What is the principle of reflowing incense?

The principle of reflow incense is to cool the flue gas through a long channel, and then the aroma particles are larger and denser. In this way, when coming out of the air outlet, the smoke density is a little higher than the outside air, and naturally flows downward.

Reflux incense burners use special incense towers, most of which are conical and hollow. By isolating hot air, the smoke is locked in a pagoda-shaped hollow incense column for cooling, and the smoke sinks to the ground because it is heavier than air, which is what we often say. When the dust settled, the sinking smoke flowed out through the small holes at the bottom of the incense column, forming the backflow incense we saw.

Details:

1, special tower incense, with a small hole in it, which is conducive to the downward flow of smoke.

2. After setting the incense burner, light the heavy smoke incense. Don't put out the flame at once. Let the flame burn slightly for 4-6 seconds, and then see if the combustion is sufficient. Fan out the flame and put it in a special reflux furnace. At first, there will be no cigarette butts coming out from the bottom. After about a minute or two, the cigarette changed direction and slowly flowed out from the bottom.

3. Smoke contains particles heavier than air. As long as there is no wind in the room and it is isolated from the rising hot air around the burning and heating, and the hot air is not allowed to rise with smoke, the smoke will sink. There are more impurities in smoke, that is to say, more impurity particles can be produced when incense is lit. The proportion of smoke particles is greater than that of air, and the smoke sinks.
