Which Is Higher: The Temperature of Acetylene or Liquefied Gas

Acetylene flames are characterized by their high temperatures.

During combustion, acetylene produces intense heat, with oxy-acetylene flame temperatures reaching approximately 3200°C. This makes it ideal for applications such as metal cutting and welding. Acetylene, chemically represented as C2H2 and also known as carbide gas, is the smallest member of the alkyne series. It is predominantly utilized in industrial settings, particularly for welding metals.

The flame temperature of liquefied petroleum gas (LPG) with oxygen is nearly 2000°C, indicating that LPG flames are cooler compared to acetylene flames.
