Gas purification in SNCR denitrification systems

During gas purification, ammonia or a liquefied urea solution is injected directly behind the combustion chamber at a temperature of 900 to 1,100 °C through selective or catalytic reduction. This causes the nitrogen oxides to react with the ammonium compounds and turn into nitrogen and water. This reduces NO_x emissions. The GM700 measures the ammonia slip at the combustion chamber outlet.
