Flames contain electrons as well as positive and negative ions, which makes them electrically conductive. When a flame is placed within an electric field, these charged particles are either attracted or repelled by the field.1
This interaction distorts the flame, a phenomenon often described as a mechanical effect known as electric wind. By altering the shape of the flame, the electric field can subsequently influence the burning velocity of the combustion process.1
