The paper present experimental results for temperature fields in heterogeneous droplets of liquids, freely falling in a preheated gaseous medium, before their micro-explosive fragmentation. The optical technique of Planar Laser Induced Fluorescence was applied. Unlike the known results of other authors, such fields were obtained for the first time without using holders for droplets, the latter heated in the temperature range of 900?C to 1100?C. The aim was to approach promising gas-vapor-droplet technologies. It is shown that for micro-explosive disintegration of a droplet containing a flammable component (by the example of Diesel and oils of two grades) and water, the necessary and sufficient condition is that the water reaches the boiling point. In this case, local superheating of the inter-component interface is sufficient. Motion intensifies the transformation of droplet and its subsequent destruction with appearance of polydisperse cloud.
