The temperature of oxy-acetylene flame is around

Solution (By Examveda Team)

The oxy-acetylene flame is generated by burning acetylene (C₂H₂) in the presence of oxygen (O₂), creating one of the hottest known flame types used in industrial applications.

When acetylene combusts in oxygen, it undergoes a chemical reaction that releases a significant amount of heat:

C₂H₂ + 2.5O₂ → 2CO₂ + H₂O + Heat

This combustion produces a flame with two distinct zones: an inner cone and an outer envelope. The inner cone is the hottest part and is typically used for welding and cutting purposes.

The temperature of the inner cone in a neutral oxy-acetylene flame (balanced oxygen and acetylene) reaches approximately 3600°C (about 6530°F).

Such a high temperature is ideal for melting most metals, including steel and iron, which makes the flame extremely valuable in metalworking industries.

The flame can be adjusted to three types depending on the oxygen-to-acetylene ratio:

Neutral Flame: Equal oxygen and acetylene; used for welding most metals.

Carburizing (Reducing) Flame: Excess acetylene; used for specific applications like welding high-carbon steels.

Oxidizing Flame: Excess oxygen; used for cutting metals.

Among these, the neutral flame produces the highest and most efficient heat, reaching up to 3600°C.

Therefore, the correct answer is 3600°C (Option C).
