| 摘 要： | 脉冲放电脱除ＮＯ和ＮＯｘ（ＮＯ＋ＮＯ２）的实验表明，烟气中的飞灰对ＮＯｘ具有２％－４％的吸附脱除作用，对脉冲放电又有抑制作用，使ＮＯ和ＮＯｘ脱除具有降低的趋势，增加烟气含水量增强了飞灰粒子表面的化学吸附能力，使得在烟气含水量为１５％和单位体积烟气注入能量小于３Ｗ．ｈ／Ｎ，＾３时，ＮＯ和ＮＯｘ脱除率提高５％－１５％。

| Abstract: | The removal of NO and NOx from flue gas was investigated experimentally using a pulsed corona discharge.The results showed that flyash in flue gas not only removes NO and NOx about 2% 4% by adsorption, but restrains the pulsed coral na discharge and induces a trend of the decreasing removal efficiency of NO and NOx. Increasing the content of H2O in flue gas enhances the chemical adsorption of flyash particle surface and when the water vapor content of 15% (V/V) of flue gas and energy consumption of 3 Wb/Nm2 removal efficiency for NO and NOx were raised to 5 % 15%. At the conditions of the residence time ofs. o s for the nue gas in reactor and specific energy of 4 Wh/Nm3, the removal efficiency of NO and NOx are 42% and 29% respectively. |
