Description

Solid fuel combustion device {APPARATUS FOR COMBUSTING SOLID FUEL}

The present invention relates to a combustion device, and to a combustion device that can be used for heating and other purposes by burning solid fuel such as firewood.

The boilers commonly used for heating are gas boilers using natural gas, liquefied petroleum gas, butane gas, oil boilers using kerosene, heavy oil, etc., briquette boilers using briquettes, etc. It can be divided into solid fuel boiler using firewood, lignite, and coal briquettes. Among these, gas boilers and oil boilers are widely used for their advantages such as ease of operation, management, fire control, and fuel supply and demand.

However, the price of oil or gas fluctuates all the time, especially when the oil price rises, there is a problem that the economic burden on the user. To avoid this burden, demand for alternative means, such as briquette boilers, increases during the oil price rise.

Briquette boilers have a relatively low fuel cost and relatively constant thermal power, compared to gas boilers and oil boilers. However, there is a risk of carbon monoxide poisoning and difficulty in treating residues after combustion. On the other hand, natural fuels such as coal fired or coal-based fuels such as lignite and coal briquettes, but solid fuels that do not require a formal combustion method such as briquettes, have a lower fuel cost than briquette boilers. High utilization in the region. For example, there is no economical choice to heat the interior of a crop plant, such as a firewood boiler, and the difficulty of supplying firewood is relatively small.

However, despite these advantages, boilers using solid fuels, especially firewood, have the following problems.

First, the combustion gas generated by burning firewood is harmful or unsuitable for the indoor environment and is discharged to the outside. At this time, since the heat discarded together with the discharged combustion gas is considerable, the boiler also shows low thermal efficiency.

Second, the time required for combustion is shorter than the heat inherent in the firewood. In other words, firewood generates maximum thermal power within a certain time when combustion starts, but the time for maintaining the maximum thermal power is relatively short, and the thermal power falls soon. If the thermal power drops, the other firewood needs to be re-burned to compensate for the insufficient thermal power, so that more firewood is consumed than necessary to achieve the desired level of heating effect, resulting in lower boiler thermal efficiency.

Third, it is not easy to control the fire power generated when burning firewood. This is because the firewood itself is non-standardized, and each calorie is also different, so that it is difficult to maintain the firepower precisely over a certain amount even if the user directly inputs the firewood at a constant speed.

Fourth, because other uses other than heating is not provided separately, the ease of use is inferior.

In addition, there are many problems. Despite the aforementioned advantages, there is a limit to the practical extension of the solid fuel boiler.

The present invention has been made to solve the above problems, an object of the present invention is to provide a solid fuel combustion device that can increase the thermal efficiency as a result of increasing the combustion time of solid fuel such as wood.

Another object of the present invention is to provide a solid fuel combustion device that can easily control the fire power while burning solid fuel.

It is another object of the present invention to provide a solid fuel combustion device that can serve both heating and cooking purposes.

Another object of the present invention is to provide a solid fuel combustion device that is easy to clean the inside.

Still another object of the present invention is to provide a solid fuel combustion device that can serve as a heating boiler by heating and supplying a heating medium.

And a heat dissipation tube and an exhaust pipe communicating with the second connection chamber to discharge the combustion gas to the outside. Here, it is preferable that at least one part of each upper surface is planar so that the said several heat radiating tubes may be used for cooking use easily. In addition, the plurality of heat dissipation tubes may be arranged in a double row to secure a wide flue. In addition, the plurality of heat dissipation pipes are preferably arranged to be substantially horizontal, respectively, in order to secure a time for the combustion gas to stay.

In the solid fuel combustion apparatus according to the present invention, it is preferable that at least one surface of each of the first connection chamber and the second connection chamber is detachably coupled.

In addition, in the solid fuel combustion apparatus according to the present invention, it is preferable that the combustion chamber is provided with an air control hole for adjusting the amount of air introduced into the combustion space.

