Description

Briquette Stove with Hot Water Boiler Structure {Coal Stove with a Boiler System}

Field of invention

The present invention relates to a briquette stove having a hot water boiler structure. More specifically, the present invention relates to a briquette stove having a boiler function by circulating hot water using heat generated from a stove by remodeling a conventional coal stove. In particular, the present invention relates to a briquette stove that can maximize the thermal efficiency in the place where you can install a stove, such as a plastic house in a rural.

Background of the Invention and Prior Art

Briquetting stoves are widely used in rural plastic houses, barns, restaurants, and shops. Briquette stoves are mainly used for stoves arranged up and down in 19 rows, and stoves arranged up and down in three stages of three 19 balls. The present invention is a reconstruction of a briquette stove in which 19 coals are arranged up and down in three rows, and three briquettes are arranged in each row.

The briquette stove thus far has only a function of burning the briquettes inside the stove to warm the internal air due to its heat generation. And gas such as carbon monoxide generated during combustion is discharged to the outside through the communication. Accordingly, the conventional briquette stove mainly increases the temperature around the stove, and the temperature drops sharply as the distance from the stove increases. In other words, it is difficult to efficiently raise the overall temperature in a rather large space.

In some rural plastic houses, barns, eateries, and shops, heating means using diesel or banca C oil are used, but briquette stoves are still widely used. The present inventor has developed a briquette stove having a boiler structure capable of circulating hot water by modifying a conventional briquette stove so as to efficiently heat the briquette stove, and filed a patent application as a patent application No. 98-11054. (Filed March 30, 1998). However, in the invention of the patent application, it was impossible to change the briquettes once a day, and the briquettes of the uppermost layer did not completely burn, and the fire went out. In general, briquette stove can be used conveniently once a day to change the briquettes. Grinding briquettes more than once a day or in a shorter period than one day is not economical and very inconvenient because it requires a lot of manpower. In addition, the invention of the above patent application has found that the briquettes of the uppermost layer are not completely burned. That is, the fire went out when about 1/3 or 1/4 of the briquettes of the top layer remained.

Accordingly, the present inventors have solved the above drawbacks and have developed a stove of the present invention that can change briquettes once a day even if it is sufficiently burned, and all the briquettes of the uppermost layer can burn.

An object of the present invention is to provide a briquette stove that can maximize the thermal efficiency by circulating the heated hot water to the required place using the combustion heat generated from the briquette stove.

Another object of the present invention is to provide a briquette stove having a hot water boiler structure that can reduce fuel costs by maximizing thermal efficiency.

Another object of the present invention is to provide a briquette stove having a hot water boiler structure that can be easily installed in a plastic house, barn, shop, restaurant.

Still another object of the present invention is to provide a briquette stove having a hot water boiler structure that can change briquettes once a day.

Still another object of the present invention is to provide a briquette stove having a hot water boiler structure in which briquettes of the uppermost layer can be completely burned.

The above and other objects of the present invention can be achieved by the present invention described below.

1 is a perspective view schematically showing the appearance of a briquette stove having a hot water boiler structure according to the present invention. The briquette stove consists of an upper body 1, a lower body 2, a pedestal 3, a communication 4, and a double lid 5 and 6, as shown in FIG. Holes 11 and 12 are formed in the upper and lower body bodies 1 and 2 so that the connecting pipes 41 and 42 can be inserted respectively. The lower concave portion 15 is formed along the periphery.

2 is a plan view showing the interior of the briquette stove according to the present invention. The crucible 20 of the present invention is fixed inside the briquette stove. The external shape of the crucible 20 is the same as that of a conventional crucible, but a bending pipe 30 in which hot water is heated and circulated is embedded therein. FIG. 5 is a perspective view schematically showing the bending pipe 30, and FIG. 6 shows a crucible 20 in which a refractory material is molded outside the bending pipe.

Three circular spaces 21a, 21b, and 21c are formed in the crucible 20, each of which can accommodate 19 bullets. In each of the circular spaces, three 19-hole bullets are arranged in a three-layer structure. The bending pipe 30 inserted into the crucible 20 is preferably made of five layers having a triangular structure to be completely inserted into the crucible. Preferably, the overall length of the bending pipe 30 is maintained at about 6 m. In order to increase the efficiency of heat transfer, the bending pipe is preferably made of a copper tube. The structure of the bending pipe 30 has five layers, and the length of the bending pipe 30 should be about 6 m because the refractory material is appropriately contained between the pipe and the crucible 20 so as not to break.

