General Electric has announced it will be releasing the 7HA and 9HA air-cooled gas turbines, according to a report from Diesel & Gas Turbine Worldwide. The H-class gas turbine will be released in two versions for the 50 Hz market, the 9HA.01 and 9HA.02, and two versions for the 60 Hz market, the 7HA.01 and 7HA.02.
The first 9HA gas turbine was manufactured in Belfort, France and was transported to Antwerp, Belgium before being shipped to the U.S. for validation testing at GE’s test facility in Greenville, S.C.
According to the article, the 9HA.01 is rated 397 MW and the 9HA.02 is rated 470 MW in a simple-cycle configuration, with each offering more than 41 percent efficiency. In a 1×1 combined-cycle configuration, the 9HA.01 is rated 592 MW and the 9HA.02 is rated 701 MW, with each offering more than 61 percent efficiency.
The report stated the 7HA.01 is rated 275 MW and the 7HA.02 is rated 330 MW in a simple-cycle configuration, with each offering more than 41 percent efficiency. In a 1×1 combined-cycle configuration, the 7HA.01 is rated 405 MW and the 7HA.02 is rated 486 MW, with each offering more than 61 percent efficiency.
GE said the H-class gas turbine incorporates an aerodynamic 14-stage compressor and includes an advanced radial diffuser which, combined with the Dry Low NOx 2.6+Axial Fuel Staged combustion system, allows improved operation of the combustion liner and transition piece cooling.
