Economizer Hoppers | Airflow Sciences Corporation

An often neglected part of a plant, the economizer hopper is intended to capture large particles before they exit the boiler. If the plant has an SCR, the economizer hopper plays a huge role in LPA (large particle ash) capture.But plants without SCRs need economizer hoppers to capture ash that can plug air heaters or end up in the windbox.
