The present invention relates to a side-burning coal stove. Conventional coal-fired stoves are up-burning, so a coal supply device must be installed around the stalker, and the tanks must be attached separately, which increases the volume, whereas the scale of the flue-gases is caused by dust generated during coal combustion. Due to the simplification of the flue gas furnace, the residence time of the combustion gas was short, the area of the stove itself, which generates the heat of combustion and the heat of the exhaust gas, and the heat loss due to the communication were high, resulting in poor heating efficiency.

The present invention has been devised to solve such a conventional closed end, and since the barrel is located directly on the top of the rostol by using the combustion method as the lateral combustion type, a separate carbon supply device is not required, and the residence time of the combustion gas is long. By constructing a flue gas furnace, it is possible to efficiently use exhaust gas heat, and the heating area of the stove itself becomes large, maximizing heating efficiency. It is possible to maintain a good combustion state at all times.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The upper, middle, and lower flue gas passages 3a, 3b, and 3c connected in a zigzag form are connected to the combustion chamber 2 at the bottom of the barrel 1 through the lateral air supply 4, so that one end of the lower flue fuel 3c is connected. Is connected to one side of the barrel (1). In the combustion chamber 2, a plurality of variable spheres 5c are lost between side edges 5a and 5b inclined toward the lower side flue gas path 3c and are connected to each other by links 5 '. Is provided, and the link 5 'is supported by the actuating levers 7 and 8 with the movable shaft 9 and the upper end of the supporting rod 6 of the supporting rod 6, which is adhered to the left and right side walls in the combustion chamber 2. Is connected to ').

One end of the movable shaft 9 is configured to be connected to the handle lever 10 to the outside of the combustion chamber 2.

Unexplained reference numeral 11 is a return container, 12 is a heat shield board, 13 is a subsection, and 14 is a communication.

According to the present invention configured as described above, the combustion of coal in the combustion chamber 2 or the removal of the ash ash is made according to the position operation of the variable sphere 5c in the combustion stole 5, and the handle lever 10 as shown in FIG. When the movable shaft 9 is rotated in one direction by lifting upward), the actuating lever 7 moves the link 5 'to which the plurality of variable spheres 5c are connected, and the inclined fixed side in the combustion chamber 2 The plurality of variable spheres 5c held at 5a and 5b are rotated in one direction to maintain a horizontal state.

Therefore, the air through the air supply port 4 formed on the side surface of the barrel 1 flows into the gaps of the variable spheres 5c to promote the combustion of coal in the combustion chamber 2, and at the same time to the link 5 '. As the associated operating lever 8 is also moved upward, the supporting rod 6 'of the supporting rod stall 6 is rotated toward the combustion roaster 5 around the upper coalescing portion, and the combustion furnace To close the gap between the stall (5) and the support rostol (6). Prevents coal from accumulating on the lower flue gas furnace 3c. Therefore, as the coal is burned on the combustion stole 5 in the combustion chamber 2, the heat of combustion and the combustion gas flow back toward the communication 14 and the lower flue gas 3c, the central flue gas 3b, and the upper flue gas 3a. Thus, as each flue gas furnace is heated by combustion heat and combustion gas to generate heat to the outside, the heat generating area becomes large, and the heating effect is very good. When the coal on the combustion roast 5 burns down, as shown in FIG. 3, the handle lever 10 is lowered to rotate the movable shaft 9 in the opposite direction. At this time, the actuating lever 7 moves the link 5 'downward, and the link 5' moves the actuating lever 8 downward so that the plurality of variable spheres 5c are centered on the side portions 5a and 5b. While standing in a vertical state while being rotated oppositely, the supporting rod 6 is rotated toward the lower flue gas furnace 3c centered on the upper coalescing portion while the support 6 'is pushed, and the carbonaceous material has a gap between the variable spheres 5c. And a fall back to the bottom receiving cylinder 11 between the combustion roast 5 and the supporting roast 6.

In this way, after removing the ash, the handle lever 10 is lifted up as shown in FIG. 2 and the variable mouths 5c are kept in a horizontal state. The coal in the barrel 1 is burned on the combustion coal on the combustion rostol 5 by its own weight. The combustion continues to build up.

The heat shield plate 12 prevents heat to the side walls of the upper and middle flue gas passages 3a and 3b from being transferred to the barrel 1, thereby preventing the coal in the barrel 1 from generating gas due to heat. When the scale is pinched by dust or the like on the flue gas passages 3a, 3b and 3c, the cleaning tool 13 provided on the side of the lower flue gas passage 3c is opened and removed.

As described above, the present invention can maximize the heating efficiency due to the long residence time of the combustion heat and the gas, and can simultaneously remove the charcoal and charcoal by simple operation of the lever to maintain a good combustion state at all times.
