Optimising DeNOx plants with the SICK In-Situ solution
In some countries, the limit values for NOx emissions are so low that even power plants that utilize relative clean fuels like natural gas need to implement additional processes. This includes Selective Catalytic Reduction (SCR), which can further reduce the NOx emissions to ensure the permissible emission limits are adhered to.
In this case it is also necessary to monitor the DeNOx systems to guarantee their proper performance. The gas conditions include high dust and high temperature, so analyzer/probe installation location is critical.
SICK In-situ solution for SCR DENOX measurement:
▸NOx and O2 measurement at SCR Inlet & Outlet to calculate removal efficiency.
▸NH3, Ammonia measurement at SCR Outlet to ensure 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.
