Experimental study was carried out on the enhanced vaporization process of fuel under vacuum condition.Fuel was ejected from the nozzle in a visual vacuum vessel.The droplet crushing and vaporization characteristic parameters such as the liquid droplet size distribution, the gas-liquid phase morphological development, and the vaporization speed were obtained under different injection pressures.The experimental results show that the crushing of liquid droplets and the vaporization of fuel were mutually reinforced.At the injection pressure of 5 MPa, most of the droplet sizes are within the range of 5 μm, and within 2 ms the fuel nearly reaches equilibrium and reaches 85% of equilibrium vaporization capacity.When this enhanced vaporization technology is used in atmospheric and vacuum distillation processes, the yield of light oil will increase.
