[0031] Reference Figure 1 The utility model provides a kind of combustion equipment, including feed pipe 1, combustion round pipe 2, guide plate 31 and flow reducer 32, feed pipe 1 and combustion round pipe 2 bottom are interconnected and form combustion chamber 3, and transparent tube 22 is detachably installed at the top of combustion round pipe 2;Guide plate 31 is obliquely arranged in combustion chamber 3 to one side of combustion round pipe 2, and flow reducer 32 is arranged above guide plate 31 and is suitable for dispersing fuel on guide plate 31.

[0032] In the embodiment, flow reducer 32 is arranged above guide plate 31 of combustion chamber 3, which disperses fuel falling from guide plate 31, thereby reducing the falling speed of fuel, and preventing the flame from being extinguished due to rapid falling of fuel;At the same time, the cavity formed below flow reducer 32 can avoid fuel accumulation too dense, provide more sufficient combustion space for fuel, thereby improving combustion efficiency.

[0033] Specifically, the top of the feeding pipe 1 is provided with a feeding port, the top of the combustion round pipe 2 is provided with a flame outlet port, and the bottom of the feeding pipe 1 is communicated with the combustion round pipe 2. The combustion square pipe is changed into the combustion round pipe 2 in the application, and the combustion round pipe 2 is coaxially arranged with the transparent pipe 22, so that the flame of the combustion round pipe 2 entering the transparent pipe 22 is more uniform, the transparent pipe 22 is more uniformly heated, and the flame is avoided from being concentrated in the corner, thereby reducing the phenomenon of local overheating and uneven combustion. Moreover, the combustion characteristics of the combustion round pipe 2 are more stable, the stretching effect on the flame is weaker, the combustion process is more stable, the local high-temperature impact of flame fluctuation on the inner wall of the transparent pipe 22 is reduced, and black marks are not easy to be generated in the transparent pipe 22. However, compared with the combustion square pipe, the cross-sectional area of the combustion round pipe 2 is reduced, and fuel is more likely to gather at the communication position of the combustion round pipe 2 and the feeding pipe 1. The gathering of fuel will lead to uneven distribution of fuel in the combustion chamber 3, local fuel concentration is too high, and then oxygen supply in the combustion chamber 3 is relatively insufficient, thereby causing insufficient combustion. This phenomenon can cause the fuel to be unable to be completely combusted, produce carbon deposition and black smoke, and reduce the combustion efficiency. In addition, the fuel accumulation will also make the airflow distribution in the combustion chamber 3 disorderly, further affecting the combustion stability. Moreover, since the cross section of the connection position of the combustion round pipe 2 and the feeding pipe 1 is circular, after the fuel is accumulated at the communication position, the falling speed of the fuel is accelerated, and the fuel on the guide plate 31 will slide along the cross-sectional arc of the combustion round pipe 2 and collide with each other in the falling process, which is easy to directly impact the flame, thereby easily extinguishing the flame. Therefore, in order to avoid the fuel from sliding along the cross section of the combustion round pipe 2 and colliding with each other in the falling process and extinguishing the flame, the application is provided with the flow-reducing piece 32 on the guide plate 31. The flow-reducing piece 32 can disperse the fuel on the guide plate 31, reduce the falling speed of the fuel, and reduce the collision between the fuels, thereby avoiding the flame from being extinguished. At the same time, the flow-reducing piece 32 forms a cavity in the combustion chamber 3, which provides more sufficient combustion space and air for the fuel, prevents the fuel from being accumulated too densely, and thereby improves the combustion efficiency. The fuel in the application is preferably biomass particles, which is a renewable clean energy, and is usually a granular fuel made of agricultural and forestry waste through processes such as crushing, mixing, drying and extrusion. It is worth noting that the feeding pipe 1 is also detachably provided with a fuel expansion bin, which is communicated with the feeding pipe 1 and is suitable for supplementing fuel into the feeding pipe 1. At the same time, the top of the transparent pipe 22 is also provided with a spark catching net, which is fixed at the pipe opening of the transparent pipe 22 and has a cross section larger than that of the pipe opening of the transparent pipe 22, can catch sparks flying out of the pipe opening of the transparent pipe 22 after combustion, avoid sparks splashing, and improve safety performance. The specific structure of the spark catching net will not be described further.

