Boiler upgrade for emissions reduction | GE Steam Power

We can help you achieve a secondary reduction of up to 30% of NOx with a selective non-catalytic converter (SNCR) system. This works by injecting urea or ammonia in the upper part of the furnace. At temperatures of 1,500 to 2,010 °F the NOx is reduced without the need for a catalyst. The GE Umbrella-SNCR (U-SNCR) is unique because the urea is
