摘要: 为优化大型工业电子束脱硫脱硝装置和配套大功率电子加速器工程参数，应用Geant4模拟分析了不同出射能量的单能电子束在烟气中的径迹和偏转后电子束在烟气中的等效剂量场。计算得到1.75 MeV电子束更符合1 000 MWe级火电机组烟气系统工程设计需要，计算结果将为工业化设计提供参考。

Abstract: In an electron beam irradiation flue gas desulfurization and denitrification technical model, the track and the equivalent dose field of electron beams with different inject energy were simulated with Geant4 toolkit. Simulation results show that electron beam with 1.75 MeV matches with 1 000 MWe level power plant flue gas desulfurization and denitrification technical design. The simulation results will be beneficial to the engineering design and the accelerator parameter optimization.
