Description

Technical Field

[0001] The utility model relates to the technical field of stoves, in particular to a combustion device of a fuel stove. Background Art

[0002] A stove is a device that generates heat energy by burning fuel. According to the different types of fuel materials, stoves can be divided into kerosene stoves, gas stoves, wood stoves and other types. In recent years, with the needs of new rural construction and energy conservation and environmental protection, the development and utilization of biomass pellet fuel stoves has attracted more and more attention and has been gradually promoted and applied. Existing biomass pellet stoves generally include a furnace body, which is provided with a combustion chamber. The fuel burns in the combustion chamber to generate heat energy. In order to fully burn the fuel, it is generally necessary to ventilate the combustion chamber so that oxygen in the air can enter the combustion chamber so that oxygen can play a combustion-supporting role in combustion.

[0003] In the prior art, a patent document with a publication number of "CN213841031U" discloses a stove capable of full combustion, comprising a stove, a burner arranged on the stove, an oil spray nozzle arranged on the burner, and an air inlet pipe arranged at the bottom of the burner, the burner comprising a hollow burner shell and a furnace core whose bottom can extend into the burner shell, a ventilation cavity is formed between the inner wall of the burner shell and the outer wall of the furnace core, and both the burner shell and the bottom of the furnace core are provided with a through air inlet, a plurality of through ventilation holes are arranged in an annular manner on the outer wall of the furnace core, wind from the air inlet pipe is blown into the ventilation cavity and the furnace core through the air inlet, and wind in the ventilation cavity is blown into the furnace core through the ventilation holes, by adopting the patented technology, fuel is sprayed into the furnace core through the oil spray nozzle, and the wind direction entering through the inclined ventilation holes can be opposite to the injection direction of the fuel, forming a counter-spray, which can concentrate the fuel in the central combustion area, so that the fuel can be fully burned, and can effectively prevent the fuel from being sprayed onto the inner wall of the furnace core, thereby avoiding the accumulation of oil stains. However, for stoves using biomass pellet solid fuel, the solid fuel is very easy to accumulate into clumps in local areas, making it impossible for the solid fuel to burn fully. On the other hand, although ventilation can help the fuel burn, if the wind is too strong, the fuel will move toward a local direction in the stove and accumulate into clumps, which will not only affect the combustion effect of the fuel, but also cause uneven heat generation around the stove.

[0005] The utility model is realized through the following technical solutions.

DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0024] The utility model provides a combustion device for a fuel stove, such as Figures 1 to 5 As shown, it includes a furnace box 1, a pair of partitions 2 are arranged in the furnace box 1, a plurality of air distribution holes 3 are arranged on the surface of the partition 2, and the partition 2 divides the internal space of the furnace box 1 into an air distribution chamber 4 and a combustion chamber 5, and a feed hole 6 and an air inlet hole 7 are also arranged on the surface of the furnace box 1, the air distribution chamber 4 is connected with the air inlet hole 7, and the combustion chamber 5 is connected with the feed hole 6, and a material guide plate 8 is also arranged in the combustion chamber 5, and the left and right sides of the material guide plate 8 are respectively fixedly connected to the partition 2, and one end of the material guide plate 8 is also fixedly connected to the lower edge of the inner wall of the furnace box 1, and an ash unloading hole 9 is formed between the other end of the material guide plate 8 and the inner wall of the furnace box 1, and the ash unloading hole 9 is close to the upper edge of the inner wall of the furnace box 1.

[0025] By adopting the technical solution of the utility model, biomass particle solid fuel is fed into the combustion chamber through the feed hole. Since the air distribution chamber is arranged on the left and right sides of the combustion chamber, the airflows from the air distribution chamber blow against each other, which can avoid local accumulation of solid fuel into a mass, and make the solid fuel evenly spread on the surface of the guide plate, and then make the solid fuel fully burn and release the maximum heat energy. In addition, the airflow can also be fed into the combustion chamber through the feed hole, which has a direct combustion-supporting effect on the solid fuel in the combustion chamber. As the solid fuel burns, the burned fuel is lighter in weight and is blown to the rear end of the guide plate by the airflow, which also makes the solid fuel evenly spread on the surface of the guide plate, further making the fuel fully burn. When the solid fuel is finally burned into ash, the ash can fall out of the combustion chamber from the ash discharge hole.

[0026] Specifically, the projection of the guide plate 8 on the surface of the partition plate 2 is S-shaped. The surface of the guide plate 8 is also provided with a plurality of ash leakage holes 10. The number of the ash leakage holes 10 is multiple, and the multiple ash leakage holes 10 are arranged on the surface of the guide plate 8 in a linear array. With the technical solution of the utility model, some solid particle fuels are burned first and become ash, and part of the ash can be directly discharged from the ash leakage holes 10 outside the combustion chamber to prevent the ash from affecting the fuel combustion effect.

[0027] In addition, there are two air distribution chambers 4, which are arranged on the left and right sides of the combustion chamber 5. With the technical solution of the utility model, the airflow is first sent into the air distribution chamber 4 through the air inlet hole 7, and then sent into the combustion chamber 5 through the air distribution hole 3. The airflow process undergoes a turning point, thereby reducing the kinetic energy of the airflow, which can avoid blowing away the ashes, and the airflows entering the combustion chamber from both sides blow against each other, which can avoid local accumulation of solid fuel, so that the solid fuel is evenly spread on the surface of the guide plate, and then the solid fuel is fully burned to release the maximum heat energy.

[0028] In addition, an ignition hole 11 is provided on the surface of the furnace box 1, and the combustion chamber 5 is also connected to the ignition hole 11. During the initial ignition, the igniter is extended into the combustion chamber through the ignition hole. Since the airflow can enter the combustion chamber through the feed hole, the flame is blown into the combustion chamber, so that the solid fuel is easily ignited in the combustion chamber. When the solid fuel burns in the combustion chamber, since the airflow enters the combustion chamber through the feed hole, it can prevent the ash from flowing back in the opposite direction and blocking the igniter in the ignition hole 11, thereby ensuring the normal use of the igniter.

[0029] Specifically, the furnace box 1 is also fixedly connected to one end of the furnace barrel 12, and the other end of the furnace barrel 12 extends upward in the vertical direction. The surface of the furnace box 1 is also provided with a flow hole, and the flow hole is surrounded by the furnace barrel 12. The heat energy generated by the combustion of the solid fuel is sent upward through the furnace barrel 12. The furnace box 1 is also fixedly connected to the ash discharge frame 13, and the ash discharge frame 13 is arranged below the guide plate 8. The ash generated by the solid fuel falls into the ash discharge frame 13 through the ash discharge hole and the ash leakage hole, and is concentrated under the guidance of the ash discharge frame 13, so as to facilitate the timely removal of the ash and avoid affecting the full combustion of the solid fuel.

[0030] In addition, the surface of the furnace box 1 is also fixedly connected to the ear plate 14. Therefore, the combustion device provided by the utility model has a high degree of integration and modularization, and can be installed on various types of stoves using simple fasteners such as bolts, which is conducive to expanding the scope of application of the utility model and facilitating batch production management. There are multiple air distribution holes 3, and the multiple air distribution holes 3 are arranged on the surface of the partition plate 2 in a linear array.
