RESEARCH ON REMOVING CO₂ FROM COAL-COMBUSTION EXHAUST FLUE GAS BY HIGH-VOLTAGE NARROW PULSED CORONA DISCHARGE

The authors, with the real flue gas generated in a coal-burning stove, carries out a research on the laws and the affecting factors of the removal of CO₂ by the non-equilibrium plasma in pulsed corona discharges. Both of positive and negative pulsed corona discharges have notable function for the removal of CO₂ and CO by dissociation, with the removal efficiencies of both more than 20%. The energy consumption of flue gas treatment is 6.01×10⁻³ kWh/Nm³, the energy yield of CO₂ removal is 4.55×10³g CO₂/kWh. The recombination dissociation processes are considered as the main process of the CO₂ and CO removals.
