How to solve the problem of black smoke when small boilers burn wood?

Although everyone basically cooks with electricity now, some people in remote mountainous areas and rural areas are still cooking with small boilers. In the past, our family used to burn wood and cook with a boiler, but in the process of burning wood, there will be some black smoke, which is not good for people to smoke too much.

We can reduce the production of black smoke from the following aspects. First of all, when we choose firewood, we should try to choose some dead branches that have been exposed to the sun for a long time. These dead branches are flammable and will not emit black smoke. If the branches burn before they are dry, the fire is difficult to burn, and it needs to evaporate water to burn, which will produce a lot of carbon monoxide and carbon dioxide. So we try to choose dry branches to burn, so as to avoid the generation of black smoke. Another is that we need some skills to put firewood in the process of burning. Try to frame all the firewood, so that the gap between firewood and firewood is empty, which can increase the contact area with oxygen and help combustion. This can also avoid the generation of black smoke, and also maximize the use of burning materials to avoid the waste of materials. There is another way to make fuel and air contact more, that is, we let more air into fuel during combustion. How do we do this? We can use a fan, or a small fan to help fan the wind, so that the flame will burn faster, which can also avoid the generation of black smoke.

However, some black smoke will be produced in the process of burning wood with a small boiler, so it is best not to burn wood with a small boiler if conditions permit. Burning firewood not only pollutes the air, but also harms forest vegetation.
