Abstract:

Based on the operation data, including selective catalyst reduction (SCR) system inlet NOx mass density, oxygen content, denitration efficiency, flue gas flow rate, ammonia injection rate and others, monitored by realtime mornitoring system, a few of calculation models were built to verify denitration operation and set alarm value. Establishment of denitration alarm system will help power plant to adjust in time.

Key words:

SCR system, real time monitoring system, operation improvement
