摘要
介绍了华润某电厂660MW级超超临界火电机组针对SCR脱硝控制在超洁净排放新控制指标下所做的控制优化改进,通过优化,成功克服SCR脱硝控制的大延迟、大惯性,使机组氮氧化物排放在全负荷运行中始终处于要求控制指标以下。
This paper introduces a power plant of CRP which has 660MW ultra supercritical thermal power unit. According to the new control index of ultra clean emission, the optimization of SCR denitriflcation control is improved, the large delay and great inertia of SCR denitrification control have been successfully overcome through the optimization, the nitrogen oxides of the unit are always under the control target in full load operation.