In addition, in the solid fuel combustion apparatus according to the present invention, the first connection chamber and the second connection chamber respectively correspond to any one pair of heat dissipation tubes neighboring in the vertical direction among the plurality of heat dissipation tubes arranged in the plurality of layers. And a blocking plate disposed at a point to block up and down flow of the combustion gas, wherein each of the blocking plates of the first connection chamber and the second connection chamber is disposed at a height of each other. Here, the blocking plate has one end hinged to each of the first connection chamber or the second connection chamber, and coupled to the other end of the blocking plate to open and close the wire drawn out of the first connection chamber or the second connection chamber. It is preferable to further include. Alternatively, the first connection chamber or the second connection chamber may be formed with a slot for inserting the blocking plate, respectively, and the blocking plate may be slidably installed into the first connection chamber or the second connection chamber through the slot, respectively.

In addition, the solid fuel combustion apparatus according to the present invention is in contact with at least one of the combustion chamber, the first connection chamber, the second connection chamber, a plurality of heat dissipation tubes, the space for storing roasting food therein It may further include a formed roasting container.

According to the present invention, since a plurality of heat dissipation tubes communicating with the first connection chamber and the second connection chamber are arranged in a plurality of layers, the heat transfer area can be enlarged, and the flue length is longer than that of the exhaust pipe directly connected to the combustion chamber. The time can be extended, resulting in improved thermal efficiency. Furthermore, when the blocking plate is provided in each connection chamber, the effect of extending the year is maximized and the firepower can be controlled by adjusting the combustion time. In addition, since a plurality of heat dissipation tubes radiate high heat, the heat dissipation tube can be used for cooking, heating, and the like.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the solid fuel combustion apparatus according to the present invention.

1 is a perspective view of a first embodiment of a solid fuel combustion apparatus according to the present invention, Figure 2 is an exploded perspective view of the embodiment of Figure 1, Figure 3 is a cross-sectional view seen from the line A-A of FIG.

The combustion chamber 100 provides a combustion space 100a to receive and burn solid fuel therein. Solid fuel here includes wood, such as lignite, briquettes or charcoal. Combustion chamber 100 is not particularly limited in its shape, and may be a rectangular parallelepiped shape as shown in FIGS. 1 to 3, but may also be in another form such as a cylinder. The combustion space 100a is provided with a fuel injection door 110 on one side so as to be blocked from the outside as needed, the air control hole 111 is formed in the fuel injection door 110. In Figures 1 to 3, the fuel injection door 110 is shown as a sliding type, even if sliding, other types of solid fuel to selectively open the combustion chamber 100 to selectively enter the fuel into the combustion space (100a). It is enough if you can.

The first connection chamber 210 is disposed above the combustion chamber 100, and is disposed to be biased toward one end of the upper side of the combustion chamber 100 in consideration of a relative position with respect to the second connection chamber 220 which will be described later. The first connection chamber 210 has a space in which combustion gas passes, and the internal space communicates with the combustion space 100a of the combustion chamber 100. Similarly to the combustion chamber 100, the shape of the first connection chamber 210 is not particularly limited, but FIGS. 1 to 3 illustrate the rectangular parallelepiped shape for convenience. The first connection chamber 210 may be directly connected to the combustion chamber 100, but is preferably connected through the introduction pipe 300. The introduction pipe 300 allows to adjust the speed, that is, the flow rate per unit time, of the combustion gas generated in the combustion space 100a to enter the first connection chamber 210 according to its diameter.

The second connection chamber 220 also has a rectangular parallelepiped shape and is disposed above the combustion chamber 100, but is spaced apart from each other to face the first connection chamber 210. That is, when the combustion chamber 100 has a rectangular parallelepiped shape as shown in FIGS. 1 to 3, the first connection chamber 210 and the second connection chamber 220 are each in the long axial direction of the combustion chamber 100. It is arranged at both ends along the side facing each other.

