GE LM2500 - Aeroderivative Gas Turbine for Marine and Industrial Applications
The LM2500 gas turbine is made up of a single-rotor gas turbine and an aerodynamically coupled power turbine. It consists of a sixteen-stage, axial-flow design compressor, an annular combustor with 30 individually replaceable fuel nozzles, a two-stage, high-pressure turbine and a six-stage, high-efficiency power turbine. The gas generator operates at a compression ratio of 18 to 1.
The inlet guide vanes and the first six stages of stator vanes are variable. In both stages of the high-pressure turbine, the nozzles and blades are air-cooled. For industrial applications, the nozzles are coated with CODEP, a nickel aluminide-based coating, and the blades are coated with platinum aluminide to improve resistance to erosion, corrosion and oxidation.
The six-stage power turbine operates at a nominal speed of 3,600 rpm, making it ideal for 60 Hz generating service. Alternatively, it can be used in 50 Hz service without the need to add a speed reduction gear. The LM2500 can also operate efficiently over a cubic load curve for mechanical drive applications.
The 22.0 MWe/31,200 shp LM2500 gas turbine is the most experienced high-efficiency gas turbine in the 20 to 25 MW class. More than 1,700 units are currently in service, which have accumulated more than 33 million operating hours at 98.5 percent documented availability.
The LM2500 gas turbine features:
The aeroderivative LM gas turbine packages are particularly well-suited for marine applications due to their compact size, light weight, low SOx and NOx emissions, high power density and lack of sludge and particulates. The LM2500 has been proven in more than nine million operating hours of marine application.
