Research on Water Droplet Size Influencing Factors in Watered Fuel Oil Prepared by Mechanical Agitation

Water droplet size of disperse phase of watered fuel oil, which was prepared by a self-made mechanical micro-mixing device, was inspected under optical microscope. The effects of agitation speed, oil temperature and water content on water droplet size were investigated in this research. The experimental results showed that: water droplet size decreases with the increase of agitation speed and oil temperature at 1000-1300 r/min and 60-80°C, respectively. The lower the water content is, the smaller the size of water droplet will be, and the water content is better to be 3-5%.
