【Abstract】 Charged dry type calcium-sprayed desulfurization technology by plasma is based on combination of the plasma and traditional dry type calcium-sprayed desulfurization technology. The influence of the operation parameters on SO₂ removal rate with a pulsed corona discharge was studied to promote the industrial application of this technology.The flow rate of the flue gas was 100 m³/h-300 m³/h.The SO₂ removal rate reached 80%.The range of SO₂ concentration in flue gas was 1 000 mL/m³-2 000mL/m³.The flue temperature was 60 ℃-80 ℃.The molecule ratio of CaO to SO₂ was 2. The energy consumption was 3 （W·h）/m³-5 （W·h）/m³.The wire-cylinder electrode structure and a positive high voltage pulse power supply were used in the experiment.更多还原
