摘　　要：综述了高、中、低能量物理场在燃煤烟气脱硫脱硝工艺中的应用。高能量物理场(如高能辐射化学法、微波诱导等离子体法、微波放电法、微波加热法等)通常直接改变脱硫脱硝反应机理;中、低能量物理场包括静电喷射器法、荷电干式喷射器法、磁固定床法、磁流化床法、低温磁性铁基SCR脱硝技术、微波诱导催化还原脱硫脱硝技术等通常改变脱硫脱硝反应的物理过程。烟气脱硫、脱硝效率随物理过程的改进而提高。The application of high - energy physical field, as well as medium - and - low energy physical fields,in coal - fired flue gas desulphurization and denitrification has been summarized up. The high - energy physical fields,such as the high - energy radiation chemical method, the micro - wave induced plasma method, the micro- wave discharging method,and micro- wave heating method etc. , are com- monly used for directly changing the reaction mechanism in desulphurization and denitrification,how- ever,the medium - and - low energy physical fields, including the electrostatic sprayer method, the charge drying sprayer method,the magnetic fixed bed method, the magnetically fluidized bed method, the low - temperature iron - base SCR denitrification technology, and the micro - wave induced catalys- tic reduction desulphurization and denitrification technology etc. ,are commonly used for changing the physical process of desulphurization and denitrification. Along with the modification of physical process,the efficiency of flue gas desulphurization and denitrification can be further enchanced.
