Acetylene combustion results in products with a low heat capacity, leading to notably high temperatures in the acetylene flame.
In comparative combustion reactions of equal quantities of acetylene, ethylene, and ethane, acetylene’s complete combustion demands the minimal amount of oxygen and generates the least water.
Consequently, the acetylene flame reaches the highest temperature during combustion, utilizing the least amount of heat for elevating oxygen temperature and for the vaporization of water.
