Liquefied Petroleum Gas (LPG) is a mixture of light hydrocarbons, primarily propane and butane, produced during crude oil refining and natural gas processing. LPG is highly flammable and is stored as a liquid under pressure, while it exists as a gas under atmospheric conditions.

Due to its high calorific value and relatively cleaner combustion compared with many conventional fuels, LPG is widely used in industrial applications, transportation, and residential heating and cooking.

Auto-Ignition Temperature

If by “ignition temperature” you mean the auto-ignition temperature, LPG typically has an auto-ignition temperature of approximately 410–580°C, depending on its propane/butane composition.
