Characteristics of Film Evaporation for Homogeneous Charge Preparation of Typical Fuels

Fuel films of several typical fuels were investigated by means of thermal gravity analysis (TGA). To make diesel homogeneous charge by means of film evaporation, it was concluded that to get 30%∼50% evaporation of film, the wall temperature should be set between 150°C and 180°C for diesel and 40°C∼60°C for gasoline, and to get 95% evaporation of film, the wall temperature should be set between 200°C and 250°C for diesel and 50°C∼100°C for gasoline, when the thickness of the fuel film is about 40 μ m. Based on the properties of fuels, the evaporation characteristics of diesel under 100°C should be improved.
