Plasma-Assisted Combustion System Based on Nonsteady-State Gas-Discharge Plasma Torch

This paper describes the experiments with the plasma-assisted combustion system as applied to gaseous hydrocarbons. The system is based on a nonsteady-state gas-discharge plasmatron with a low average current. One of the subjects of the investigations is to elucidate a correlation between the discharge burning regimes in the plasmatron and the properties of the torch flame in the combustion chamber. Depending on the gas-discharge regimes and plasmatron design, the conditions of complete hydrocarbon combustion and partial oxidation have been demonstrated. Aside from that, the data on testing a special power supply intentionally developed for nonsteady discharge powering are presented.
