【摘要】：随着社会的发展,我国对氮氧化物的排放量做了严格的规定,除了采用低NO_x燃烧器外,燃煤电厂烟气脱硝系统也不断增加。根据目前较流行的还原剂选择方法,对尿素区水解系统和SCR区的控制系统及仪表设定进行了分析,对整个脱硝系统进行了全面的介绍,对今后燃煤电厂脱硝系统仪控设计提出了一些建议。
[Abstract]:With the development of the society, the emission of nitrogen oxides is strictly regulated in China. In addition to the low NO_x burner, the flue gas denitrification system of coal-fired power plants is also increasing. According to the popular reducing agent selection method, the control system and the instrument setting of the urea zone and SCR area are analyzed and the whole denitrification system is made. A comprehensive introduction is made, and some suggestions on the design of the instrument and control system for the denitration system of coal-fired power plants in the future are put forward.
