What type of combustor is used by the GE LM2500 gas turbine engine?
annular
The combustor is an annular type with 30 fuel nozzles and 2 spark ignitors. Of the air from the compressor approximately 30% is mixed with fuel to support combustion.
How does a GE gas turbine work?
In order to generate electricity, the gas turbine heats a mixture of air and fuel at very high temperatures, causing the turbine blades to spin. The spinning turbine drives a generator that converts the energy into electricity.
How efficient are gas turbines?
A simple cycle gas turbine can achieve energy conversion efficiencies ranging between 20 and 35 percent. With the higher temperatures achieved in the Department of Energy’s turbine program, future hydrogen and syngas fired gas turbine combined cycle plants are likely to achieve efficiencies of 60 percent or more.
How much does a gas turbine engine cost?
Roughly speaking, an engine can cost anything from 12 to 35 million dollars. To generate electricity, some powerplants use 100-ton gas turbine engines fuelled by natural gas.
What is a LM2500 gas turbine?
From Wikipedia, the free encyclopedia The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships.
What are the specs of the GE LM2500?
Some other specifications concerning the GE LM2500 include a heat rate of 6,860 shp-hr (shaft horsepower per hour), an exhaust gas temperature of 1,051°F, an exhaust gas flow of 155 pounds per second, a power turbine speed of 3,600 RPMs, weigh about 10,300 pounds, are 6.52 meters in length, and are about 2.04 meters in height.
How much power does a LM2500+G4 generator produce?
When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions. The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions.
What is the LM2500 used for?
The LM2500 is GE’s most widely-applied gas turbine, used by 33 navies worldwide. Possible applications for the LM2500 include patrol boats, corvettes, frigates, destroyers, cruisers, cargo/auxiliary ships and aircraft carriers. The LM2500 is also available as a military generator set.
