Laminar burning speed and flame structure of gas-to-liquid (GTL) fuel has been experimentally measured and analyzed using cylindrical vessel. Since GTL is a mixture of many hydrocarbons, all of the experiments have been done at high temperatures when most constituents have been evaporated. A novel liquid injection system with heating elements have been used to evaporate the liquid fuel before entering to the combustion vessel. Shadowgraph system and a high speed camera that can take up to 40,000 frame per second pictures are set up with the cylindrical vessel to capture the optical recordings of the combustion event. This allows us to observe the flame structure and to investigate the onset of instability.
