Further AGP Solution Expansion

GE advanced gas path extends to 9E, 9F-3 gas turbine fleets; first customer upgrading three Dubai turbines

Posted on November 21, 2013

GE announced the expansion of its advanced gas path (AGP) portfolio to its 9E and 9F-3 gas turbine customers. The company said this technology, which is designed to deliver upgrade performance, marks the first of its kind available for comparably sized gas turbine assets in both classes.

GE said its AGP systems already in operation on GE 7F-3 gas turbines form the basis for the expanded solution. The company said that 97-3 users can expect an output increase up to 6%, a fuel efficiency increase up to 2%, and maintenance intervals as long as 32 000 hours, which extends outage intervals up to 33%. 9E users can expect an output increase up to 3.8%, a fuel efficiency increase up to .9%, and maintenance intervals as long as 32 000 hours or 1300 starts, which extends outage intervals up to 33%, GE said.

Dubai Aluminium (DUBAL), which powers one of the world’s largest aluminium smelters with a 2350 MW power station, is the first GE customer to integrate AGP technology into its installed 9E gas turbines. In April 2013, DUBAL installed the AGP solution on one GE 9E unit and said it has since experienced an output increase of 3.4%, generation of an additional 5.88 MW, and improved fuel efficiency by 1.5%.

Under the same order, DUBAL will upgrade two additional 9E units beginning in November 2013. Across all three units, the site expects to increase its output capacity by approximately 17.64 MW, reduce its fuel use by 1.5% and extend its maintenance intervals out to 32 000 hours, the equivalent of approximately one additional year of operation.

In September, ENKA, which generates more than 13% of electricity for Turkey, placed the first order for GE’s 9F-3 AGP technology for 10 of its gas turbines at the Gebze, Adapazar and ─░zmir power plants. The upgrades are expected to deliver a total of up to 150 additional MW of power.
