Recently, in order to improve energy translation effect and decrease the emission of combustion byproducts, many researchers have gradually paid attention to enhance combustion and control combustion flame by utilizing an electric field. The effect of different electric fields, such as vertical electric field, horizontal (or radial) electric field, scattered (viz single electrode) electric field, and alternation electric field, etc, on various fuel combustion flame characters were firstly discussed. Secondly, the feasibility for decreasing combustion byproducts by using the electric field was described. Finally, up to now, the complete research on the relation between different electric fields and the combustion flame characters does not exist. Its relative base data, perfect mechanism analysis, and combustion reaction dynamics with electric field are lack of. Enhancing combustion and controlling combustion flame by utilizing various electric fields possesses the practical significance for saving energy and reducing emission.
