Abstract： In order to solve the problem of timely adjustment of ammonia-nitrogen ratio in SCR denitrification reactor， zonal ammonia injection control technology has been widely used in recent years. First of all， this paper will introduce the three components of the zonal ammonia injection control technology， and analyze the application status and selection basis of the measurement technology in detail， in order to clarify the purpose and principle of the three-layer control technology. Finally， an in-depth analysis will be made to the application conditions of the zonal ammonia injection control technology.

Keywords： SCR denitrification; zonal ammonia injection; ammonia-nitrogen ratio; electrochemical method; Chemiluminescence Method
