Selective Catalytic Reduction Systems

Selective Catalytic Reduction
Riley Power Inc. (RPI) and its sister company, Babcock Power Environmental Inc. (BPEI), offer complete integrated Selective Catalytic Reduction (SCR) systems for any OEM. Our projects encompass Computational Fluid Dynamics (CFD) and physical modeling, ductwork, reactors, support steel, initial catalyst charge, fans, complete reagent loading, storage, injection systems, startup, testing and training, and a full range of guarantees.

Fuel Type Experience
Our vast experience with a wide range of fossil fuels at various sulfur contents includes Bituminous, Lignite, and PRB coals along with petroleum coke blends, oil and gas. Our designs are fully integrated with the boiler system to ensure seamless operations.

Delta Wing® Technology
Successful SCR systems require a homogeneous NO_X/NH₃ mixture, consistent temperature, and uniform flow distribution. Riley Power consistently achieves all of these criteria along with reducing ammonia/urea consumption (slip) and eliminating air heater plugging. The Delta Wing® Technology provides homogeneous gas mixing and reagent injection in one application with no moving parts in the gas stream. This mixing technology requires minimum tuning during startup and commissioning and little, if any, annual “tuning” of operating SCR systems. The usual duration of initial commissioning from cold start of operation to consistent full load operation is less than two weeks. This process enables our customers to quickly reach guaranteed NOx reductions, often greater than 90%, and operate consistently over the full load range.
