Ash Handling System Conversion

Mechanical/Structural Installation of Ash Processing Equipment for a Coal-Fired Power Plant

Mechanical | Structural Steel | Electrical | Instrumentation & Controls

The main objective was to convert an existing ‘wet’ sluicing system to a dry handling system using a dry flight conveyor, large bore ash piping, and new fly ash processing equipment. 

The scope of the project included mechanical conveying, mechanical piping, structural steel, concrete, and E & IC disciplines, such as installation of: 

  • Drag chain conveyor below the economizer including air piping 

  • Structural support steel and access platforms for new drag chain conveyor 

  • Large bore ash convey piping in existing pipe rack structure 

  • New control panels for ash handling system including VFD control panel and mechanical separator control panel 

  • New PLC hardware and modifications to existing control system hardware 

  • Interior work was completed in phases during manufacturing down days.

SEFA organized and successfully completed critical lifts over 22,000 lbs. and over 100’ high utilizing a 250-ton crane.
