Selective Non-Catalytic Reduction

Steag Energy Services (formerly ESA) offers SNCR systems that are economical, cost-effective and suited to a range of NOx compliance strategies. Our SNCR experience includes the following:

• 15-600 MW Units
• Coal and Biomass Fired
• Single or Multiple Injection Zones
• Baseline, Startup and Optimization Testing
• CFD Process Modeling

Steag Energy Services (formerly ESA) has installed SNCR systems with a wide range of detail and complexity based on our clients needs. From systems using stationary injectors and existing boiler penetrations to systems with automated retractable injectors and multiple injection zones, Steag Energy Services (formerly ESA) can design a system to meet a variety of needs. Most importantly, Steag Energy Services (formerly ESA) understands the need to balance system cost with incremental NOx benefit.

• Simple system design with few boiler modifications requiring low capital cost.
• Can be used with other NOx control technologies to achieve further reductions.
• Can be used as first stage to hybrid SNCR/SCR system to reduce catalyst size, capital cost and operating costs.
• Capable of significant NOx reductions depending on application.
