Investigation of liquid fuel combustion processes in an electrostatic fieldе

Abstract

Objective. The article presents the results of experimental studies on the effect of a high-potential electrostatic field on the combustion of liquid fuel. Method. Experimental studies were carried out on the developed laboratory installation, which makes it possible to ensure the combustion of liquid fuel in a high-potential electrostatic field with the possibility of changing the polarity. The change in the polarity of the applied voltage to the electrode system of the experimental setup led to an increase in the fuel burning rate in the first case, and to its attenuation in the second.Result. In this paper, studies have been carried out proving the effect of an electrostatic field on the burning rate and reducing the content of harmful components (soot and carbon monoxide) in fuel combustion purges. Based on the values of the fuel burning rate obtained as a result of the experiments, graphic dependences were constructed on the applied voltage, on which the areas of linear and non-linear changes in the combustion parameters were identified.Conclusion. The results of the research carried out can be used to create new highly efficient burners for liquid fuel boilers. The effect of reducing the burning rate can be used to create fire safety devices that block the spread of flame during a fire.
