown in the figure). The water fountain 4 controls its flow. And this flow will be controlled by a control unit 5. In addition to being able to control ON and OFF, it can also be stopped urgently when abnormal conditions occur. The control method of the control unit 5 is based on the temperature of the oil sprayed from the oil gasification tube 16 and the temperature of the water vapor sprayed from the water gasification tube 17 to control the flow of fuel and water. The source of the temperature value of the water vapor is obtained from the temperature sensors 6 and 7 preset on the gas outlet pipe 16 and the water gasification pipe 17 ejection outlet pipe.

Oil inlet pipe 32. and water inlet pipe 36 '. One end of the oil inlet pipe 32 is connected to the oil tank 3, and the other end of the oil inlet pipe 32 is connected to the lower nozzle portion 19 of the oil gasification pipe 16 constituting the fuel heating portion; The two ends of the water inlet pipe 36 are respectively connected to the water OPp tube 4 ′ and the lower nozzle part 20 of the water vaporization pipe 17.

The oil gasification tube 16 and the water gasification tube 17 are opposed to each other in the form of a cylinder 'to form the surrounding wall of the furnace 31. Among them, the fuel heated by the gasification pipe 6 is output from the nozzle 21 above the gasification pipe 16 after gasification, that is, it becomes gasified oil output, and then enters the mixing chamber 29 through a gasification oil supply pipe 23 The oil was sucked 24 'and was sprayed out. At the entrance of the mixing chamber 29 around the oil nozzle 24, it is necessary to introduce the first air in order to burn. The tip of the oil nozzle 24 is provided with a ring-shaped gap as if it is surrounded. Below the furnace 31 is provided an opening 15 through which secondary air can be introduced. As for the 'water gasification tube 17, the water heated by the water gasification tube 17,

V. Description of the invention (8) After the gasification into water vapor, the water pipe mouth portion 22 and the end of the steam delivery tube 8 and the mouthpiece portion 10 enter the water vapor to be heated into a spiral tube made of superheated steam. The upper part of the cylinder with the same caliber gas passes through the superheating pipe 9 to overheat the heat pipe 9 and the nozzle 11 is sent to the water spray nozzle 26 set up with the gasified water and the fuel is further discussed in detail. The composition of the oil and gas can also be used; In addition, the above-mentioned superheating tube 9 is a cylinder formed by the above 17, and it is also indispensable if the upper side of the furnace 31 which does not hinder the combustion of the product. The equipment composed according to the above structure operates in the following heating manner, which will reduce the viscosity of the fuel well, and become smaller than the water vapor heated in the embers 17 to enter from the water nozzle 26, that is, the chamber 2 9 and Comparing the state where fine particles of oil and gas are heated to high-temperature water vapor, for fuel oil, even if the vapor is lifted, it will also go to the upper tube 8 of the water gasification tube Π, and then the water vapor will be sent from the steam to the superheated tube 9, the superheated tube. 9 can be used to be. The superheating pipe 9 is formed by winding a heat-resistant high-gold oil-gasification pipe 16 and a water gasification pipe 17 (as shown in the second figure). After the water has been steamed into superheated steam, it passes through the supply pipe 25 and enters into the mixing chamber 29 together with the oil nozzle 24. The gasification tube 16 and the water gasification tube 17 may be formed in a stepped or spiral path from a single tube. The gasification tube 1 may be installed in a manner that the water gasification tube is coiled according to the diameter of the cylinder, but if it is discharged, The present invention can also be provided with the superheating pipe 9. First, the internal combustion superheat pipe becomes a mixture of high temperature drops) and high-brightness fuel. First, the fuel oil is sprayed from the fuel. The other side is 9 and becomes Xiao Xiaolu. This kind of non-passing heat will not be burned in the mixture with water on the state surface of the gasification tube 16 being sprayed by the nozzle 24. It will drop in the high-temperature water vapor in the water gasification tube, and it will be in a mixed state (ie, The water vapor phase of 9 flames out.

Page 11 V. Description of the invention (9) According to experiments, the effect of water vapor not passing through the superheating tube 9 and water vapor passing through the superheating tube 9 on flameout is compared. The experimental results are the same; if the equipment is made 'if water vapor is not allowed to pass through the superheating pipe 9, the limit of flameout is oil / 100 ·· water / 40; otherwise,' if water vapor is passed through the superheating pipe 9 to make it superheated steam , The flameout limit can be extended to oil / 100: water / 70. As shown in the third circle, the temperature of the warm fuel is fixed, and the temperature of the water vapor ejected from the water nozzle is changed to see how much the fuel-water mixing ratio affects the flameout. This is an example of an actual measurement chart. In the actual measurement, the horizontal axis is the ratio of the amount of fuel mixed water, and the vertical axis is the temperature of the water vapor sprayed from the water nozzle. Even if the amount of water mixed in the fuel increases, it will not flame out during combustion. Conversely, if the temperature of the water vapor ejected from the water injection is lowered, if the amount of water injected is increased, the flame will stop when it is burned. Therefore, when the water vaporization tube is insufficiently heated at the beginning of combustion, it is necessary to reduce the ratio of the amount of water mixed into the fuel oil by β 6 and set it at the temperature at which water is vaporized. . There will also be changes in the data. The data will be burned one after another, which will cause the oil gasification tube 17 to be ejected and will return to the control gas-> 38 seed oil of the motor. So changed. Temperature of Fire

Please refer to the 16 nozzle outlet pipeline shown in the first figure again; on the temperature transmission pipeline 'the temperature sensor system 5' enables the control unit 5 to calculate the fuel and watercraft movement from the value data to control the oil 0gp cylinder β and Water and combustion equipment have different structures. The control unit 5 should echo the results of the experiment as described above. Page 12 V. Description of the invention (10) Increase the temperature to the limit. Reduce the harmful gas produced by CO. It is suitable for high temperature. For the sake of being suitable, the plant is based on the above-mentioned state where the water vapor which can be steamed is heated, and the fuel is mixed with fine particles. The fuel is burned with water, which is lower, but as it is increased with the fuel, it is not possible. Compared with the amount of water added, it will burn completely after adding water. At the same time, the amount of water added will contain a large amount of clean and beautiful after the plant is burned. With the discharge of nitrogen oxide without the addition of water and a large amount of moisture on the dry and humid plant cultivation sheds, the stems and leaves of the plant water supply will be maintained. The structural description shows that the gas is reheated and overheated into superheated water. The vapours then combust. The superheat pipe is mixed with fuel, so the amount can be increased. At the beginning of the ignition and combustion, the prolonged burning time is compared with the amount of water added to maintain the stability of the combustion. The fuel at the flame temperature can reduce the CO and nitrogen and burn the moisture with the fuel when burning. The moisture-retaining components in the dry room incubation room and the greenhouse are free of oil, which will reduce the soot and dust in the room. And the wet wolf is beautiful. The invention is attached to a pipe, which is used to convert the superheated water jet into overheating. The continuous combustion is easy to burn, and the amount of humidity is adjusted. There is no water vaporization pipe in the warm room for special temperature. The water that is injected into the mixer vapor through the nozzle of the water vaporization tube is in a burned state and η, and the ratio can be increased by β, and compared with the single-oxide combustion, the impurities will be warmed and the fuel will be mixed. The water is added in a way that the pure fuel is discharged and reduced without burning out. It has a humidity-controlling use that increases the amount of water that can be kept. Compared with the fuel in the state of fire, it is easier to lighten the fuel. The role of the media smoke and dust is to release the gas.
