摘要(Abstract):
大型火电机组的氮氧化物排放已受到多方关注,分析了SCR(选择性催化还原)脱硝系统存在测量和控制策略方面的问题,根据SCR脱硝的原理和工艺流程提出了优化措施,提高了脱硝系统运行的可靠性,已取得较好效果。
NO_X emission of large thermal power generating units has been brought into sharp focus. The paper analyzes problems in measurement and control strategy of SCR(selective catalytic reduction) denitration system and presents some optimization and improvement measures in accordance with the principle and technical process of SCR denitration system. With the implementation of the measures, favorable effect has been achieved, and operation reliability of denitration system is improved.
