Pollution Solution
Pollution control projects generally consist of retrofitting existing facilities with state of the art pollution control system to bring the air emissions of existing generating facilities into compliance with current air quality standards. Typical projects vary from fly ash reduction projects for solid fuel generating facilities to bag house SCR and precipitator retrofits.
Brayton Point Power Station
- Customer:Dominion Energy Brayton Point, LLC
- Location:Somerset, Massachusetts
- EPC Contractor:Gemma Power Systems, LLC
- Design Engineer:Progress Materials Inc. / ESI of Tennessee, Inc.
The Ash Reduction Project (ARP) consists of a fluidized bed combustor facility which processes 42 tons of high carbon feed fly ash per hour. The ARP reduces the feed fly ash carbon content allowing the resultant product fly ash to be marketed as a concrete constituent.
Gemma’s scope of work includes the complete engineering, procurement, construction, start-up and commissioning of the project facilities, which include in addition to the combustor facility, a 164’ diameter product ash storage dome, a remote truck load-out station, and extensive interconnects to the existing plant.
Construction began February 2005 and was completed July 2006.