The heat dissipation pipes 230, 240, and 250 are provided in plural, and communicate the first connection chamber 210 and the second connection chamber 220, respectively. In FIGS. 1 and 2, six heat dissipation tubes 230, 240, and 250 are illustrated, but the number may be increased or decreased as necessary. Although the number is different, it is preferable that the plurality of heat dissipation tubes 230, 240, 250 are arranged in a plurality of layers so as to have a height difference. In FIGS. 1 to 3, the first heat dissipation tube 230, the second heat dissipation tube 240, and the third heat dissipation tube are arranged. Each of the heat dissipation tubes 250 is provided as a pair, and is disposed at intervals in the vertical direction to form a three-layer structure. In addition, when the plurality of heat dissipation tubes are arranged only in a plurality of layers, problems may occur in the emission efficiency of the combustion gas. Therefore, it is preferable that the heat dissipation tubes are additionally arranged in a double row. For this reason, the six heat dissipation tubes 230, 240, and 250 of this embodiment form a two-column three-layer structure. In addition, it can be arranged in three rows of three layers of heat dissipation tube as needed, and the number of rows or layers can be adjusted according to the number of heat dissipation tubes, such as two rows of five layers of ten heat dissipation tubes. Of course.

On the other hand, each of the heat dissipation pipes 230, 240, and 250 is preferably part of the upper surface is flat. This is to facilitate the use of the upper surface of each of the heat dissipation tubes (230, 240, 250) as a cooking heating plate. That is, when food is directly placed on the upper surface of each of the heat dissipation tubes 230, 240, and 250, the food is cooked by the heat of the heat dissipation tubes 230, 240, and 250. At this time, each of the heat dissipation pipes 230, 240, 250 is arranged in a plurality of layers, and is arranged in the vertical direction, and thus the distance from the combustion chamber 100 is different. 3 may cause a difference in the temperature of each of the heat dissipation pipes 250. Therefore, it is possible to select and use a heat pipe having a temperature suitable for cooking, for example, a temperature suitable for a purpose such as baking, boiling, and warming. Of course, the top surface of each of the heat dissipation pipes 230, 240, 250 may be not only a part but a whole plane, or may have a tubular shape having a rectangular cross section as shown in FIGS. 1 to 3.

In addition, it is preferable that each of the heat dissipation pipes 230, 240, 250 is disposed substantially horizontally. This has the effect of slowing the flow rate of the combustion gas passing through each of the heat dissipation tubes 230, 240, 250, thereby reducing the amount of air flowing into the combustion chamber 100 per unit time. As a result, solid fuel, such as firewood, is burned at a slower rate in the combustion chamber 100.

The exhaust pipe 400 is disposed to communicate with the second connection chamber 220, and finally passes before the combustion gas generated in the combustion chamber 100 is exhausted to the outside, thereby making the flue from the combustion chamber 100 to the outside. (煙道) is completed.

Reference numeral 50 not described above is a spacer 50 inserted between the combustion chamber 100 and the second connection chamber 220, and corresponds to the height of the first combustion chamber 100 by the introduction pipe 300. By adjusting the height of the second connection chamber 220, and to minimize the transfer of heat directly from the combustion chamber 100 to the second connection chamber 220, it may be omitted in some cases.

Referring to FIG. 3, the use state of the embodiment of FIG. 1 will be described.

First, the fuel injection door 110 of the combustion chamber 100 is opened, and solid fuel such as a firewood is input into the combustion space 100a. In this case, the fuel support 120 having a mesh shape may be positioned in the combustion chamber 100 for smooth combustion and oxygen supply. The fuel support unit 120 supports the injected solid fuel, and may be variously modified and used according to the specific form of the solid fuel. For example, the lignite fuel supporter 120 has a smaller lattice spacing than the fuel supporter 120 for the firewood, and may have a shape in which a plurality of bars (parallel) are arranged in parallel according to the shape of the firewood. have.

Next, the injected solid fuel is ignited, and the fuel injection door 110 is closed. When the solid fuel starts to burn, the air adjusting hole 111 is adjusted to adjust the amount of air flowing into the combustion space 100a. The hot combustion gas generated as the solid fuel is burned moves along the path as shown by the arrows in FIG. 3. That is, the combustion gas enters the first connection chamber 210 through the introduction pipe 300, moves horizontally again through the heat dissipation pipes 230, 240, and 250 to reach the second connection chamber 220. In this process, the hot combustion gas is mainly heat exchanged with the outside air by the heat dissipation pipes 230, 240, and 250, thereby providing a heating effect in the space in which the present embodiment is disposed. Since a plurality of heat dissipation tubes 230, 240, and 250 are disposed, and in particular, the heat dissipation tubes 230, 240, and 250 are disposed substantially horizontally, it is possible to maximize the time for the high temperature combustion gas to stay inside the heat dissipation tubes 230, 240, and 250. The combustion gas reaching the second connection chamber 220 is finally discharged to the outside through the exhaust pipe 400. At this time, since the combustion gas passes a considerable heat while passing through the heat dissipation pipes 230, 240 and 250, the heat lost is minimized as compared with a conventional solid fuel boiler without a structure such as the heat dissipation pipes 230, 240 and 250.

