GE introduced its high efficiency H-class gas turbine to the power generation industry in 2002. The steam cooled units have logged 200,000 hours of operation and counting and have proven themselves to be stalwarts within GE’s gas turbine lineup. Now, thanks to advances in technology and shared knowledge from its myriad business units, GE is introducing the 7HA and 9HA air-cooled gas turbines.
“We are offering our air cooled H-class gas turbine in two version 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,” said Vic Abate, President and CEO, Power Generation Products, for GE Power & Water. “The air-cooled H-class gas turbines are designed for cyclic and base-load operation in simple cycle and combined cycle applications.”
In simple cycle configuration, the 9HA.01 is rated 397 MW and the 9HA.02 is rated 470 MW, each at 3000 rpm, offering >41% efficiency. In combined cycle configuration, the 9HA.01 is rated 592 MW and the 9HA.02 is rated 701 MW, each at 3000 rpm, offering >61% efficiency.
In simple cycle configuration the 7HA.01 is rated 275 MW and the7HA.02 is rated 330 MW, each at 3600 rpm, offering >41% efficiency. In combined cycle configuration, the 7HA.01 is rated 813 MW and the 7HA.02 is rated 976 MW, each at 3600 rpm, offering >61% efficiency.
