Why not fire itself off?

Normally, the process of generating CO2 and water vapor, are substances that are incapable of maintaining combustion. These substances will envelop the fire,

Prevent it from contacting the air. So, the flame must be turned off right from the start of its formation?

But why didn't that happen? Why does the burning process continue without stopping when storing unburnt fuel? The only reason is, the gas after warming will expand and become lighter . Therefore, hot products of combustion do not stay where they are formed (directly near the fire), but get cold and heavier by new air, pushing up quickly.

Here, if Acsimet's law is not applied to the gas (or, if there is no gravity), then any fire will only burn for a moment and will turn itself off immediately. In a weak, attractive environment, the fire will have a very odd shape.

We can easily see the harmful effects of fire products on fire. You often accidentally use it to turn off the fire in the lamp. How often do you blow off kerosene lamps? You blow from the top down, that is, down to the fire, the products are not flammable (due to burning), and the fire is off because there is not enough air.
