The Combustion Turbine Operations Technical Forum (CTOTF) Annual CTOTF/POWER Innovation Excellence awards 2020
Operational Excellence Winner
In the operations category, Exelon’s Mystic Generating Station in Charlestown, Massachusetts, was recognized for successful windscreen projects completed on its Units 8 and 9 air-cooled condensers (ACCs). According to Plant Manager Brian Pettenati, the projects were necessary to ensure the units could reliably operate at maximum capacity during the summer.
“On hot, windy days, we had to de-rate the units due to a reduction in ACC efficiency” Pettenati explained. “We needed something that would stop hot air from recirculating from the top of the ACC back to the suction of the fans, and we wanted to eliminate the wind-tunnel effect under the ACC, which tended to stall the natural air flow to the fans.”
Pettenati asked Mike Brown, Exelon’s technical manager for the Northeast region, to find a solution. Brown tasked Ying Ng, senior site engineer, with managing the project. Ng did some digging and identified a windscreen solution offered by UK-based Galebreaker Industrial. So, Galebreaker and its subcontractor, Ergon Research, were brought in to study the Mystic site.
