SNCR systems provide a low-cost technique to reduce NOx emissions by 30%–75% for boilers, furnaces and kilns.
The SNCR process involves injecting a reagent into the flue gas in the appropriate temperature window. The reagent reacts with NOx to form harmless nitrogen and water. The design, arrangement, and location of the reagent injectors are critical to the performance of the SNCR system. Our advanced technology utilizes variable droplet size control and automatic tilting injectors based on furnace temperature, to enhance the NOx reduction performance.
SNCR System Package
Our SNCR systems include reagent storage tanks, pumping and flow control, reagent injection systems, and a boiler control interface. CCA also provides experienced field engineers for optimizing the SNCR in conjunction with the combustion system and overall operations.
