    Aug 23, 2014 · If oxygen is the oxidizing element of the atmosphere used to continue fueling the flames, the air only needs 16% minimum. Air contains 21% oxygen. However, other sources of combustion are available, such as fluorine burning water, or hydrogen burning chlorine.

Limiting oxygen concentration - Wikipedia

    https://en.wikipedia.org/wiki/Limiting_oxygen_concentration
    The limiting oxygen concentration, (LOC), also known as the minimum oxygen concentration, (MOC), is defined as the limiting concentration of oxygen below which combustion is not possible, independent of the concentration of fuel. It is expressed in units of volume percent of oxygen. The LOC varies with pressure and temperature. It is also dependent on the type of inert (non-flammable) gas.

Limiting oxygen index - Wikipedia

    https://en.wikipedia.org/wiki/Limiting_oxygen_index
    The limiting oxygen index (LOI) is the minimum concentration of oxygen, expressed as a percentage, that will support combustion of a polymer. It is measured by passing a mixture of oxygen and nitrogen over a burning specimen, and reducing the oxygen level until a critical level is reached.

The Chemical Composition of Normal Air Vs. Pure Oxygen ...

    Combustion is a chemical reaction in which hydrocarbons combine with oxygen, producing carbon dioxide, water vapor and energy. Air provides enough oxygen to easily support combustion, whether the fuel is wood, gasoline, methane or coal. In pure oxygen, however, combustion and fire become significantly greater hazards.
