Research of the treatment of flue gas desulfurization by gliding arc discharge plasma in thermal power plants

Thermal power generation process will generate a lot of sulfur emissions, which will produce acid rain pollution. Gliding arc discharge is a new pollution control technology for FGD. In this study, SO₂ is selected as the research object, the impact of different discharge status on treatment effect is studied by changing the experimental conditions such as discharge power, flow rate of mixed gas, initial concentration of SO₂ and relative humidity etc. The results showed that the SO₂ removal increases as the discharge power and relative humidity increase, and it reduces as the gas flow rate decreases; the higher the initial concentration, the lower the removal efficiency, but the increase in processing amount per unit time, the energy utilization. But the energy efficiency improves with the increase of process amount per unit time.
