Selective Non-Catalytic Reduction (SNCR)

Selective Non-Catalytic Reduction (SNCR)

Peerless Emissions Control

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.

Selective Catalytic Reduction (SCR) – Peerless Emissions Control

Selective Catalytic Reduction (SCR) – Peerless Emissions Control

Peerless Emissions Control

As flue gases are combusted in gas turbines and process furnaces, nitrogen oxide (NOx) is formed. Our Selective Catalytic Reduction (SCR) system is a post-combustion NOx control technology, which injects an ammonia (NH3) based reagent into the flue stream to reduce NOx emissions by up to 95%.

Peerless Emissions Control patented Direct Injection SCR System is an innovative delivery, metering and injection system designed to reduce NOx and CO emissions using substantially less auxiliary load compared to a traditional SCR system.

Our Peerless Emissions Control brand TRIM-NOx® XL SCR injection module automatically injects a urea or ammonia-based reagent into the exhaust gas of a boiler, furnace, turbine or IC engine to reduce NOx emissions. Each module is engineered to optimize efficiency, performance and reliability while meeting stringent environmental standards.

Our SCR designs are engineered to optimize efficiency, performance and reliability, while meeting stringent energy standards. They are adaptable for a wide range of temperatures, exhaust flow conditions, and various types of fuel including:
