The GE LM2500 is a gas turbine designed and manufactured by General Electric. It is a 6-stage, 50 Hz gas turbine, which is coupled to electrical generators to produce AC current. It used in simple and combined cycle power generation. In a simple cycle power plant, it can deliver an output of 21 and 34 MW. In a combined cycle, however, it can develop a 33-48 MW output.
The GE LM2500 is an aeroderivative turbine, which means it was developed from the CF6 turbine, which is a high-bypass turbofan engine built by GE Aviation. It was first used to power aircraft, but it was later adapted to propel navy ships. However, today it is also employed at power plants world-wide to generate electricity for home and industry. The GE LM2500 turbine is made in two configurations: 1- a gas turbine developed from aircraft engines; 2- gas generator, which can be coupled to an OEM-supplied power turbine.
The latest variant is the LM2500+G4, which is offered by General Electric with two types of power turbines: a) a 6-stage, low-speed model, with an average speed of 3,600 rpm; b) a two-stage, high-speed power turbine, which rotates at 6,100 rpm, with an operating speed range between 3,050 and 6,400 rpm. The latter one is used for mechanical drive and other application.
