Measures of reducing measurement failure rate of continuous emission monitoring system for selective catalytic reduction denitrification flue gas

Abstract

Abstract:

Abstract:At the initial operation stage of continuous emission monitoring system (CEMS) for selective catalytic reduction (SCR) denitrification flue gas in Anhui Huadian Suzhou Power Generation Company Limited, measurement faults occurred frequently, which affected the reliability of online flue gas monitoring, made the operation adjustment difficult and increased the maintenance work amounts. This paper analyzed the measuring principles of CEMS, summarized the common faults and their treatment measures of CEMS, and proposed some prevention measures. After adopting a series of measures, the measurement failure rates of NOx and NH3 of CEMS were effectively decreased.

Key words:

Keywords:denitrification, selective catalytic reduction, continuous emission monitoring system of flue gas, NOx, NH3, measurement, failure rate
