Description

[Detailed Description of the Invention] The present invention relates to a coal stove, and more particularly, to an improvement of a coal stove that ignites the upper side of coal placed in a combustion tube.

Among the well-known coal stoves, coal stoves that ignite the upper side of the coal put into the combustion tube often cause gas generated from the coal seam to blow out, or the smoke tube becomes clogged, requiring frequent cleaning. Nakatsuta. When we investigated the cause, we found that there was a problem with the amount of air intake into the combustion cylinder, and it is especially important to have a configuration that can appropriately adjust the amount of air intake during gas combustion after ignition. I learned something.

The present invention was created by focusing on such well-known technology, and includes a plurality of air holes on one side of the top plate of the lid.
Open a single air hole on the opposite side, place the lid on the combustion tube so that the multiple air holes are on the side of the combustion tube, and place the air intake on the combustion tube. The well-known structure of opening at the bottom of the cylinder wall is eliminated, and an air volume regulator with an air intake port is provided in the top plate and the vertical side wall so that it can be extracted. The purpose of the present invention is to provide a useful coal stove that can obtain an appropriate amount of air by operating the top plate and/or air volume regulator during gas combustion, thereby eliminating gas spouting and clogging of the chimney due to incomplete combustion. do.

To explain an example of the implementation with reference to the drawings, there are a plurality of lid bodies 1 placed on the combustion tube 8 (three in the illustrated example) on one side (on the right side in the drawing) of a straight line in the radial direction passing through the center.
The air holes 2 are drilled and arranged in the circumferential direction, and on the opposite side (left side in the drawing) there is a single air hole 3 (one in the drawing).
, and an appropriate number of through holes 14 are also drilled in the center. For the plurality of air holes 2, an open/close lid 6 with the same number of ventilation holes 4 is slidably provided, and the amount of air intake by the lid body 1 can be adjusted by sliding the open/close lid. At the same time, an opening/closing lid 7 having the same number of ventilation holes 5 is slidably attached to a single air hole 3, so that the amount of air intake can be adjusted in the same manner as described above. The lid body 1 is placed on the combustion tube 8 so that the plurality of air holes 2 are arranged on the side where the chimney stack is installed, and the air taken in from the bottom of the combustion tube 8 flows into the smoke tube 9.
It is possible to adjust the amount of air taken in from the lid body 1 with respect to the flow path toward the flow path, and to prevent disadvantages such as gas blowout and clogging of the smoke tube 9 due to incomplete combustion. And if necessary, a single air hole 3
The above-mentioned disadvantage is avoided by sliding the opening/closing lid 7 disposed on the lid body 1 and making it possible to adjust the amount of air taken in by the lid body 1 using the ventilation hole 5. The combustion tube 8 has a smoke tube 9 projecting horizontally from the upper side of the tube wall, and a rostol 13 is removably provided on the lower side of the inside, and coal c is put onto the rostle so that the coal c is ignited from above. Make it. Lostle 1 of combustion tube 8
An air volume regulator 10 is removably provided below point 3, but the regulator is installed on the lower side of the side opposite to the protruding side of the smoke tube 9, facing toward the side. It is configured so that the air taken in from the air amount regulator 10 can rise obliquely toward the smoke tube 9, and is configured so that it can come into good contact with the coal c. The air amount regulator 10 is constructed as a hollow box, and has an L-shaped air intake 11 in the top plate 1001 and an air intake 12 in the vertical side wall on both sides or one side. It consists of a combustion tube 8.
In contrast, it is inserted into the lower side of the rostre 13 so that it can be extracted, and arranged in an extractable manner so that the amount of air taken in from the lower side of the combustion tube 8 can be adjusted. L-shaped air intake 1
It is arranged in an extracting manner so that an appropriate amount of air can be taken in from the small opening 1101 on the front side of 1 to prevent gas blowout and clogging of the smoke tube 9 due to incomplete combustion. Note that the combustion tube 8 can be configured by connecting a heat radiation part (not shown) to the smoke tube 9.

Next, an experimental example using the coal stove with the above configuration will be described.

Coal c is fed into the combustion tube 8 in a small amount on the smoke tube 9 side, and 80% of the rest is injected, and during gas combustion, all the air holes 2 and 3 of the lid body 1 are opened, and the air amount regulator is 10 is the small opening 11 of the L-shaped air intake port 11
After extracting only 01 and letting air in, and leaving it for about 2 to 3 hours, a good gas combustion condition was obtained, no gas was ejected, and there was very little clogging of the smoke cylinder. I was able to go through almost a whole winter without cleaning it. We were then able to smoothly transition to surface combustion. The period during which the experiment was conducted was that the first one was in 1972.
For four months from December 1, 2016 to March 31, 1982,
The second time was for a four-month period from November 10, 1980 to March 16, 1980, and neither the first nor the second time required cleaning of the chimney during each period. The coal used was Horonai charcoal.

Since the present invention is constructed as described above, as is clear from the experimental examples, if all the air holes of the lid body and part of the air intake port of the air volume regulator are used during gas combustion, the coal seam can be removed from the coal seam. The amount of air necessary for the complete combustion of the generated gas is obtained, which has the effect of eliminating gas blow-outs and clogging of the chimney due to incomplete combustion. Moreover, the plurality of air holes drilled in the lid body are arranged on the side where the chimney stack is installed with respect to the combustion tube, and the air volume regulator is placed on the lower side of the roistle on the side opposite to the side where the smoke stack is installed with respect to the combustion tube. Therefore, the amount of air taken in from the plurality of air holes can be adjusted for the path through which the air taken in from the regulator flows toward the smoke cylinder, eliminating the fear of incomplete combustion, and eliminating the risk of incomplete combustion. This has the advantage of helping to prevent gas from blowing out and clogging of the smoke tube.
These effects have the advantage of eliminating the need for frequent cleaning of the chimney and avoiding the risk of gas blowout.

Therefore, the known technology can be significantly improved to achieve the intended purpose.
