[0024] The specific embodiment is only the explanation of the utility model, and it is not the limitation of the utility model, and the person skilled in the art can make the modification without the creative contribution according to the need after reading the present specification, but as long as it is in the right claim range of the utility model, it is protected by the patent law.
[0025] Example 1: This example relates to a combustion chamber 100 used in a combustion furnace, such as... Figure 1 As shown, the system includes a combustion exhaust body 110 and a plurality of ventilation holes 120 disposed on the combustion exhaust body 110. The combustion exhaust body 110 has a central portion a, a middle section b, and a peripheral portion c. In this embodiment, the central portion a is flat, and the peripheral portion c is a gentle slope. Flat means parallel to the bottom surface, while a gentle slope is a slope with a slight angle. In some embodiments, the central portion a may also be a gentle slope; in some embodiments, the peripheral portion c may also be flat.
[0026] The middle section b is higher than the central section a and the peripheral section c. There are slopes between the middle section b and the central section a, and between the middle section b and the peripheral section c. Therefore, when fuels such as wood strips or coal are placed, one end can overlap the middle section b, and the other end can overlap the peripheral section c. This ensures that the multiple ventilation holes 120 located at the central section a are not blocked by fuel, allowing sufficient air to enter. This prevents the fuel placed on it from easily extinguishing, thus reducing or even eliminating the need for user management, allowing the fuel to burn continuously.
[0027] In this embodiment, the transitions between the middle section b and the central section a, and between the middle section b and the peripheral section c, are all curved surfaces. Therefore, when fuels such as wood strips or coal are placed, the middle section of the fuel is suspended in the air, and the multiple ventilation holes 120 located below the middle section of the fuel are not completely blocked by the fuel, allowing sufficient air to enter. This further makes the fuel placed on it less likely to extinguish, thus reducing or even eliminating the need for user management, allowing the fuel to burn continuously.
[0028] Preferably, the angle between the middle section b and the peripheral section c is 110°-160°. In this embodiment, the angle between the middle section b and the peripheral section c is approximately 150°.
[0029] In this embodiment, the exhaust body 110 is rectangular, and the four corners of the exhaust body 110 are rounded. In some embodiments, the exhaust body 110 is circular.
[0030] In this embodiment, the central portion a of the combustion chamber body 110 is circular and can be used to place igniting materials, such as a ignition ring. The ignition ring is used to heat fuels such as wood strips and coal, so that the fuels can burn. The fuel is mounted on the periphery of the central portion a of the combustion chamber body 110, enabling 360° combustion and making the combustion in the combustion furnace more uniform.
[0031] In this embodiment, the ventilation holes 120 are circular, and the plurality of ventilation holes 120 are arranged in a matrix. In some embodiments, the ventilation holes 120 may also be elliptical or elongated; in some embodiments, the plurality of ventilation holes 120 may also be arranged in a circumferential pattern.
[0032] In this embodiment, the combustion row body is in a sheet shape, and the thicknesses of the central portion a, the middle portion b, and the peripheral portion c of the combustion row body 110 are substantially uniform.
[0033] Preferably, the peripheral portion c is provided with a reinforcing rib 130. In this embodiment, one reinforcing rib 130 is arranged around the peripheral portion c. By arranging the reinforcing rib 130, the overall strength of the combustion row 100 is enhanced, so that the combustion row 100 will not be deformed due to high temperature when used in the combustion furnace.
[0034] Embodiment II: This embodiment relates to a combustion row 100 for a combustion furnace, such as Figure 2 As shown, the combustion row 100 comprises a combustion row body 110 and a plurality of ventilation holes 120 arranged on the combustion row body 110. The combustion row body 110 has a raised portion d, a central portion a, a middle portion b, and a peripheral portion c. The raised portion d is arranged in the center of the central portion a, and the raised portion d is higher than the middle portion b. The raised portion d of the combustion row body 110 can be used to accommodate a fire starting material, such as a fire ring. The fire ring is used to heat fuel such as wood sticks or coal, so that the fuel such as wood sticks or coal can be burned. The fuel is arranged around the fire ring, and can be burned in 360 degrees, so that the combustion in the combustion furnace is more uniform.
[0035] In this embodiment, the central portion a is flat, and the peripheral portion c is also flat. In some embodiments, the central portion a and the peripheral portion c can also be flat slopes.
[0036] The middle portion b is higher than the central portion a and the peripheral portion c. The middle portion b and the central portion a, and the middle portion b and the peripheral portion c have slopes therebetween.
[0037] Therefore, when the fuel such as wood sticks or coal is placed, one end of the fuel can be overlapped on the middle portion b, and the other end of the fuel can be overlapped on the peripheral portion c. Therefore, the plurality of ventilation holes 120 located in the central portion a are not blocked by the fuel, and sufficient air can enter, so that the fuel placed thereon is not easily extinguished, and the user can reduce or even eliminate the management, and the fuel can be burned all the time.
[0038] In this embodiment, the middle portion b and the central portion a, and the middle portion b and the peripheral portion c are curved surfaces. Therefore, when the fuel such as wood sticks or coal is placed, the middle portion of the fuel is suspended, and the plurality of ventilation holes 120 located below the middle portion of the fuel are not completely blocked by the fuel, and sufficient air can also enter, so that the fuel placed thereon is not easily extinguished, and the user can reduce or even eliminate the management, and the fuel can be burned all the time.
[0039] Preferably, the angle between the middle portion b and the peripheral portion c is 110°-160°. In this embodiment, the angle between the middle portion b and the peripheral portion c is about 135°.
[0040] In the embodiment, the combustion row body 110 is rectangular, and the four corners of the combustion row body 110 are rounded.
[0041] In the embodiment, the central part a of the combustion row body 110 is annular and surrounds the circumferential side of the protruding part d.
[0042] In the embodiment, the ventilation holes 120 are circular, and the plurality of ventilation holes 120 are circumferentially distributed. In some embodiments, the ventilation holes 120 can also be elliptical or strip-shaped; in some embodiments, the plurality of ventilation holes 120 can also be circumferentially distributed in a matrix.
[0043] In the embodiment, the combustion row body 110 is annular, and the thicknesses of the protruding part d, the central part a, the middle part b, and the peripheral part c are substantially uniform.
[0044] Preferably, the peripheral part c is provided with a reinforcing rib 130. Specifically, in the embodiment, one reinforcing rib 130 is arranged around the peripheral part c. By arranging the reinforcing rib 130, the overall strength of the combustion row 100 is enhanced, so that the combustion row 100 will not deform due to high temperature when used in the combustion furnace.
[0045] Embodiment three: the embodiment relates to a combustion furnace, as shown in the figure, comprising: a combustion furnace body 200 and a combustion row 100 arranged in the combustion furnace body 200. The combustion row 100 is the combustion row 100 described in embodiment one or embodiment two. Figure 3
[0046] The working principle of the utility model is roughly as follows: by designing the combustion row body 110 to be higher at the middle part b than at the central part a and the peripheral part c, and arranging a slope between the middle part b and the peripheral part c, the fuel such as wood strips and coal can be overlapped at one end on the middle part b and at the other end on the peripheral part c, the plurality of ventilation holes 120 at the central part a are not blocked by the fuel, sufficient air can enter, the fuel placed thereon is not easy to be extinguished, and thus the user management is reduced or even not needed, and the fuel can be burned all the time.
