Flammability in hydrocarbons

WebAug 1, 2003 · The flammability limits, which are also referred to as the explosive limits, provide the range of fuel concentration, usually in percentage volume at 298 K, within which a gaseous mixture in air can ignite and burn. Below the lower flammability limit (LFL) there is not enough fuel to cause ignition. WebThey are very flammable and have a low viscosity because they are gases. The hydrocarbons in different fractions differ in these properties. For example, the bitumen …

WebThe Flammable Range(also called Explosive Range) is the concentration range of a gas or vapor that will burn (or explode) if an ignition source is introduced. Three basic requirements must be met for explosion to take place: flammable substance - fuel oxidizer - oxygen or air source of ignition - spark or high heat

The noteworthy feature of saturated hydrocarbons is their inertness. Unsaturated hydrocarbons (alkanes, alkenes and aromatic compounds) react more readily, by means of substitution, addition, polymerization. At higher temperatures they undergo dehydrogenation, oxidation and combustion.