3 is a schematic cross-sectional view of the briquette stove according to the present invention, Figure 4 is a schematic perspective view of the air blocking member 16 installed on the lower recess 15 of the briquette stove of the present invention. Conventional briquettes have a drawback in that the warmed air rises along the side passages 18 formed not only inside the crucible 20 but also outside the crucible, so that the briquettes of the uppermost layer do not burn completely. Therefore, the concave portion 15 is formed at the lower portion of the stove to prevent the air from rising along the side passage 18, and the air blocking member 16 is installed thereon. Since the crucible 20 is placed on the air blocking member 16, air does not rise along the side passage 18. In other words, air rises through the crucible 20 to burn briquettes. As a result, it is possible to completely burn the briquettes of the top layer, and it is enough to change the briquettes once a day. In the present invention, it is preferable that the upper case of the crucible and the upper case of the briquette stove maintain a gap of about 1 to 3 cm so that air is moved between the gaps so that the air burned out through the communication 4 is discharged. The upper end of the crucible should be designed about 5 to 15 cm higher than the briquette surface of the top layer, because the latent heat of the top of the crucible can completely burn the briquettes of the top layer. As shown in FIG. 4, the air blocking member 16 has a hole 17 in which briquettes can be inserted. The air blocking member 16 is preferably made of a casting having a thickness of about 2.5 to 3mm. Briquette stove of the present invention can control the air by the air conditioning means 19 installed in the lower portion like a conventional briquette stove.

The crucible 20 according to the invention is mounted inside the briquette stove, the threaded part 31 is located around the upper hole 11, and the threaded part 32 is located around the lower hole 12. The connecting pipes 41 and 42 are connected from the respective thread portions 31 and 32 so that the pipes can be connected to the outside. 7 is a schematic diagram of one embodiment of the present invention.

Threads are formed on the exterior of the threads 31 and 32 and valleys are formed on the interior of the connection pipes 41 and 42 so that they are screwed together and disassembled from each other. These connecting means must be firmly assembled so that the water circulated inside does not leak to the outside. This connecting means can be easily implemented by those skilled in the art to which this technology belongs.

The other end of the connecting pipes 41 and 42 has a fastening means to which the pipe 43 can be fastened. This fastening means can also be easily implemented by those skilled in the art to which this technology belongs.

At one position of the pipe 43, a water tank 50 for discharging air generated inside the pipe to the outside and replenishing insufficient water is installed, and a circulation pump 51 for circulating hot water in the pipe 43. ) Is installed. The circulation pump 51 may be preferably a pump used in a general boiler.

The water pumped by the circulation pump 51 flows into the lower portion of the bending pipe 30 located below the crucible 20 and moves along the bending pipe 30 to increase the temperature, and the upper portion of the bending pipe 30 and the connection pipe. Circulated through 41 and pipe 43.

The hot water circulated through the pipe 43 maintains a considerably high temperature and circulates heat through the pipe 43 surface. Therefore, extending the pipe 43 to the place where heat is required can raise the temperature while maintaining almost the same temperature. Usually, it is preferable that the length of the pipe 43 shall be 80-100 m or less. This length is a range that can be usefully used in vinyl houses, barns, restaurants, stores, and the like. The diameter of the pipe 43 is preferably about 20 to 30 mm.

The pipe 43 can be extended or shortened to suit the installation location of the stove and can be changed to suit the structure of the location. Such modifications or variations can be readily made by those skilled in the art. For example, when it is desired to heat the floor of a restaurant or a store, the pipe 43 may be installed inside the pipe 43 to be installed as a kind of boiler piping. The pipes can be appropriately arranged in a vinyl house or livestock house to maintain a relatively uniform indoor temperature.

In order to enhance the thermal efficiency of the briquetting stove of the present invention, the pipe 43 is more preferably copper pipe than stainless steel pipe, but stainless steel pipe may also be preferably used because it is expensive. In addition, it is preferable to use the corrugated pipe 60 which increases the surface area of the pipe as another method for improving the thermal efficiency. Corrugated pipe 60 can dissipate more heat because of its large surface area. 8 is a schematic perspective view of the corrugated pipe 60.

FIG. 9 is a perspective view schematically showing a stove to which covers 71 and 72 are attached to block carbon monoxide gas that may leak from the upper and lower holes 11 and 12. Covers 71 and 72 may be fastened by fastening means, such as bolts (not shown), and such methods may be readily implemented by those skilled in the art.

The present invention can maximize the thermal efficiency by circulating the heated hot water inside the pipe to the required place using the combustion heat generated from the coal briquettes, can reduce the fuel cost by maximizing the thermal efficiency, plastic house, barn, shops, restaurants It can be easily installed in the back, and can change the briquette once a day, and has the effect of providing a briquette stove having a hot water boiler structure capable of completely burning the briquettes of the top layer.

Simple modifications and variations of the present invention can be readily used by those skilled in the art, and all such variations or modifications can be considered to be included within the scope of the present invention.