On the other hand, it is also possible to consider a way to further secure the time that the high-temperature combustion gas stays inside the heat dissipation tubes (230, 240, 250). Figure 4 is a partially exploded perspective view showing a second embodiment of a solid fuel combustion apparatus according to the present invention, Figure 5 is a cross-sectional view seen from the line B-B of FIG.

4 illustrates a state in which one surface of the second connection chamber 220 is separated and removed in this embodiment. As described above, when one surface of the second connection chamber 220 is detachably installed, it is easy to clean the second connection chamber 220 or the inside of each of the heat dissipation tubes 230, 240, and 250. Similarly, one surface of the first connection chamber 210 may be detachably coupled.

The blocking plate 221 is installed in the second connection chamber 220. As shown in the cross-sectional view of FIG. 5, the blocking plate 221 functions to further narrow the flue gas flow and extend the length of the flue gas along with the blocking plate 211 provided in the first connection chamber 210. To this end, the blocking plate 211 of the first connection chamber 210 and the blocking plate 221 of the second connection chamber 220 each have a pair of heat radiating tubes neighboring in a vertical direction among the plurality of heat radiating tubes 230, 240, and 250. At the corresponding point in between, it blocks the up and down flow of the combustion gas, so as to be disposed in different layers, respectively. That is, the blocking plate 211 of the first connection chamber 210 is disposed at a point corresponding to between the second heat dissipation tube 240 and the third heat dissipation tube 250 and burns in the first connection chamber 210. The up and down flow of the gas is blocked, and as a result, the combustion gas entering through the introduction pipe 300 flows along the third heat dissipation pipe 250. On the other hand, the blocking plate 221 of the second connection chamber 220 is disposed at a point corresponding to between the first heat dissipation pipe 230 and the second heat dissipation pipe 240, so that combustion gas is discharged in the second connection chamber 220. It blocks the flow in the vertical direction, so that all the combustion gas entered along the third heat dissipation tube 250 enters the second heat dissipation tube 240. The combustion gas returned back to the first connection chamber 210 along the second heat dissipation tube 240 moves to the second connection chamber 220 along the first heat dissipation tube 230 and finally moves the exhaust pipe 400. Through the outside. Comparing the year of the present embodiment with the year of the previous embodiment, the cross-sectional area is reduced by approximately one third, while the length is approximately three times longer. Therefore, the time that the combustion gas stays in the plurality of heat dissipation pipes 230, 240, 250 is arithmetically increased by 9 times, and more heat exchange can be achieved. In addition, since the amount of air flowing into the combustion chamber 100 per unit time is also reduced, the solid fuel is induced to burn slowly over a longer time. This action can be auxiliary controlled by the operation of changing the size of the air control hole (111).

On the other hand, when the blocking plates 211 and 221 are provided, the third heat dissipation tube 250 is the highest temperature, the first heat dissipation tube 230 is the lowest temperature, the temperature difference of each of the heat dissipation tubes 230, 240, 250 is preceded It becomes larger than in the case of the embodiment. Therefore, the third heat dissipation tube 250 is used for cooking, such as roasting, the second heat dissipation tube 240 is used for warming water, and the first heat dissipation tube 230 is used for thawing. It can be maximized.

6 is a cross-sectional view of a third embodiment of a solid fuel combustion apparatus according to the present invention.

In this embodiment, the blocking plates 211 and 221 of the second embodiment are described in more detail. The blocking plate 211 installed in the first connection chamber 210 has one end thereof on the inner wall surface of the first connection chamber 210. It is hinged. The other end side of the blocking plate 211 is coupled to the opening and closing wire 215, the opening and closing wire 215 is extended to be drawn out of the first connection chamber 210.

