Peculiarities of Plasma Assisted Stearine Combustion

During combustion of hydrocarbons with high viscosity there is a problem of their spraying. Traditional gasdynamic jets are not suitable for solving these problems. Therefore, the creation of new plasma-liquid systems that would allow effective spray hydrocarbons with high viscosity is an important and promising direction. Plasma assisted combustion of hydrocarbons with high viscosity was investigated in this work. Plasma jet was used for spraying of high viscosity hydrocarbons. The mixture of n-paraffin and stearine in the solid state is used as the model of the solid paraffin based fuel. Plasma source was rotational gliding arc. Plasma system consisted of the area where the plasma is formed, the area where plasma injected with hydrocarbons and the area with flame. The current-voltage characteristics of the rotational gliding arc discharge were measured. Diagnostics of plasma torch and the flame was carried by emission spectroscopy. Temperature in the flame during plasma assisted combustion of hydrocarbons was measured.
