An old tree in Nanjing suddenly began to smoke from the inside, and the fire extinguisher could not be put out. Why is this happening?

Have you all encountered strange phenomena in your life? Such a strange thing happened in Nanjing. The heart of an old tree suddenly spontaneously ignited and began to smoke from the inside. Passers-by were surprised when they found out. An enthusiastic citizen nearby said that the old tree was smoking under it, but it didn't go out after pouring several buckets of water and fire.

The citizens also took out the fire extinguishers at home to put out the fire. As a result, several fire extinguishers were used up, but it was still useless. Finally, they can only dial 1 19. When the firemen came, they found a fire in the tree, which made people feel very surprised. It is reported that this is a normal natural phenomenon, because the moisture content of bark is higher than that of tree core, and the moisture content of dead tree core is low, so the tree core is on fire, but the appearance of the tree is not on fire.

It may also be because of the smoldering phenomenon of dead branches and rotten leaves and peat layers for many years, and this phenomenon will also occur. The core of the tree is on fire and the appearance is not burning. Many people have talked about the cause of the spontaneous combustion of this tree, and there are many voices of debate on the Internet.

The opinions of netizens are mainly divided into two categories. One is that the spontaneous combustion of trees is caused by high temperature, and the other is man-made, such as throwing flammable items such as elbows, but firefighters have explained that it is the internal combustion of trees, which should not be man-made.

Judging from the situation on the spot, we can get the answer. No burning cigarette butts, garbage and other items were found around the burning trees. If it is man-made, it can be doused with water and fire extinguishers, but the public used water and fire extinguishers, but the result was not doused, so it can be determined that the burning occurred from inside the trees.

The burning of this tree is spontaneous combustion, which belongs to smoldering in high temperature, oxygen deficiency and humid environment. Fortunately, it was handled in time, and there were no more flammable materials around, so the fire did not spread, so you should call 1 19 in time when you see this situation.