[0034] More specifically, reference is made to Figure 2 and Figure 3The flow-reducing member 32 includes a flow-reducing rod 321 connected to the top of the combustion chamber 3 and extending axially along the combustion tube 2 above the guide plate 31. The flow-reducing rod 321 disperses the fuel on the guide plate 31, reducing the falling speed of the fuel and preventing the flame from being extinguished due to rapid falling. This dispersion also reduces the accumulation of fuel at the connection between the combustion tube 2 and the feed pipe 1, preventing excessive local fuel concentration. The flow-reducing rod 321 divides the combustion chamber 3 into upper and lower parts, with the lower part near the flow-reducing rod 321 forming a cavity. This cavity provides more space for fuel combustion, preventing overcrowding and improving combustion efficiency. The cavity also helps improve air flow in the combustion chamber 3, promoting fuel-air mixing. By dispersing the fuel and reducing its falling speed, the flow-reducing rod 321 reduces fuel collisions and prevents flame extinction. This design maintains flame stability during combustion, especially during fuel falling, reducing the risk of flame extinction. The flow-reducing rod 321 design helps distribute fuel more evenly, reducing local overheating and incomplete combustion. This not only improves combustion efficiency but also reduces carbon deposition and black smoke.

[0035] Preferably, a communication hole 21 is provided at the connection between the feed pipe 1 and the combustion tube 2, and the flow-reducing rod 321 is connected to the top of the communication hole 21 and extends axially along the combustion tube 2 into the feed pipe 1 above the guide plate 31.

[0036] In this embodiment, the flow-reducing rod 321 is arranged at the top of the connection between the combustion tube 2 and the feed pipe 1, and extends axially along the combustion tube 2, making it easier for the flame below the flow-reducing rod 321 to rise axially along the combustion tube 2 and the flow-reducing rod 321. This ensures uniform distribution of the flame in the transparent tube 22 and improves flame stability.

[0037] Specifically, the axial extension design of the flow-reducing rod 321 can guide the airflow to flow along the axial direction of the combustion circular tube 2, so that the airflow rising along the axial direction of the combustion circular tube 2 is more evenly distributed in the transparent tube 22. This design helps to stabilize the flame and reduce the flame fluctuation caused by airflow turbulence, that is, the flow-reducing rod 321 can optimize the airflow structure, effectively suppress the thermal-acoustic oscillation in the combustion process, improve the stability of the combustion chamber 3 under different working conditions, and improve the flame stability. Moreover, through the guiding action of the flow-reducing rod 321, the airflow is more evenly distributed in the combustion circular tube 2 and the transparent tube 22, and the flame can stably rise along the axial direction of the combustion circular tube 2, avoiding insufficient combustion caused by fuel accumulation or uneven airflow. The axially extending flow-reducing rod 321 can optimize the combustion process and reduce the local residence time of the high-temperature area below the flow-reducing rod 321, thereby reducing the generation of nitrogen oxides. It is worth noting that the flow-reducing rod 321 is connected above the guide plate 31 and extends upward into the combustion circular tube 2. The flow-reducing rod 321 can be connected to the inner side wall of the combustion circular tube 2, or to the top of the guide plate 31 or the feed pipe 1, or even to the combustion circular tube 2, the guide plate 31 and the feed pipe 1 at the same time. It is worth noting that a plurality of air inlet holes and air supplement holes are also provided on the side wall of the combustion circular tube 2, and the specific positions thereof are not limited further in the present application.

