SCR Systems

Selective Catalytic Reduction

Nitrogen-Oxide Reduction
  • Up to 92% NOx Reduction emissions < 50 mg/Nm3
  • 2 ppm Ammonia Slip
  • 0.5-1% SO2 to SO3 Conversion
General Process
  • Converting NOx into Nitrogen and Water
  • Ammonia is injected into the flue gas stream acting as reductant
  • Static mixers assure homogeneous mixture
  • The mixture flows through catalyst layer placed upstream of the air heater
CFD Analysis
  • All flow devices included
  • All internals <10cm
  • Used to optimize thermal mixing performance
Physical Flow Modeling
  • 1/12th scale model
  • Experience with third-party modeling companies
  • Extensive field verification testing
Modular Construction
  • Handling larger pieces saves time
  • Working at grade instead of at final elevation improves safety
  • Challenges include congested work areas, space for heavy lift cranes, space for modules and laydown

BHI Co., Ltd., the parent company is the licensee of Foster Wheeler’s AQCS including SCR system. BHI FW staffs are very much experienced in FW SCR system for PC Boiler.
