It is light, so it will rise and form air convection."

The audience nodded, it was easy to understand.

"When the bottom of our furnace is burning, the air will heat up, expand, and then rise, and the cold air above will sink. The relative flow speed depends on the temperature difference. As long as the chimney is high enough, the air above us will be closer to the natural temperature.

In other words, it is colder, the greater the temperature difference, and the faster the flow speed. Can you understand this?"

The audience continued to nod.

"Once the air flows and the speed is fast enough, we will have enough oxygen to support combustion, improve combustion efficiency and temperature, and it is equivalent to a natural blower."

Utilizing the principle of hot air rising, hot smoke is discharged from the upper air outlet, and fresh cold air from outside is drawn in from the inlet, which increases the oxygen required for fuel combustion, makes the fuel burn more fully, and enhances the intensity of the fire.

This is the principle of blast furnace.

Blast furnace smelting of iron sounds powerful, but it actually means iron produced in a blast furnace.

One of the main reasons for limiting materials throughout the ages has been combustion temperatures and furnaces that can withstand high temperatures.

The audience suddenly realized.

【Fuck, I got it!】

[Holy crap, is this so scientific? I always thought Boss Fang came from the world of metaphysics, dog head]

[You think I am science, but actually I am metaphysics!]

【There are always people wearing the guise of science to show us magic.】

"The same goes for high-rise buildings. The hot air caused by low-rise fires will flow upward through the channels, allowing the hot gas to accumulate at the top. As a result, the fire will convection through the air, creating another fire scene on the top floor of the building."

"So don't run up when escaping from a fire. You must go down."

Bi Fang dug a hole that could accommodate half of his body and began to build a stove out of clay.

[Is it really reliable to make iron with iron bacteria? It feels like Magneto sucking out iron from the human body]

[I also think it’s a bit mysterious, but if I say no, I bet 50 cents that Boss Fang will slap me in the face. Funny]

"There is no problem, whether it is theoretical or practical, it can be successful."

Bi Fang piled a large piece of clay on the ground, spread it in the pit, and glued a layer around it.

"Iron bacteria can oxidize divalent iron into ferric iron and obtain energy from it. In water, they can oxidize ferrous iron compounds and precipitate them to form trivalent iron hydroxide."

"Sediments gather around bacteria and produce a large amount of brown slime, which leads to pitting corrosion and the formation of rust tumors on equipment and pipes. Many times, this is the brown rust we see in pipes."

"Because of this, it can oxidize ferrous hydroxide dissolved in water, and ferrous carbonate is deposited into ferric hydroxide, which plays a role in concentrating and accumulating iron elements in the environment. Many scientists also believe that it may be natural brown iron.

Participants in the formation of mineral deposits.”
