Resumo

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.
