Issue 8 and Volume 103.

GE’s fleet of F technology gas turbines has passed 2 million hours of commercial operation in power plants around the world, according to GE Power Systems records. To date, 133 GE F machines are operating in 15 countries and the company has received more than 400 orders and commitments for the turbines since they were introduced in 1986. GE picked up orders for 84 F turbines in 1998, many for the booming United States market.

The turbines have a net thermal efficiency of 55 to 57 percent in combined-cycle applications.

The first F technology unit installed was a repowering application at Virginia Power’s Chesterfield station. This fleet leader has now accumulated more than 47,000 fired hours. The largest F technology installation is at Korea Electric Power Corp.’s Seoinchon combined-cycle plant, where 16 7FA turbines have been installed in Blocks 1 through 4. The total plant output of 4,000 MW makes it the world’s largest combined-cycle facility.
