[0002] In rural areas or urban suburbs, there are still a lot of people using firewood stoves, and now firewood cooking is popular in rural areas or tourist areas. As the name suggests, firewood stoves are used to heat and use the heat from burning firewood to boil water or cook. In rural areas, this type of firewood stove is generally built with bricks and cement. The consumption of firewood for boiling water or cooking is relatively large, and the use of firewood is not high. At present, with the development and progress of the times, many of these firewood stoves are industrialized and mass-produced with metal materials. However, if you want the firewood in the stove to burn vigorously, you need to introduce a lot of air into it to help combustion, but the consumption of firewood will increase significantly. Therefore, all kinds of firewood stoves currently have a common problem: under a certain amount of firewood burning, the heat released and the combustion efficiency are not very high, which is also the place where this kind of stove urgently needs to be improved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0022] See also Figure 1 to Figure 3The utility model is a steam flame enhanced wood-burning stove, comprising a furnace shell 3 and an inner tank 5 for burning firewood, the upper end of the furnace shell is open, further, the outer sides of the furnace shell in the utility model are provided with lifting handles 1, the upper end of the inner tank is open, the inner tank is inserted into the furnace shell from top to bottom, and the upper port edge of the inner tank covers the upper port of the furnace shell; an isolation plate 10 is provided below the bottom of the inner tank, the isolation plate is placed in the furnace shell, the space between the bottom of the furnace shell and the bottom of the isolation plate is a water storage space 11, and a water injection pipe 4 is provided on the side wall of the furnace shell in the water storage space, further, the water injection pipe in the utility model is an L-shaped bent metal pipe, and the outer port of the water injection pipe faces upward Placement, at least two water vapor passages 9 arranged evenly spaced apart are arranged on the isolation disk outside the inner pot, one end of the water vapor passage is fixed to the isolation disk and connected to the water storage space 11, and the other end of the water vapor passage is connected upward to the upper side wall of the inner pot and communicates with the inner pot; a plurality of steam holes 8 are also arranged on the side wall of the inner pot, and the steam holes connect the inner and outer spaces of the inner pot. Further, the steam holes in the utility model are arranged in 2 to 4 circles from top to bottom, and each circle of steam holes is distributed in an annular shape on the side wall of the inner pot, and the spacing between the upper and lower layers of steam holes is consistent; a vent 2 is arranged on the outer wall of the furnace shell, and a plurality of vents 6 are arranged at the bottom of the inner pot. Further, a gap is left between the outer edge of the isolation disk and the inner side wall of the furnace shell in the utility model, and the gap distance is 0.1 to 0.5 mm; the number of water vapor passages on the isolation disk is set to three, and the three water vapor passages are arranged in an annular shape evenly spaced apart around the inner pot.
[0023] Furthermore, the furnace shell and the inner tank in this embodiment are both cylindrical with an open upper end, the outer diameter of the inner tank is smaller than the inner diameter of the furnace shell, and a stepped ring plate 7 extending outward is provided on the upper end of the inner tank, and the stepped ring plate is clamped on the upper end of the furnace shell. Furthermore, the furnace shell and the inner tank in this utility model are both made of high temperature resistant metal materials.
[0024] like Figure 4, is a schematic diagram of the structure of the utility model when it is in use. In order to facilitate clear viewing, the furnace body shell and the inner tank are mainly cut open for illustration. When in use, the inner tank is sleeved in the furnace body shell, and the upper port is sealed by a stepped ring plate. Firewood is placed in the inner tank, and a kettle is placed on it to boil water. Water is placed in the water storage space. When the firewood burns, the inner tank is heated, the temperature inside the furnace body shell rises, and the water in the water storage space below is heated and evaporates continuously. Water vapor enters the inner tank upward through three water vapor pipes, and the water vapor reacts with the unburned charcoal in the firewood to generate carbon monoxide. Some water vapor also penetrates upward through the gap at the outer edge of the isolation plate, and then enters the inner tank through the steam hole to generate carbon monoxide gas. The carbon monoxide can be further burned by heating, so the flame in the inner tank will burn more vigorously, and the same amount of firewood can be burned fully.
[0025] Through the inventor's actual test comparison, if the normal amount of firewood is 5kg and a pot of water is 4.8kg, in the stove, when there is no water, at most 7 pots of water can be boiled, and the time interval between boiling every two pots of water is about 10-15 minutes. After adding water below, at most 9 pots of water can be boiled, and the time interval between boiling every two pots of water is about 8-10 minutes. The firepower is stronger and the efficiency is significantly higher.
[0026] In the utility model, the inner tank and the furnace body shell adopt a split structural design, and any part that is broken can be directly replaced or repaired, which is convenient, fast and low in cost.
[0027] Through the above analysis, it can be seen that the improvement of the utility model can significantly improve the combustion efficiency of firewood in the wood stove, which has a significant effect on its promotion and application in rural areas.
[0028] On the basis of an ordinary firewood stove, the utility model uses additional water vapor to make the firewood in the inner tank burn more vigorously and fully, and the efficiency is also higher. Under the condition of the same amount of firewood, the flame of the stove of the utility model is larger and more durable, and the advantages are obvious. After the improvement of the utility model, the structure of the entire stove is very simple, the production cost is low, but the use effect is outstanding, especially in ordinary farm families, when a relatively small amount of firewood is used, the stove flame burns more vigorously, and the fire for boiling water and cooking is more vigorous and more efficient. As a practical tool, the utility model has good practical use and promotion value.
