POSSIBILITY OF WATER-OIL EMULSION COMBUSTION

Abstract

The article describes a device developed by the authors for wave treatment of water-oil emulsion for preparation of water-oil emulsion for combustion. High efficiency of hydrocarbon fuel combustion is one of the main indicators when choosing a method of fuel mixture preparation. The scheme of an innovative vortex burner for combustion of water-oil emulsion is presented. A review of existing equipment for preparation of high quality emulsion is made. The necessity of forced oil dehydration for high quality combustion in burners is refuted. The choice of material for the dispersant body with regard to corrosion, cavitation and wear resistance requirements is presented. The analysis was carried out in order to reveal the relations of transformation of physical-chemical properties of water-oil emulsion (sedimentation and aggregative stability, structural viscosity) from temperature and from the volume of water in them. Knowledge of these physical-chemical parameters is essential to ensure the efficiency of atomization and stable combustion of the fuel under study. A methodology for determining the dynamic viscosity using a capillary viscometer with results obtained in different ranges of temperature changes of emulsified fuel preparation is presented. Data on the density of oil-water emulsion as a function of water concentration at 70 °C was obtained. The dependence of stability of emulsion based on fuel oil M-100 from settling time at 20 °C has been analysed. When using wave treatment dispersant, stable water-oil emulsions are obtained, suitable for use in power engineering as fuel.
