Pulsation regime of evaporation of water-fuel emulsion droplets

Abstract

This article discusses the existence of the sustainable torch combustion of the reverse type water-fuel emulsions (WFE), previously vaporized in thermochemical reactor (WFE), created on the basis of waste machine and motor oils. The aim is to identify the torch length of the water-emulsion dependence on the water content and temperature in the pretreatment fuel mixture reactor. The paper presents a detailed description of the experimental pretreatment fuel mixture reactor. A technique for obtaining and processing of experimental data is presented. The experimental data in determining the torch length dependence on the reactor temperature and the percentage of water in the water-fuel emulsions are presented. Also the experimental data on the effect of the additional air supply in the thermochemical pretreatment fuel mixture reactor on the height of the torch are presented. Based on this information, the competition of kinetic and hy-drodynamic factors affecting the size of the torches is considered. A comparative analysis of the torches heights of the burning reverse type emulsions, created on the basis of heavy hydrocarbon fuels is reviewed. A possible catalytic action of water vapor on the fuel vapor in the pretreatment fuel mixture reactor is suggested. This effect manifests itself in the fact that the temperature in the thermo-chemical reactor at which the existence of a torch burning water-fuel emulsions is possible, is significantly lower than the temperature for the pure heavy hydrocarbon fuel of technogenic or natural origin (waste oil) .
