GE’s LM2500 gas turbine achieves 75 million combined operating hours

GE (NYSE: GE) today announced that its LM2500 aeroderivative gas turbine family has reached the milestone of 75 million combined operating hours. The LM2500 gas turbine package has been one of the top selling aeroderivative gas turbines in its class for more than 40 years and continues to evolve to provide increased customer value. The current fleet totals more than 2,800 turbines across six continents.

“GE has invested more than 1 billion dollars over the past 40+ years to provide improved reliability and a significant reduction in total cost of ownership for our LM2500 customers, helping to achieve this milestone,” said Dan Kempf, general manager, LM/TM2500 & small gas turbine products for GE. “These units feature 99.7 percent reliability, which combined with their high-efficiency and installation flexibility make the LM2500 family of products ideal for a wide variety of marine, power generation and mechanical drive applications.”

Key features of the LM2500 include full power within 10 minutes, direct drive for 50-hertz and 60-hertz power generation, variable speed for mechanical drive, dual-fuel capability for distillate or natural gas, reduced NOx with DLE (dry low emissions) combustor and natural gas fuel, optional steam or water injection system for NOx emission control, 30 individually replaceable fuel nozzles and reduced maintenance and overhaul intervals with simplified, high-quality modular design and construction.

The LM2500 consists of a 16 or 17-stage axial-flow compressor, annular combustor, two-stage, high-pressure, single-rotor gas turbine and highly efficient six-stage power turbine. A single turbine’s output ranges from 16-34 megawatts (MW) based on configuration and customer requirements. The LM2500 is available as a trailer-mounted generator set, known as the TM2500, which has seen recent success in Egypt, Mexico, Algeria and more. This proven performer's lightweight, compact design allows for quick installation and easy maintenance.

Key Milestones:
•1969 - The first LM2500 gas turbine began operating, powering the U.S. Navy’s GTS Adm. Callaghan cargo ship. To this day, the U.S. Navy continues to select the LM25000 to power the latest surface combatants in its fleet.
•1975-1980 – First offshore platform application; first power generation applications; achieves 1 million operating hours.
•1985 – First cogeneration application; achieves 5 million operating hours; first steam injection system application.
•1990 – Achieves 10 million operating hours; 1,000th turbine delivered; first fast ferry application.
•1991-1995 – Achieves more than 18 million operating hours; development of LM2500+, DLE combustor operational; LM2500+ development test.
•1995-2000 – First LM2500+ shipped.
•2005 – Introduction of the LM2500+G4.
•2009 – 40th anniversary of the LM2500.
•2015 – Achieves 75 million operating hours.