[0038] Preferably, the end of the flow-reducing rod 321 is located at the central position of the guide plate 31. In the present embodiment, the end of the flow-reducing rod 321 is located at the central position of the guide plate 31, which can effectively disperse the fuel from the center of the guide plate 31, avoid the accumulation of fuel at the edge of the guide plate 31 or the communication part between the combustion circular tube 2 and the feed pipe 1, and make the fuel more evenly distributed when entering the combustion chamber 3, thereby reducing the insufficient combustion caused by excessive local fuel concentration. The design of locating the end of the flow-reducing rod 321 at the central position can form a more stable flame shape, reduce the risk of flame fluctuation and extinction, and help the flame to stably rise along the axial direction of the combustion circular tube 2, thereby improving the overall performance of the combustion chamber 3.

[0039] In a transformed embodiment, the flow-reducing member 32 comprises a flow-reducing frame, and the shape of the flow-reducing frame is any one of an eight-shaped type, a cross-shaped type, a polygonal type, or a spiral type.

[0040] In this embodiment, the flow-reducing frame can achieve diversified fuel dispersion effects according to the specific needs of the combustion chamber 3 and the fuel characteristics. Specifically, various shapes of flow-reducing frames can be selected and optimized according to different fuel types (such as biomass particles, firewood, etc.) and combustion conditions, improving the versatility and adaptability of the combustion chamber 3. Among them, the eight-shaped flow-reducing frame can guide the fuel to both sides, reducing the accumulation of fuel in the center while maintaining a certain downward speed. The cross-shaped flow-reducing frame can uniformly disperse the fuel to four directions, further reducing the risk of concentrated fuel falling and increasing the contact area between the fuel and the air. The multi-edge flow-reducing frame can more evenly disperse the fuel through the polygonal structure, reducing the phenomenon of excessive local fuel concentration. The spiral-shaped flow-reducing frame can guide the fuel to fall along the spiral path, prolonging the residence time of the fuel in the combustion chamber 3, promoting the sufficient mixing of fuel and air, and improving the combustion efficiency. The irregular-shaped flow-reducing frame can be customized according to the specific working conditions of the combustion chamber 3, and the distribution and flow path of the fuel can be flexibly adjusted. Through diversified flow-reducing frame design, the distribution of fuel in the combustion chamber 3 is more uniform, and the combustion process is more stable, thereby improving the combustion efficiency and reducing fuel waste. In the deformation embodiment, the flow-reducing piece 32 can also include a flow-reducing rod 321 and a flow-reducing ring, and the flow-reducing rod 321 is arranged above the guide plate 31. It is worth noting that the flow-reducing piece 32 has various shapes, which can be selected and optimized according to the combustion conditions, and this application will not be further limited.

[0041] In another embodiment, the flow-reducing piece 32 includes a flow-reducing plate, and the flow-reducing plate is provided with a plurality of through holes, and the fuel in the feeding pipe 1 is adapted to pass through the through holes.

[0042] In this embodiment, the through holes on the flow-reducing plate can change the concentrated downward falling of the fuel into dispersed falling, avoiding the accumulation of fuel at the communication between the combustion circular pipe 2 and the feeding pipe 1; and after passing through the through holes, the fuel can be more evenly distributed in the combustion chamber 3, reducing the problem of excessive local fuel concentration, thereby improving the combustion efficiency.

[0043] Specifically, the position angle of the flow-reducing plate is not further limited by this application. It can be perpendicular to the guide plate 31, or it can be arranged along the axial direction of the combustion circular pipe 2. As long as it can communicate the upper and lower parts of the flow-reducing plate through the through holes, so that the fuel can better mix with the air in the combustion chamber 3 after passing through the through holes, promoting the complete combustion of the fuel and reducing the generation of carbon and pollutants; at this time, the combustion process is more stable, the flame is not easy to be extinguished, and the risk of extinguishing during the combustion process is reduced. Moreover, the design structure of the through holes of the flow-reducing plate is simple, easy to process and install, and reduces the manufacturing cost of the equipment. By adjusting the size, number and distribution of the through holes, the combustion effect can be flexibly optimized to adapt to different fuel types and combustion conditions.

