[0001] APPARATUS FOR BURNING PERFECTLY BRIQUETTE [0002]

The present invention relates to a complete combustion apparatus for briquetting, and more particularly, to an apparatus for completely burning a briquette, and more particularly, to an apparatus for completely burning a briquette, The briquetting device is provided with a briquetting device for briquetting the briquettes. The briquetting device is provided with a briquetting device for briquetting the briquettes. To a complete combustion device of briquette capable of precisely predicting the replacement time of the briquettes.

Generally, briquettes are heat energy sources in which a plurality of air holes are vertically downwardly opened, such as 19 grit, 22 grit and 25 grit, and they are used mainly for heating such as a hearth or a boiler.

However, the heating equipment using the above-mentioned briquette was pushed to the heating equipment using alternative energy sources such as electricity, oil and gas, and the demand was decreased. However, due to the recent high oil prices and the low price of the briquette, Demand is increasing in animal breeding grounds, human labor stations and factories.

As an example, a conventional briquetting boiler, which is a kind of heating equipment using briquette as a raw material, will be described with reference to Fig.

As shown in FIG. 1, the conventional briquet boiler includes an oven 10 in which the briquettes 2 are accommodated, an inner case 11 in which the oven is installed, An outer case 13 forming an outer appearance of the briquetting boiler so as to form a space 12 between the outer case and the inner case 11 A ventilating hole 15 penetrating through the outer case 13 to open and close the briquette to the center of the briquette so that the briquettes can be dewatered by the air baffle 14, And a lid 16 for controlling the generated heat energy source so as not to leak to the outside.

However, most of the conventional briquetting combustion apparatuses such as the above-described conventional briquetting boilers have a vent hole for supplying air to briquettes aligned with the center of the briquette, and a lid is provided only on the upper part of the outer case, The center of the bar and briquettes can be completely burned by burning, but the outer edge of the briquettes is burned incompletely due to incomplete burning, resulting in a large amount of briquette gas such as carbon monoxide (CO) and at the same time, There is a problem.

In addition, since the burning rate and the thermal power of the briquettes must be controlled by adjusting the air switches according to the external temperature, such as during the winter, when the weather is severely fluctuated, if the air blower is opened too much, The briquette replacement time is also accelerated. If the air switch is slightly opened, the burning speed of the briquette is delayed, so that the replacement time of the briquette is delayed. However, there is a problem that the briquette is turned off or the thermal power is weak and incomplete burning occurs. That is, it is difficult to accurately predict the replacement time of the briquette.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a briquette combustion apparatus which not only covers an outer cover of an outer case of a briquetting combustion apparatus such as a briquetting furnace and a briquetting boiler, The briquettes in the center of the briquettes are spread near the outer edge of the briquettes so that the briquettes are completely burnt not only the center but also the outer edge of the briquettes, thereby minimizing the generation of carbon monoxide and other unnecessary consumption of briquette. And to provide a complete combustion device of briquette which can be used.

As shown in Figs. 7 to 11, the complete combustion apparatus for briquetting according to the second embodiment of the present invention includes two or three briquettes vertically stacked vertically and horizontally A briquetting furnace or briquetting boiler capable of storing a plurality of briquettes (101); An outer case 120 enclosing the furnace 110 while enclosing a space 115 between the furnace 110 and the furnace 110; A pedestal 130 for supplying or blocking air to or from the furnace 110 by opening or closing the vent 131 through the open / close switch 135 while supporting the furnace 110 and the outer case 120 from below; An inner cover 140 placed on the furnace 110 to cover the briquettes 101 with a predetermined interval; A cradle 150 coupled to an upper end of the outer case 120 to cover the outer case 120; And an outer cover 160 mounted on the cradle 150 to cover the inner cover 140 and a communication 170 communicating with the intermediate portion of the outer case 120 to communicate with the space 115. [ .

That is, the complete combustion apparatus for briquetting according to the second embodiment of the present invention is a structure for vertically stacking briquettes in one column or two columns, and includes elements similar to those of the first embodiment described above. Hereinafter, The description overlapping with the embodiment will be omitted and only different points will be described.

In the first embodiment described above, it is preferable that the furnace 110 is configured in a triangular shape because the furnace 110 is stacked and housed in three rows of the briquettes 101. In the second embodiment, however, The outer case 120 may be formed in a shape of a cylinder or a double cylinder ('oo'). Therefore, in the first embodiment, But it is preferable that the second embodiment is configured to have a rectangular shape.

For example, as shown in FIG. 10, in the stove burning in two rows, the left inner furnace 110 is not covered with the inner lid 140, the right furnace is covered with the inner lid 140, As shown in FIG. 11, the briquettes on the left side are well burned only in the center portion and the outer edges are not burned well, so that the thermal power is weak. On the other hand, And the outer edge of the briquette as well as the center of the briquette is well burned, so that the thermal power is very strong.

In addition, as well as the central portion and the outer edge of the briquetting vessel 101 are burnt through the inner lid 140 as described above and the excellent thermal power is maintained, the bare-mouth switch 135 installed at the lower portion of the briquetting combustion apparatus is adjusted When the communication is closed by 1/3 to 1/2 through the communication valve 171, the combustion is continued for 24 hours to 30 hours while the thermal power of the briquetting is maintained as it was before closing the communication hole 131 So that the replacement time can be accurately predicted.

On the other hand, the solar industry, which is a business place of the present applicant, has been proposed by NOW Environmental Industries Co., Ltd., as shown in Figs. 12 and 13, to generate heat from a combustion apparatus having an inner cover according to the first and second embodiments The amount of carbon monoxide and the amount of carbon monoxide in a conventional conventional briquetting furnace without an inner lid were measured and compared.
