Since the exhaust section 7 is located at the top of the end of the combustion chamber near the coal inlet, the high-temperature flue gas generated by combustion can fill the combustion chamber before being discharged, increasing the temperature in the combustion chamber and helping to improve the heating efficiency; by setting a first smoke guide cavity at the top of the end of the combustion chamber away from the exhaust section and a second smoke guide cavity at the top of the end of the combustion chamber near the exhaust section, and then using the smoke guide assembly to guide the exhaust section... The first and second flue gas guiding chambers are connected, increasing the length of the high-temperature flue gas transport path within the furnace. This allows the flue gas to fully react within the furnace before being discharged, improving the thermal efficiency of the flue gas while reducing pollutant emissions. Furthermore, by increasing the flue gas transport path within the furnace, the height of the external flue can be reduced, stabilizing the furnace temperature. By placing the flue gas guiding assembly within the water jacket cavity, the high-temperature flue gas transported through the assembly can further heat the water within the water jacket cavity, improving heating efficiency. Additionally, the heat exchange between the high-temperature flue gas and water lowers the flue gas temperature, reducing nitrogen oxide production and thus reducing pollutant emissions.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] Please refer to Figures 1-8 This application provides a horizontal combustion small heating stove, comprising:

[0039] The furnace body has a coal inlet 3 at one end and a smoke outlet 4 at the top.

[0040] Combustion chamber 6 is located inside the furnace body and extends in a direction parallel to the bottom surface of the furnace body. One end of the combustion chamber 6 is connected to the coal inlet 3. The top of the end of the combustion chamber 6 near the coal inlet 3 is provided with a flue gas section 7 that is connected to the combustion chamber 6.

[0041] Water jacket cavity 8, which is located on the outer periphery of combustion chamber 6, is used for filling with water;

[0042] The first smoke guide chamber 9 is located above the end of the combustion chamber 6 away from the coal inlet 3, and the first smoke guide chamber 9 is connected to the combustion chamber 6 through the smoke exhaust section 7;

[0043] The second smoke guiding chamber 10 is located above the smoke exhaust section 7 and is connected to the smoke outlet 4.

[0044] A smoke guiding assembly is disposed within the water jacket cavity 8. The smoke guiding assembly connects the smoke exhaust section 7 and the first smoke guiding cavity 9, and also connects the first smoke guiding cavity 9 and the second smoke guiding cavity 10.

[0045] Specifically, in this embodiment, the furnace body has a rectangular structure. A coal inlet 3 is provided on one end of a side wall parallel to the length direction of the furnace body, near the side wall. The coal inlet 3 is used to fill coal, and a cover that can be opened and closed is provided at the coal inlet 3 to close the coal inlet 3. A smoke outlet 4 is provided on the top wall of the furnace body near the end of the coal inlet 3. The smoke outlet 4 is used to connect the furnace body to an external flue to discharge flue gas. The combustion chamber 6 is located at the bottom of the furnace body and extends along the length direction of the furnace body. The side of the combustion chamber 6 near the coal inlet 3 is connected to the coal inlet 3, that is, coal is added from the side position of one end of the combustion chamber 6. The combustion chamber 6 is lengthened in the furnace body. The lengthened combustion chamber 6 can ensure stable combustion of the stove for a long time and can reduce the number of times coal is filled. The water jacket 8 is located on the outer periphery of the combustion chamber 6. The water jacket 8 is not connected to the combustion chamber 6 and is used for filling with water. The water is heated by radiating the high temperature generated by combustion in the combustion chamber 6 into the water jacket 8 to achieve the purpose of heating. The flue gas exhaust section 7 is located in the upper layer of the combustion chamber 6 inside the furnace body. The flue gas exhaust section 7 is located at the top of the end of the combustion chamber 6 near the coal inlet 3 and is connected to the combustion chamber 6. The flue gas generated by combustion in the combustion chamber 6 is discharged from the combustion chamber 6 through the flue gas exhaust section 7. The flue gas discharged through the exhaust section 7 is finally discharged out of the furnace body through the smoke outlet 4. The flue gas also passes through the first smoke guide cavity 9 and the second smoke guide cavity 10 between the exhaust section 7 and the smoke outlet 4. The second smoke guide cavity 10 is located at the top of the end of the combustion chamber 6 near the coal inlet 3 and is located on the upper layer of the exhaust section 7. The second smoke guide cavity 10 and the exhaust section 7 are connected through the first smoke guide cavity 9 and the smoke guide assembly. The first smoke guide cavity 9 is located on the upper layer of the end of the combustion chamber 6 away from the coal inlet 3 and is not directly connected to the combustion chamber 6. The smoke guide assembly includes a first smoke guide part and a second smoke guide part. The second smoke guide part connects the second smoke guide cavity 10 and the first smoke guide cavity 9. The first smoke guide part connects the first smoke guide cavity 9 and the exhaust section 7. The first smoke guide part and the second smoke guide part are exposed in the water jacket cavity 8. After the water jacket cavity 8 is filled with a certain amount of water, the water covers the first smoke guide part and the second smoke guide part.

