に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing a so-called emulsified fuel by adding water to a fuel oil to form a milky fuel.

てきているのが実情である。2. Description of the Related Art When burning fuel, there is an idea that a so-called emulsified fuel is obtained by adding water to fuel oil and emulsifying the fuel. When this type of emulsified fuel is made into an oil-in-water type, when it overflows or spills, it becomes difficult for it to flow as it is, thereby increasing the safety in handling. In the case of the water-in-oil type, dust and nitrogen oxides (NO
x) can be reduced, which is effective in preventing pollution. There have been many proposals for such emulsified fuel production methods and equipment, and some of them have already been put to practical use in boilers and the like, but when they are actually used, the expected exhaust gas purification effect can be obtained. At present, it is no longer used because it is not used or the handling is more complicated than expected.

いる。[0003] However, from the viewpoint of energy and environmental conditions thereafter, it has become a situation that only fuel emulsification technology can be expected for further reduction of NOx and reduction of dust, even after reheating. In that sense, next-generation fuel emulsification technology is now awaited.

いることが必要になる。By the way, in such an emulsified fuel, the generation of a high-temperature heat spot in a combustion flame is suppressed so that the generated NOx is reduced as much as possible, and a uniform temperature distribution is obtained at a temperature as low as possible. For the purpose of combustion, it is essential that the particle size of water droplets in the emulsified fuel be within a certain particle size distribution and that the water droplets be mixed so as to be distributed as uniformly as possible in the oil. Requirements. These requirements are necessary in order to reduce dust that is in a trade-off relationship with the generation of NOx. Therefore, when using the emulsified fuel, it is necessary that the emulsified fuel under such conditions is always secured.

みられた。In a conventional fuel oil emulsifying apparatus, when mixing water with fuel oil, a method of injecting water or steam into the fuel oil from a nozzle and mixing the fuel oil with a fuel oil pipe is used. And emulsifying while mixing with a mixing section or a mixer provided downstream of the mixing section while water is injected into the mixing section. However, these methods have a problem that they cannot withstand long-term use. In other words, in these methods, since small-diameter nozzles and the like are used for mixing water in the fuel pipe, substances such as impurities and scale contained in the original fuel and water may be contained in the nozzle or the pipe, or The flow rate changed due to adhesion and deposition inside the equipment in the piping, and in extreme cases, phenomena such as clogging and no flow were observed. In addition, if the shutdown period of the device is prolonged, the emulsified fuel and water, which had been in a well-mixed state, were separated from each other, and the separated water caused corrosion in piping and equipment, and further caused by the corrosion. The phenomenon that rust causes the same problem was observed.
【0006】そこで、本発明は、定常運転状態であると

ころが大きい。If, for example, an emulsified fuel that satisfies the initial conditions is produced and immediately used for combustion, the expected performance and function will be achieved. As is good when the fuel is manufactured and used, it is necessary to suspend the use halfway and leave the normally-emulsified fuel temporarily or for a considerable time. In such a case, the above-described conventional problems are exposed. That is, if the oil and water are separated and become abnormal in the emulsified fuel, which is supposed to be normal, and is used for combustion, it naturally appears as various problems such as poor ignition or poor combustion. The conventional disadvantages described above are:
In the production of conventional emulsified fuels, attention is paid to the production thereof, and this is largely due to insufficient or insufficient consideration for temporary stop during use and restart after stop.

It is intended to be normal.

いう心配が残ることになる。When the emulsified oil tank 18 is provided in this manner, it is necessary to ensure that the properties of the temporarily stored emulsified oil are normal, but if the emulsified oil is stored,
It is also assumed that the water in the emulsified oil is separated and accumulated at the bottom of the emulsified oil tank 18. Therefore, in the present device, the shutoff valve 1 is used as a circulating means for circulating the emulsified oil stored in the emulsified oil tank 18 through the emulsified fuel production device 7.
A suction pipe 18a provided with 6d and a return pipe 18c connecting the switching valve 8a and the emulsified oil tank 18 are provided. However, when the apparatus is started after a temporary stop in the separated state as described above, if this water is directly sucked from the suction pipe 18a and returned to the emulsified fuel production apparatus 7, the water content is too large, and There is a concern that the emulsified oil to be converted to the water-in-oil type will be phase-shifted to the oil-in-water type, and the intended purpose will not be achieved.

とされている。Therefore, in the present apparatus, in order to eliminate such a concern, as shown in detail in FIG.
Assuming that the separated water is allowed to accumulate from the bottom of the tank 8 to a certain height L1, the lower end of the suction pipe 18a of the emulsified oil tank 18 is opened at that portion, and the suction port 18d is formed as shown in detail in FIG. As shown in detail in FIGS. 3 and 4, a suction port 18b of an appropriate size is opened at a certain height L2 above the portion, and a water portion is separated from the opening. By inhaling the emulsified oil of
A configuration is adopted to prevent the water content of the emulsified oil sucked into a from becoming excessive. With this configuration, the existing emulsified oil sucked in so that the water content does not become excessive is returned to the emulsified fuel production device 7 to be readjusted to an appropriate emulsified oil property, and is again returned to the emulsified oil tank 18 via the switching valve 8a. And this cycle can be repeated as necessary.

る。According to the apparatus for producing an emulsified fuel according to the first aspect of the present invention, the emulsified fuel produced by the fuel emulsifying means is immediately supplied to the combustion apparatus, while the emulsified fuel is mixed with the emulsified water as required. By temporarily storing the emulsified fuel in the emulsified fuel tank so that it can be remixed with the fuel oil, the properties of the emulsified fuel used for combustion can be ensured regardless of the operating state of the combustion device. When using the temporarily stored emulsified fuel, all of the stored emulsified fuel is always used after passing through the fuel emulsification means, so that the property of the emulsified fuel is not normal. It is possible to eliminate the conventional problems caused by the supply, and furthermore, when regenerating the stored emulsified fuel by circulation through the fuel emulsification means, without changing the proportion of the emulsified fuel oil / water withdrawn from the emulsified fuel tank. Since the fuel can be recirculated to the fuel emulsifying means, the regenerating process of the emulsified fuel by the fuel emulsifying means can be made effective while ensuring the properties of the emulsified fuel.
