CCA Combustion Systems

CCA's core expertise is emissinos technologies for gaseous, liquids and solid fuels, including combustioon and post combustion NOx controls.  CCA offers burners and burner upgrades for coal, oil, and gas-fired systems, new burners, overfire air (OFA), flue gas recirculation (FGR), targeted water tempering, SNCR, and SCR.  Technologies can be implemented alone or in combination to achieve high levels of NOx control.

 


 

Low NOx Burners   

Our CCA brand low-NOx burners (LNB) are configured to stabilize the combustion process and allow the unit to be operated at lower excess O2 by utilizing a flame stabilizer. To enhance the NOx reduction capabilities, the flame stabilizer is designed with internal air/fuel staging. This sets up fuel-rich and lean zones downstream of the stabilizer in the primary combustion zone where the majority of the NOx emissions are formed, providing additional staging, flame stability and lower NOx emissions.

Selective Non-Catalytic Reduction (SNCR)       

Our CCA brand Selective Non-Catalytic Reduction (SNCR) 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.

 

Trim-NOx XL SCR Injection Module       


Our CCA brand TRIM-NOX® XL SCR Injection system automatically injects a urea or ammonia based reagent into the exhaust gas of fuel oil or natural gas boilers, furnaces, or turbines to reduce NOx emissions. Each module is engineered to optimize efficiency, performance and reliability, while meeting stringent environmental standards.

 

Overfire Air (OFA)     

Overfire Air (OFA) systems divert a portion of the combustion air away from the primary combustion zone. Our CCA Combustion Systems brand Overfire Air system, deeply stages combustion for enhanced nitrogen oxide (NOx) reduction. By utilizing a unique port design to ensure advantageous air and fuel mixing, our OFA system can minimize NOx, achieving 30-40% reductions beyond low NOx burners.

 

Flue Gas Recircultionn (FGR)

Flue Gas Recirculation (FGR) is a powerful nitrogen oxide (NOx) control technique that significantly reduces NOx emissions by recirculating flue gases from the boiler exhaust duct into the main combustion chamber. This process reduces peak flame temperature and lowers the percentage of oxygen in the combustion air/flue gas mixture, thereby reducing thermal NOx formation.

 

Combustion Tempering (CT)

Our CCA Combustion Systems brand Combustion Tempering (CT) process injects water (steam or flue gas can be utilized) upstream of the flame to reduce the temperature at the point of initial combustion, reducing NOx emissions. By utilizing computational fluid dynamics (CFD) modeling and laser Doppler spray testing, we are able to deliver optimal reliability, efficiency and operations, minimizing water usage and ensuring consistent performance for your specific needs.

Rich Reagent Injection (RRI)

The Rich Reagent Injection is a technology designed to reduce NOx emissions. The RRI process utilizes a reagent (urea) that is injected into the fuel-rich regions of the furnace to chemically reduce NOx formed by the combustion process.
