Selective Catalytic Reduction Systems

We have supplied over 130 selective catalytic reduction (SCR) systems globally for a variety of applications from large-scale pulverized-coal utility boilers, through industrial process heaters and boilers, to combustion turbines. In fact, we supplied the first four SCR systems on utility plants in the United States.

As a boiler manufacturer, we can assess the operational impacts of an SCR installation including modified flue ducting, economizer bypass and fan impacts. And as a construction, engineering and equipment company we can supply the complete SCR system on a turnkey basis.

Ammonia injection is a critical component in a successful SCR installation. We have supplied all types of systems ranging from anhydrous ammonia, aqueous ammonia and urea systems. Our injection grids are designed and installed for optimum distribution with minimal pressure loss and virtually no maintenance. Our professionals apply the latest research, design, engineering, construction and management resources to provide single-source project execution. We know which catalyst to use for which fuel, boiler type, and NOx reduction target. "We selected Foster Wheeler's state-of-the-art SCR systems for our Petersburg generating station. Foster Wheeler's modular design and unique heavy lift skills proved the right innovative solutions for the project's complex construction needs. All project goals were exceeded, and safety performance, in particular, set a new standard for complex projects of this type." David Kehres, NOx Program Manager, Indianapolis Power and Light Company
