NOx
Sargent & Lundy provides engineering services for the full-scale design of both combustion and post-combustion technologies on a full range of coal- and gas-fired power plants.
Combustion
We're experienced with all applicable combustion technologies to reduce NOx emissions for specific fuels and furnace designs. These include:
- First-generation and second-generation low NOx burners (LNB)
- Overfire-air-injection systems
- Flue gas recirculation systems
- All types of reburning (coal and gas) technologies
- Process optimization software
- Combinations of these technologies
Post Combustion
We also have extensive experience providing engineering services for the full-scale design of post-combustion technologies, including selective catalytic and non-catalytic reduction (SCR and SNCR). We have been awarded detailed conceptual designs for more than 200 SCR retrofits, the majority of which are on large coal-fired utility plants. We are very familiar with the respective suppliers, their strengths and differences, cost of materials, and manufacturing schedules.
