Abstract

The laminar burning velocity of ethanol premixed combustion enriched with liquefied petroleum gas (LPG) has been studied experimentally. The study was conducted in a cylindrical combustion chamber, and combustion model was spherically expanding flame. The results showed that the laminar burning velocity of ethanol enriched with 5–10% LPG is higher than that of pure ethanol and that of pure LPG. This is due to the formation of H and OH radicals in the preheating zone, where the reaction occurs to form H₂O and release heat. It raises temperature in the preheating zone which contributes to increase in the laminar burning velocity.
