Description

Technical Field

[0001] This utility model belongs to the field of combustion furnace technology, and in particular relates to a novel combustion furnace. Background Technology

[0002] In winter, it is common to use stoves for heating or cooking. Existing stoves, regardless of whether they use coal or biomass pellets as fuel, produce a large amount of dust. Over time, this dust gradually accumulates in the internal flue pipes, causing blockages.

[0003] To facilitate cleaning, existing combustion furnaces typically have a removable side plate on one side wall, secured with bolts for easy assembly and disassembly. The internal piping is then accessed by removing the side plate. While this method achieves the goal of disassembly and cleaning, the process is extremely cumbersome and time-consuming. Furthermore, the bolts are prone to aging and deformation due to high-temperature combustion, causing considerable inconvenience to users.

[0004] Secondly, the existing combustion furnaces also have the function of using circulating water to heat the room, but the function is relatively simple and there are no other functions, such as the function of connecting to a faucet to provide warm water for washing.

[0005] In addition, taking biomass pellets as an example, existing stoves can only burn biomass pellets and cannot use fuels such as wood or coal, which is inconvenient to use. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1 to 7As shown, this utility model provides a novel combustion furnace, including a furnace body 1. The furnace body 1 contains a combustion chamber 3 and a fuel bin 4. Fuel is fed from the bottom of the fuel bin 4 onto a grate 6 at the bottom of the combustion chamber 3 via a feeding component 5 (i.e., a feeding auger). An igniter corresponding to the grate 6 is installed inside the furnace body 1. The igniter ignites the fuel, causing it to burn on the grate 6. The feeding auger can automatically feed the fuel, ensuring continuous combustion. Two feeding augers can be used to improve feeding stability.

[0034] At least one fire pipe 11 is provided on the outside of the combustion chamber 3, and multiple fire pipes are provided as shown in the figure. The fire pipes 11 are located in the hot water jacket 8 between the combustion chamber 3 and the furnace body 1 to heat the water in the jacket. The water in this hot water jacket 8 is used for heating and is connected to the radiator through pipes for recycling. The hot water inlet 13 of the hot water jacket 8 is at a lower height, and the hot water outlet 10 is at a higher height, which can improve the heat exchange efficiency.

[0035] The furnace body 1 has a quick-release side plate structure on at least one side, which allows for rapid disassembly and cleaning of internal ash and slag, facilitating use. The quick-release side plate structure includes a side plate 2, preferably located near the end of the fire pipe 11. The side plate 2 is detachably connected to the furnace body 1 via at least one locking latch 14, allowing for quick assembly and disassembly without the need for screwdrivers, wrenches, or other tools. After each heating season, it can be easily cleaned for reuse the following year. The side plate 2 has a smoke exhaust port 12, which corresponds to the end of the fire pipe 11, allowing for the installation of an induced draft fan to quickly expel the smoke from the fire pipe 11.

[0036] The furnace body 1 is also equipped with a medium heat exchange structure, which includes a heat exchange coil 9 placed in the hot water jacket 8. The two water circuits are independent of each other and do not interfere with each other. The water in the hot water jacket 8 is used for heating, and the water in the heat exchange coil 9 is used for washing. The water in the heat exchange coil 9 can exchange heat with the water in the hot water jacket 8, making the water for washing warm and comfortable, greatly facilitating people's daily washing needs.

[0037] As a further improvement, the heat exchange inlet 91 of the heat exchange coil 9 is located near the bottom of the warm water jacket 8, and the heat exchange outlet 92 of the heat exchange coil 9 is located near the top of the warm water jacket. This allows for gradual preheating of the incoming cold water, with the water near the top having the highest temperature and thus the highest output heat, making it convenient to use.

[0038] As a further improvement, the grate 6 is detachably connected to the combustion chamber 3, which facilitates cleaning and maintenance after disassembly.

[0039] To enable diverse fuel choices, the combustion chamber 3 is further equipped with a second grate 7 located above the first grate 6, and the combustion chamber 3 also includes supporting steps for mounting the second grate 7. The addition of the second grate 7 allows for a wider range of fuel options. For example, when biomass pellets are depleted, or when other fuels (wood, straw, etc.) are available, the fuel can be burned on the second grate 7, expanding fuel choices and eliminating the need to rely solely on biomass pellets. This is particularly suitable for users outside of urban areas.

[0040] The beneficial technical effects of this utility model are as follows:

[0041] The side panels are detachably connected to the furnace body via locking buckles. Compared with the previous bolt-fastening connection method, this allows for quick assembly and disassembly without the need for wrenches or other tools, making the operation simpler and more convenient.

[0042] The heating water jacket is also equipped with heat exchange coils, which can provide not only heating but also hot water for washing. The two water circuits are independent of each other and do not interfere with each other, greatly expanding the functionality.

[0043] By adding a second grate to the combustion chamber, it can also burn fuels such as charcoal, and is not limited to burning biomass pellets, giving users a wider range of fuel options.

[0044] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
