What is the purpose of virtual fire?

The purpose of misfire is to increase the contact area between combustible materials and oxygen.

There is an old saying: "People should be honest and fire should be empty." This sentence means that a person should be down-to-earth if he wants to succeed in his career; Combustible materials should be placed on the top of the head to burn more brightly. Combustion is a violent chemical reaction between combustible substances and oxygen. "Fire must be empty" means that the combustion reaction can only be maintained if the fuel is in good contact with oxygen, otherwise the oxygen supply will be insufficient and the fire will not burn well or even be extinguished.

First, the definition of combustion.

Combustion refers to the exothermic reaction between combustible and oxidant, usually accompanied by flame, luminescence and smoke. Combustion is an exothermic and luminous chemical reaction, and its reaction process is extremely complicated. The chain reaction of free radicals is the essence of combustion reaction, and light and heat are physical phenomena in the combustion process.

Second, the three elements of combustion

1, flammable. Combustible refers to substances that can react with oxygen or other oxidants in the air, such as wood, paper and cloth. Some items in combustible materials are particularly easy to burn when exposed to open flames. They are called flammable materials, and the common ones are gasoline, alcohol and liquefied petroleum gas.

2. Combustion-supporting materials. Combustion-supporting materials are substances that can help and support the combustion of combustible materials, that is, substances that can undergo oxidation reactions with combustible materials (such as air and oxygen).

3. Ignition source.
