GE’s new 7HA class turbine offers more power
GE announced the launch October 2 of the latest in its HA gas turbine line, the 7HA.03, which will power Florida Power & Light Company’s (FPL) Dania Beach Clean Energy Center near Fort Lauderdale, Florida.
The 7HA.03 provides greater capacity and efficiency: offering 134 more megawatts than GE’s 7HA.02 gas turbine (2x1 CC), and an increase in efficiency by 0.4 percent. The 7HA.03 turbine claims over 64% net combined cycle efficiency. The company also claims enhanced flexibility, and lower capital costs and installation time.
New design features, pulled from other HA designs, include a larger titanium R1 blade that enables greater airflow and output, while the adoption of GE’s DLN 2.6e combustion system—the first of its kind on a GE 60-hertz gas turbine—offers higher firing temperatures while maintaining emissions compliance. The ability to turn down to 30% load while still in emissions compliance, when combined with an improved ramp rate of 75 megawatts per minute — 15 megawatts more than the 7HA.02 — will enhance power plant operators’ ability to rapidly respond to market and grid conditions.