[0046] In this embodiment, after the combustion chamber 6 is filled with coal, the coal is ignited from the end away from the coal inlet 3 and burns towards the coal inlet 3, maximizing the extension of the combustion path. After the high-temperature flue gas generated during coal combustion fills the combustion chamber 6, it is naturally drawn upward by the temperature difference and discharged from the combustion chamber 6 through the exhaust section 7. It then passes through the first smoke guide section, the first smoke guide cavity 9, the second smoke guide section and the second smoke guide cavity 10 in sequence, and is finally discharged from the furnace body through the exhaust port 4. By setting up a first smoke guide chamber 9, a second smoke guide chamber 10, and a smoke guide assembly, with the first smoke guide chamber 9 and the second smoke guide chamber 10 corresponding to the two ends of the combustion chamber 6 respectively, the length of the flue gas transport path in the furnace body is increased on the flue gas side. Firstly, this ensures that the high-temperature flue gas can fully react in the furnace body to reduce the emission of pollutants in the flue gas. Secondly, it also increases the heat exchange area of ​​the water in the water jacket cavity 8, effectively reducing the temperature of the flue gas by utilizing the heat exchange between the flue gas and the water to reduce the generation of nitrogen oxides, thereby reducing pollutant emissions. Thirdly, since the flue gas path inside the furnace body is increased, the flue gas path outside the furnace body can be reduced, thus reducing the height of the external flue duct and helping to stabilize the temperature inside the furnace. On the water side, by exposing the first and second smoke guide sections in the water jacket cavity 8, the water in the water jacket cavity 8 is not only heated by the heat radiated by the combustion chamber 6, but also exchanges heat with the high-temperature flue gas through contact with the first and second smoke guide sections, improving the thermal efficiency of heating water with high-temperature flue gas.

[0047] The stove provided in this embodiment can optionally use 100*100*90mm biomass composite square honeycomb briquettes as fuel. After thermoplastic packaging, the single package size is 300*200*270mm. The coal inlet 3 is designed to be compatible with the fuel size. Adding the fuel in whole packages greatly reduces the difficulty of operation and is clean and hygienic, achieving dust-free filling.

[0048] Furthermore, the furnace body includes an inner shell 1 and an outer shell 2. The inner shell 1 is provided with the combustion chamber 6, the first smoke guiding chamber 9 and the second smoke guiding chamber 10. The outer shell 2 is sleeved on the outside of the inner shell 1, and the water jacket cavity 8 is formed between the outer shell 2 and the inner shell 1. The coal inlet 3 is provided on the outer shell 2.

[0049] Specifically, the stove in this embodiment consists of two parts: an inner shell 1 and an outer shell 2. The inner shell 1 includes a top plate 22, a bottom plate 23, and a U-shaped first side plate 24. After the first side plate 24 and the bottom plate 23 are installed, the space enclosed by the first side plate 24 and the bottom plate 23 forms a combustion chamber 6. After the first side plate 24 and the top plate 22 are installed, one of the protruding positions on the top of the first side plate 24 and the space enclosed by the top plate 22 form a first smoke guiding chamber 9. A partition plate 25 is provided in the other protruding position on the top of the first side plate 24. The partition plate 25 holds the first side plate 24 in place. Another protruding section at the top is divided into two parts. One part forms the exhaust 7, which communicates with the combustion chamber 6. The other part cooperates with the top plate 22 to form the second smoke guide chamber 10. The outer shell 2 includes two L-shaped second side plates 26, which are fitted outside the first side plate 24. A water jacket cavity 8 is formed between the second side plate 26, the first side plate 24, the top plate 22, and the bottom plate 23. Multiple mounting holes 27 are provided on both second side plates 26. The mounting holes 27 are used to install tie rods, which are used to connect and fix the second side plate 26 to the first side plate 24. The coal inlet 3 is opened on one of the second side plates 26 and passes through the second side plate 26 and the first side plate 24. The smoke outlet 4 is opened on the top plate 22.

