摘  要:介绍了选择性非催化还原脱硝技术的原理和反应机理,阐述了H2、碳氢化合物、过氧化氢、氧化性有机化合物(如醇类)、一氧化碳等添加剂作用于SNCR的影响和脱硝机理,通过提高系统内H、O、OH以及CHi活性基的数量,启动低温区域NO的还原,从而使反应温度窗口向低温方向移动,提高低温脱硝效率。通过了解添加剂的作用特点和反应机理,进一步为开发经济节能的新型高效添加剂奠定基础。The principle and reaction mechanism of selective non-catalytic reduction denitration technology are introduced.The effects of additives such as H2,hydrocarbons,hydrogen peroxide,oxidizing organic compounds(such as alcohols)and carbon monoxide on SNCR and the denitrification mechanism are expounded.By increasing the number of H,O,OH and CHi active groups in the system,the reduction of NO in the low temperature region is started,so that the reaction temperature window moves to the low temperature direction and the low temperature denitrification efficiency is improved.By understanding the action characteristics and reaction mechanism of additives,it will further lay the foundation for developing new and efficient additives that are economical and energy-saving.
