Allgemeine Informationen zur GE LM2500 Turbine

General Electric

Die General Electric LM2500 ist eine effiziente Zweiwellen-Einfachkreislauf-Gasturbine. Sie basiert auf den GE-Flugzeugtriebwerken TF39 und CF6-6. Die LM2500 ist die bewährteste hocheffiziente Gasturbine in der Leistungsklasse von 22 bis 33 MW. Aktuell wurden rund 2.100 Einheiten ausgeliefert und sind weltweit im Einsatz. Die Gesamtbetriebsdauer der LM2500-Turbinen beträgt über 75 Millionen Stunden. Die LM2500 ist seit über 40 Jahren eine der meistverkauften Gasturbinen und gilt als zuverlässigster industrieller Gasturbinengenerator ihrer Klasse. Die LM2500-Turbinenfamilie wird kontinuierlich weiterentwickelt, um den Kunden einen Mehrwert zu bieten. Die GE LM2500-Gasturbine ist einfach zu installieren und zu warten und bietet einen hohen thermischen Wirkungsgrad bei geringem Kraftstoff- und Luftverbrauch.

Application

The GE LM2500 family of gas turbines is ideal for onshore and offshore mechanical drive, plant power generation, pipelines, oil and gas platforms, cogeneration and combined cycle applications.

The General Electric LM2500 turbine is also referred to as an offshore turbine. It fully meets current and future regulations for offshore applications, as well as providing superior availability for a variety of military applications including patrol boats, corvettes, frigates, destroyers, landing craft and aircraft carriers.

Features

Efficient solution for oil and gas and industrial needs.
Quick installation and easy maintenance due to minimal size, weight and space required.
Robust construction (over 99%); availability (over 98%).
Proven ability to achieve fast start-up (<10 minutes) and operate in highly cyclic conditions.
Dual fuel solution: distillate and natural gas.
Capable of utilizing crude oil, propane, coke oven gas, ethanol and LNG.
Reduced NOx (<15 ppm) with DLE combustion chamber; steam or water injection systems are also available to limit NOx emissions.

Model LM2500+: more power with the same proven reliability

Another compression stage for an additional 8 MW of simple cycle output.
One-piece “monolithic disk” first stage (vane+disk) for increased durability.
Improved fit for piping, maximum output and combined heat and power generation.

LM2500+G4: the highest efficiency in the LM2500 family

Modified first stage for increased airflow and pressure coefficient..
Improved compressor and turbine section design and materials for greater performance.

GE LM2500 turbine design

The GE LM2500 includes four major components:

A sixteen-stage compressor (18:1 pressure ratio) with seven stages of rotary stator vanes and inlet guide vanes;
fully annular combustion chamber with externally mounted fuel injectors;
a two-stage air-cooled high-pressure turbine, which drives the compressor and an additional gearbox;
a six-stage aerodynamically coupled low-pressure (3600 rpm) power turbine driven by a high-energy flow of generator exhaust gas.

The LM2500 includes a gas generator, power turbine, fuel and oil pump, fuel management system and speed control system, intake and exhaust sections, cleaning system, controls and engine starting and monitoring devices.