[0050] Furthermore, the smoke guiding assembly includes:

[0051] Multiple first smoke guide pipes 11, the first smoke guide pipes 11 connecting the smoke exhaust section 7 and the first smoke guide cavity 9;

[0052] Multiple second smoke guide pipes 12 are provided on the side of the first smoke guide pipe 11 away from the combustion chamber 6, and the second smoke guide pipes 12 connect the first smoke guide chamber 9 and the second smoke guide chamber 10.

[0053] Specifically, the smoke guiding assembly consists of a mounting plate 28, multiple first smoke guiding pipes 11, and multiple second smoke guiding pipes 12. The mounting plate 28 is installed between two protruding positions on the top of the first side plate 24 and is fixed to the first side plate 24. The channel formed by the mounting plate 28 and the top plate 22 connects to the water jacket cavities 8 on both sides of the furnace body. The multiple first smoke guiding pipes 11 and multiple second smoke guiding pipes 12 are installed on the mounting plate 28 and located within the channel formed by the mounting plate 28 and the top plate 22. A first smoke guide pipe 11 and multiple second smoke guide pipes 12 are arranged in two layers. One end of the first smoke guide pipe 11 is connected to the exhaust section 7, and the other end is connected to the first smoke guide cavity 9, for conveying flue gas from the exhaust section 7 into the first smoke guide cavity 9. The first smoke guide pipe 11 is exposed inside the water jacket cavity 8. One end of the second smoke guide pipe 12 is connected to the first smoke guide cavity 9, and the other end is connected to the second smoke guide cavity 10, for conveying flue gas from the first smoke guide cavity 9 into the second smoke guide cavity 10. The second smoke guide pipe 12 is exposed inside the water jacket cavity 8. By setting the smoke guide assembly in the form of multiple first smoke guide pipes 11 and multiple second smoke guide pipes 12, the heat exchange area between the smoke guide assembly and the water jacket cavity 8 can be increased, thereby improving the thermal efficiency of the flue gas and ensuring more effective cooling of the flue gas, thus reducing the generation of nitrogen oxides in the flue gas and reducing pollutant emissions.

[0054] Furthermore, the first smoke guide pipe 11 and the second smoke guide pipe 12 are inclined, and the distance between the end of the first smoke guide pipe 11 that is connected to the first smoke guide cavity 9 and the combustion cavity 6 is greater than the distance between the other end of the first smoke guide pipe 11 and the combustion cavity 6; the distance between the end of the second smoke guide pipe 12 that is connected to the second smoke guide cavity 10 and the combustion cavity 6 is less than the distance between the other end of the second smoke guide pipe 12 and the combustion cavity 6.

[0055] Specifically, the height of the end of the first flue pipe 11 connected to the exhaust section 7 is lower than the height of the end connected to the first flue chamber 9, satisfying the requirement for upward transport of high-temperature flue gas between the exhaust section 7 and the first flue chamber 9; the height of the end of the second flue pipe 12 connected to the first flue chamber 9 is lower than the height of the end connected to the second flue chamber 10, satisfying the requirement for upward transport of high-temperature flue gas between the first flue chamber 9 and the second flue chamber 10. By setting a height difference between the two ends of the first flue pipe 11 and the second flue pipe 12, the requirement for the high-temperature flue gas to rise is met, while also increasing the length of the first flue pipe 11 and the second flue pipe 12, thereby further increasing the length of the flue gas transport path and further increasing the heat exchange area between the first flue pipe 11 and the second flue pipe 12 and the water jacket cavity 8.

[0056] Furthermore, the outer shell 2 also has a ash removal port 5, which is connected to the end of the combustion chamber 6 away from the coal inlet 3.

[0057] Specifically, the ash removal port 5 is located on one of the second side plates 26, passing through the second side plate 26 and the first side plate 24, and connecting to the end of the combustion chamber 6 away from the coal inlet 3. The ash removal port 5 is equipped with a switchable cover for sealing it. The ash removal port 5 is used to clean the ash residue remaining after coal combustion. In addition, after the combustion chamber 6 is filled with coal, it is also ignited through the ash removal port 5.

[0058] Furthermore, the outer casing 2 is also provided with a pushing component, the pushing component comprising:

[0059] A rack 13 passes through the outer shell 2 and one end extends into the combustion chamber 6. A pusher plate 14 is installed at the end of the rack 13 that extends into the combustion chamber 6.

