Is backflow incense harmful?

Backflow incense is a rather peculiar phenomenon. The smoke will flow from top to bottom along the incense burner, forming an effective flowing landscape. Such incense can keep the fragrance completely on the ground and is not easily inhaled into the lungs to affect the body. Backflow incense is often used to kill insects and enhance fragrance. It is very useful in life. Let's take a look at whether backflow incense is harmful? I hope everyone can understand it.

Backflow incense burner: The backflow incense burner is a kind of incense utensil. Because it ignites cone incense, the density of the smoke produced during the burning process is greater than the density of the air, which will produce a backflow effect, similar to a waterfall. Hence the name: Backflow Incense Burner. In terms of material, backflow incense can be divided into stone, ceramic, etc. Most backflow incense burners are black or dark gray-brown in color, so that they can create a sharp contrast with the smoke produced by the burning incense.

Backflow incense can produce more floating particles (PM2.5), so it is better to burn it less in a closed room.

1. The specially made tower incense has a small hole inside to facilitate the smoke to flow downward.

2. The backflow furnace has a hole or a slot aimed at the small hole of the tower incense, which is also conducive to the downward flow of smoke. After placing the incense utensils, light the agarwood. Do not extinguish the flame immediately. Let the flame burn slightly for 4-6 seconds. When you see that it is burned more fully, fan out the flame and put it into a special backflow furnace. At first, there will be no smoke flowing from the bottom. After about one or two minutes, the smoke changes direction and flows out slowly from the bottom.

3. The particles contained in smoke are heavier than air. As long as there is no wind in the room and the hot air rising from the combustion and heating is isolated to prevent the hot air from carrying the smoke up, the smoke will sink. There are relatively more impurities mixed in the smoke, that is to say, more impurity particles are produced when the incense is lit. The smoke particles are heavier than the air, and the smoke sinks downwards.

The above is an explanation of whether backflow incense is harmful. I hope everyone can understand that this is a very useful kind of incense, but it needs to be used reasonably.