In addition, a slot 220a is formed at one side of the second connection chamber 220, and the blocking plate 221 is inserted through the slot 220a to be slidably installed inside the second connection chamber 220. .

Each of the blocking plates 211 and 221 having such a configuration is installed in a so-called movable manner so as to allow a constant relative movement with respect to the first connecting chamber 210 or the second connecting chamber 220, and the two blocking plates 211 and 221 are common. The first connection chamber 210 or the second connection chamber 220 is operated to block or open or close the flue inside each. Therefore, if necessary, it can have an effect such as no blocking plate. For example, when the opening and closing wire 215 connected to the blocking plate 211 of the first connection chamber 210 is delayed and the blocking plate 211 is rotated as shown in FIG. 6, the combustion chamber 100 enters from the combustion chamber 100. One combustion gas may be partially passed to the third heat dissipation tube 250, and some may pass through the blocking plate 211 to the second heat dissipation tube 240 or the first heat dissipation tube 230. Likewise, when the blocking plate 221 of the second connection chamber 220 is pulled out so that the blocking plate 221 is exposed to the outside through the slot 220a, the third heat dissipation pipe 250 is opened. Most of the combustion gas entering the second connection chamber 220 through the exhaust pipe 400 immediately.

However, the main other reason for making each of the blocking plates 211 and 221 movable in this manner is to make it possible to easily remove foreign substances such as soot and ash deposited in the year. That is, the first connection chamber 210 and the second connection chamber 210 may be formed by the blocking plates 211 and 221, among the first connection chambers 210, the heat dissipation pipes 230, 240, 250, and the second connection chambers 220 constituting the flue. In 220, the flow direction of the combustion gas changes, so that deposition occurs in the portion where the flow direction changes. Such deposition of foreign matters should be removed because it hinders the flow of the combustion gas. At this time, the foreign matters deposited on the blocking plates 211 and 221 may be removed by operating the blocking plates 211 and 221. 220) to the bottom. Foreign matter gathered at the bottom of each connection chamber 210, 220 can be treated at a time in a state in which each connection chamber 210,220 is opened at a later time, thereby making maintenance easier.

In the above, the blocking plate 211 of the first connection chamber 210 is hinged, and the blocking plate 221 of the second connection chamber 220 is illustrated as being slide-coupled, but both may have different coupling methods. Naturally, both can be hinged or slide coupled.

This embodiment is characterized in that it further comprises a water jacket 500 and the roasting container (600).

The water jacket 500 includes a supply port 510 for receiving a heating medium from the outside, and an outlet 520 for discharging the heating medium to the outside, and a space for accommodating the heating medium is formed therein. have. Water jacket 500 may be provided in plurality, if necessary, where the combustion chamber 100, the first connection chamber 210, the second connection chamber 220, heat radiating tubes 230, 240, 250, etc. Even a close contact may be installed. In FIG. 7, two water jackets are installed on the outer side of the combustion chamber 100, one on each of the connection chambers 210 and 220 and the heat dissipation tubes 230, 240 and 250, but one of the two may be omitted. And may be divided into more numbers. As a heating medium, water or a mixed pressure liquid such as brine is used, which is mainly composed of water or water, as used in a conventional heating boiler.

The roasting container 600 has a space for accommodating food therein and is selectively installed outside the combustion chamber, each connection chamber, or the heat dissipation tube, like the water jacket 500. In FIG. 7, a pair is installed above the combustion chamber 100. The roasting container 600 is for easily baking things such as sweet potatoes or potatoes, and preferably includes a drawer 610 and a housing 620 for accommodating the drawer 610 to easily put or take out food. Do. Meanwhile, in FIG. 7, the roasting container 600 is illustrated as being installed in the combustion chamber 100 through the water jacket 500 on the lower side, but may be directly attached to the outer surface of the combustion chamber 100, and the heat dissipation pipes 230, 240, 250, or the like. It may be directly attached to the outside of the first connection chamber 210 or the second connection chamber 220. In this case, the shape of the water jacket 500 may be deformed such that the size of the water jacket 500 is reduced so as not to spatially interfere with the roasting container 600.
