Exhaust frame upgrade
The more robust exhaust frame upgrade evolves operational flexibility and boosts reliability. Protecting F class units during turndown and peaking helps reduce downtime linked to exhaust liner degradation.
What can upgrading do for you?
The more robust exhaust frame is mission-built to address exhaust liner degradation from more frequent cycling of 7F and 9F plants. This upgrade helps reduce O&M costs and downtime caused by excessive wear and tear of the existing liner.
7F and 9F plants can yield significant availability and reliability through reduction of unplanned outage risk and benefit from shortened outage time with reduced scope of repairs.
The more robust exhaust frame is a key hardware enabler for future enhanced turndown solutions.2 The upgrade is a true step forward in the evolution of 7F and 9F gas turbine plants, helping to ensure flexibility to respond to changing demands on future plant operations.
How we get you there
Bringing the advantage of OEM data and product expertise, this upgrade is based on extensive fleet experience. It features advanced exhaust frame technology tested and proven in 7F.05, 7HA and 9HA technology. The exhaust frame solution modernizes gas turbine exhaust systems to match today’s energy sector's demands, adding flexibility to manage increased cyclical peak demands that future energy operators will require.
Reliability improvements have been made across the exhaust frame and exhaust frame liner. Hardware improvements—and software that incorporates both 7F.05 and HA technology—have been proven during 19,000+ hours in operation and 1,050+ successful starts of the more robust exhaust frames sold and installed. Operators have seen turbine wheel temperature reduction of 15-90˚F.3
With 90+ 7F.05, 7HA, and 9HA gas turbines in commercial operation, the solutions technology has accumulated 1.5M+ operating hours
of field experience to help meet the cyclical peak demands of a volatile power market.
