Abstract

In order to detect the performance of SCR denitration catalyst activity online, and optimize the AIG spray distribution automatically, an innovative system is proposed. The system could monitor the NOx concentration distributions of SCR inlet and outlet flues simultaneously. According to the distributions of NOx concentration and flue gas flow rate, the performance of SCR denitration catalyst could be detected. After the analysis of parameters, DCS could adjust the automatic regulating valve to optimize the AIG spray distribution. An optimal NOx concentration distribution of SCR outlet flue will be realized, which lead to the minimal NH3 consumption and escape concentration. With the proposed system, the working condition of SCR system could be optimized automatically. Better economic and environmental indicators can be received for coal-fired power plants.