[0060] The drive device 15 has its output shaft connected to the rack 13 via a gear. The drive device 15 is used to drive the rack 13 along the extending direction of the combustion chamber 6.

[0061] Specifically, the pushing assembly is located on the side of the furnace body away from the ash removal port 5. The pushing assembly includes a rack 13, a pushing plate 14, and a driving device 15. The driving device 15 is fixed to the second side plate 26. The rack 13 passes through the second side plate 26 and the first side plate 24 where the driving device 15 is installed and extends into the combustion chamber 6. The extending direction of the rack 13 is parallel to the extending direction of the combustion chamber 6. The pushing plate 14 is installed at the end of the rack 13 that extends into the combustion chamber 6. The pushing plate 14 is used to contact the coal. The driving device 15... A transmission gear is fixed on the output shaft, and the transmission gear meshes with the teeth on the rack 13. By starting the drive device 15, the drive shaft of the drive device 15 rotates, which drives the rack 13 to enter and exit the combustion chamber 6. When the rack 13 moves into the combustion chamber 6, the pusher plate 14 pushes the coal from the coal inlet 3 to the ash removal port 5, which facilitates the filling of coal. After the coal near the ash removal port 5 in the combustion chamber 6 has burned out, the complete ash residue after coal combustion can also be pushed out of the ash removal port 5 by the pusher assembly. In this embodiment, the drive device 15 is driven by a hand crank. In other embodiments, the drive device 15 can also be driven by a motor.

[0062] Furthermore, the combustion chamber 6 is provided with a support frame 16 for supporting coal. The support frame 16 extends from the coal inlet 3 to the ash removal inlet 5, and the support frame 16 is provided with an ash drop hole 17.

[0063] Specifically, the coal does not contact the bottom plate 23 within the combustion chamber 6. Instead, it is suspended within the combustion chamber 6 by being placed on a support frame 16. The support frame 16 consists of multiple horizontally arranged and multiple vertically arranged support columns 18, which are installed on the inner wall of the first side plate 24. Ash collection holes 17 are formed between adjacent support columns 18. By providing ash collection holes 17, on the one hand, the ash fragments that fall off after the coal combustion can fall through the ash collection holes 17, preventing them from remaining on the support frame 16 and affecting the subsequent coal loading. On the other hand, the ash collection holes 17 also allow the bottom of the coal to contact the air, increasing the air contact area and improving combustion efficiency.

[0064] Furthermore, a dust removal drawer 21 is provided below the support frame 16.

[0065] Specifically, the ash removal drawer 21 is located below the end of the support frame 16 near the ash removal port 5, and is used to collect debris falling from the ash discharge hole 17. An opening is provided on the second side plate 26 corresponding to the position of the ash removal drawer 21, allowing the ash removal drawer 21 to be pushed and pulled. A ventilation hole 29 is provided on the ash removal drawer 21, which connects to the combustion chamber 6 and the outside of the furnace body for ventilation of the combustion chamber 6.

[0066] Furthermore, the outer casing 2 is provided with a vent 19, which is connected to the combustion chamber 6, and the position of the vent 19 is lower than that of the support frame 16.

[0067] Specifically, the combustion chamber 6 is divided into two parts by a support frame 16. The part above the support frame 16 is used for combustion, and the part below the support frame 16 is used for ventilation. A vent 19 is located on the second side plate 26, passing through the second side plate 26 and the first side plate 24, and connecting to the combustion chamber 6 below the support frame 16. The vent 19 connects the bottom of the combustion chamber 6 to the outside of the furnace body, ensuring airflow to the bottom of the combustion chamber 6. A switchable cover is provided at the vent 19 to close it.

[0068] Furthermore, the inner shell 1 is provided with an air guide passage 20, one end of which is connected to the vent 19 and the other end is connected to the smoke exhaust section 7.

[0069] Specifically, the air guide passage 20 is located inside the second side plate 26. The air guide passage 20 is used to connect the vent 19 to the smoke exhaust section 7 and is connected to the smoke exhaust section 7 through multiple air holes 30, thereby guiding a portion of the air entering through the vent 19 to the smoke exhaust section 7. The air guide passage 20 is used on the one hand to provide air from the top of the combustion chamber 6 into the combustion chamber 6 to assist the combustion of coal, and on the other hand, it can also allow the flue gas at the smoke exhaust section 7 to react further, thereby reducing pollutants generated due to incomplete combustion.
