SNCR - Selective Non-Catalytic Reduction

Through years of experience and knowledge, we have patented innovative technologies designed to reduce nitrogen oxide (NOx) emissions for new or existing coal, oil, and gas fired boilers. Our CCA brand SNCR – Selective Non-Catalytic Reduction systems provide a low cost technique to reduce NOx emissions by 30%-60% for both boilers and lime 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 titling based on furnace temperature, to enhance the NOx reduction performance.
