Centrifugal Fan Applications for SCR Systems

Power plants and other industrial operations that involve combustion often use Selective Catalytic Reduction (SCR) systems for pollution control and environmental compliance. SCR systems pull flue gas out of the gas stream and inject it with a reagent (usually Ammonia or Urea) to reduce Nitrogen Oxide (NOx ) levels before exhausting to the atmosphere. SCR systems are a critical part of meeting acceptable emissions levels put forth by the Environmental Protection Agency (EPA).

Story: The following high temperature fan was built for a power company in Colorado. Several years ago, the customer had purchased a Selective Catalytic Reduction (SCR) system with fans provided by a competitor. What followed was a continuous string of unresolved bearing failures that resulted in unreliable performance and unacceptable maintenance costs. Finally, AirPro was called in to review the application and offer a solution.
