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

Published on: 

GE recently announced that its LM2500 aeroderivative gas turbines have completed 75 million combined operating hours. The current fleet totals more than 2,800 turbines across six continents.



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 MW and is available as a trailer-mounted generator set or TM2500. Its lightweight, compact design allows for quick installation and easy maintenance.


The LM2500 attains full power within 10 minutes, and features 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 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.


Dan Kempf, general manager, LM/TM2500 & small gas turbine products for GE said the company has invested more than 1 billion dollars over the past 40+ years. “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.”
