Economizer outlet, selective catalytic reduction (SCR) inlet

The gas conditions include high dust and high temperature, so analyzer/probe installation location is critical. NOx and O2 are measured at the inlet and outlet of the SCR to calculate removal efficiency. Ammonia is monitored on the outlet to insure that NH3 slip is low to meet emission limits and to limit contamination. SICK offers in-situ gas analyzers GM32, GM700 and ZIRKOR200 to measure all of these key parameters.
