põlemispiire
Põlemispiire, also known as the flammability limits or explosive limits, refers to the range of concentrations of a flammable gas or vapor in a mixture with air or another oxidant at which ignition and self-sustained combustion can occur. Below the lower põlemispiire, the concentration of the fuel is too low to support combustion, and the mixture will not ignite or sustain a flame. Above the upper põlemispiire, the concentration of the fuel is too high, and there is not enough oxidant (typically oxygen) to support combustion.
The põlemispiire are usually expressed as percentages by volume. For example, methane has a lower põlemispiire
Factors such as temperature, pressure, and the presence of inert gases can influence the põlemispiire. Higher
Understanding põlemispiire is crucial for safety in industrial settings where flammable materials are handled. It helps
