| 摘 要： | 电子束在烟气中穿透深度和剂量分布将直接影响废气中硫、氮氧化物的脱除效率。通过理论计算和蒙特卡罗模拟计算得到不同能量电子穿过各种厚度加速器箔窗后能量损失情况；对不同入射能量电子束在烟气中透射深度和轨迹分布进行了模拟计算。结果表明：电子束反应最佳能量为700 keV；利用产生1 m长线状束流的电子加速器进行双面照射，烟道反应室横截面最佳尺寸为1.0 m×3.5 m。

| Abstract: | Penetrating depth and dose distribution of electron beam in flue gas can influence efficiency of desulfurization and denitration. Beam energy loss during passing through the metal foil window has been calculated by theory and Monte Carlo simulation. Electron beam penetrating depth and dose distribution in the flue gas irradiation vessel have been obtained as well. Some conclusions have been gotten: the optimal electron beam energy is 700 keV. Cross sectional dimensions of the reaction chamber is selected about 1.0 m×3.5 m. The work mode is face to face irradiation with two electron accelerators. |
