EPISODE 59 - Restoring SCR Performance at Apex Four Corners Power Station

A case study outlining performance challenges at the 1040 MW Apex Four Corners coal-fired power station, where ash buildup, failed LPA screens, and degraded air cannon systems led to rising differential pressure, reduced output, and catalyst damage within the SCR system. The study explores the operational impact of ineffective cleaning and component failure, highlighting how these issues increased maintenance demand, safety risks, and emission compliance pressure over time. PHL
