SCR System Engineering
SCRs for Fossil Fuel-fired Boilers and Gas Turbines
Evonik Steag offers a full range of services in SCR design and engineering for both fossil fuel-fired boilers and gas turbines based on 20 years of experience in designing our own systems as well as systems for other operators. As operator engineers we have the ability to apply our own experience in the design and operation of SCR systems to achieve maximum efficiency with minimum costs.

Power plant operational issues involve:
- Achieving the sought NOx removal efficiency while maintaining the desired ammonia slip to minimize the impact on the air heater and the fly ash,
- Protecting the catalyst from large particle ash and its resulting erosion, and
- Planning maintenance and catalyst exchanges around scheduled outages.
Our experience in designing and operating SCR systems for the last 20 years has given us the ability to engineer the SCR and ancillary systems in such a way to control undesirable SCR process reactions and maximizing efficiency.
From the conceptual design phase and component selection, to on-site construction and site management, to start-up and training, and long-term SCR management, Evonik Steag will be on your side to optimize operations and minimize costs.