[0044] Further, reference is made to Figure 3 andFigure 4 The guide plate 31 is also provided with a plurality of first air inlet holes 311, so that an air inlet chamber 11 is formed below the guide plate 31, and the top of the air inlet chamber 11 is also provided with second air inlet holes 111. The air inlet chamber 11 is inclined away from the feeding pipe 1, so that the air inlet chamber 11 is inclined downward relative to the horizontal line, and the air inlet chamber 11 is also provided with an ash collecting device 12 adapted to collect the ash below the guide plate 31.

[0045] In this embodiment, by inclining the air inlet chamber 11 away from the feeding pipe 1, the air supply and ash treatment of the combustion chamber 3 are further optimized. Specifically, the first air inlet holes 311 on the guide plate 31 and the second air inlet holes 111 on the top of the air inlet chamber 11 form a multi-stage air inlet system. Preferably, the combustion circular pipe 2 is also provided with air inlet channels. This design can provide more sufficient oxygen for the combustion chamber 3, ensure that the fuel has enough air support during the combustion process, and thus improve the combustion efficiency. The arrangement of the first air inlet holes 311 and the second air inlet holes 111 allows air to enter the combustion chamber 3 from multiple directions, further optimizing the mixing of air and fuel and reducing the problem of incomplete combustion. The air inlet chamber 11 is inclined away from the feeding pipe 1 and inclined downward relative to the horizontal line, which can guide the air in the air inlet chamber 11 to flow in a specific direction, forming a more stable airflow, avoiding direct impact of air on fuel, reducing the influence of airflow turbulence on the flame, thereby reducing the risk of fuel extinguishing and further improving the stability of combustion. The ash collecting device 12 arranged in the air inlet chamber 11 can effectively collect the ash generated by the guide plate 31, and the design of the ash collecting device 12 makes it easier to clean the ash, reducing the maintenance cost and time of the equipment. The ash collecting device 12 is inclined like the air inlet chamber 11, and the ash falling downward is automatically collected by the ash collecting device 12, so that the ash accumulates at the bottom of the air inlet chamber 11, ensuring that the top of the air inlet chamber 11 forms an air inlet passage, the combustion in the combustion chamber 3 is more complete, the interference of ash on the combustion process is reduced, and the erosion of the wall of the combustion chamber 3 and the transparent pipe 22 by the ash is also avoided, prolonging the service life of the equipment. It is worth noting that the air inlet chamber 11 of the present application is composed of an air inlet pipe and the space below the guide plate 31, the air inlet pipe is inclined downward relative to the horizontal line, and the ash collecting device 12 is arranged in the air inlet pipe. It is worth noting that the ash collecting device 12 is also provided with a plurality of air doors, through which the size of the fire can be adjusted to promote the combustion of the fuel in the combustion chamber 3.

[0046] Further, referring to Figure 5Further comprising a support assembly 4, the support assembly 4 is adapted to set the feed pipe 1 and the combustion round pipe 2 at an angle, so that the combustion round pipe 2 and the flow-reducing rod 321 are both set vertically. In this embodiment, by setting the feed pipe 1 and the combustion round pipe 2 at an angle, and further setting the guide plate 31 to one side of the combustion round pipe 2, the fuel can more smoothly fall along the guide plate 31 to the lower side of the combustion round pipe 2 during the falling process of the feed pipe 1, and the vertically set combustion round pipe 2 and the flow-reducing rod 321 can guide the fuel to be evenly distributed along the flow-reducing rod 321, further optimizing the falling path of the fuel and improving the combustion efficiency. Moreover, the vertically set combustion round pipe 2 is less likely to be tilted, the flame stably rises along the axial direction of the combustion round pipe 2, reducing the direct impact of the airflow on the flame, reducing the flame fluctuation, avoiding the flame being extinguished due to airflow turbulence, and improving the stability of the combustion. It should be noted that the specific support structure of the support assembly 4 is various, and the present application will not be further described here.

[0047] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
