Hydrogen Flammability Limits
"On the Burnable Limits of Hydrogen"
Hydrogen is the genus of gas, and its characteristics are unique. In the matter of combustion and explosion, the limit is crucial.
The flammable limit of hydrogen is the core of combustion and explosion. The lower limit is the minimum concentration of hydrogen in air and other media that can maintain combustion. If the concentration of hydrogen is below this lower limit, although it encounters a source of fire, it is difficult to burn. Due to insufficient fuel, it is difficult to maintain the continuity of the chain reaction.
The upper limit is the highest concentration of hydrogen that can be burned in the medium. If the concentration exceeds this upper limit, although there is sufficient fuel, oxygen and other accelerants are relatively scarce and cannot burn normally.
When the concentration of hydrogen is within the flammable limit, it can explode instantaneously in case of ignition sources such as open flames and hot topics. Its power is amazing, and it can cause damage to objects and people.
Observe the factors affecting its limit, temperature, pressure, container shape, etc. are all powerful. When the temperature increases, the flammable limit widens, and due to the enhanced molecular activity, it is more prone to reaction; when the pressure increases, the limit changes, or wide or narrow, depending on the specific situation. The shape of the container, whether narrow or wide, also has different effects on the explosion limit of hydrogen.
Therefore, in all matters involving hydrogen, such as production, storage, transportation, etc., it is necessary to know the flammable limit of hydrogen. Strictly abide by the safety procedures, control the concentration of hydrogen outside the safe range, and prevent the micro-gradually, so as to ensure safety. This is an important matter related to people's livelihood and industry, and cannot be ignored.
