It is a derivative of the General Electric CF6 aircraft engine and considered to be one of the most reliable industrial gas turbines ever. These turbines were developed for use on airplanes and became the first gas turbines to be used for the production of electricity. Aircraft engines were initially adapted for stationary power use. The primary role for aeroderivative gas turbines during this early phase was for peaking power.

Actually, they are designed so that fuel and air are mixed and then ignited to achieve the desired output. The resulting flow of hot air is used as the source of powering the turbine. Today, these are typically designed to make use of a combustion process that is continuous as opposed to the intermittent nature of automotive combustion engines. These units have essentially one moving part, however, the complexity is in the high degree of exactness required in the manufacturing and the materials used in their construction.
The hot air that exits the turbine is used for thrust by forcing the air into the atmosphere via an exhaust nozzle. Gas turbines that are not being used in aircraft or other aviation related devices use some of their power to source the compression device. The power that is left goes to drive an energy conversion device, which could be a generator or perhaps a propeller on a vessel. Turbines that are used for generating electrical power can be small enough to be mounted on trucks for mobile implementations or enormous projects that require months to build.
Aeroderivative gas turbines usually weigh considerably less than those designed for land use. These days the aeroderivative models are becoming more popular for use in electrical power applications though more for peak and intermittent purposes rather than base power generation. Advantages of gas turbines The capability of supplying relatively large amounts of power given their size A long life and low maintenance Can be brought online to peak production levels in minutes Can be sourced by a wide range of fuels No coolant is required since air is the working fluid Follow Us:.
Based on advanced aircraft engine technologies and materials, they are significantly lighter, respond faster and have a smaller footprint compared with their heavy industrial GT counterparts. The turbines are also popular due to their fuel flexibility — they allow a combination of natural gas and liquid fuel operation. In the U. Its LMS is a fusion between aero flexibility and heavy-duty power output. The LMS uses an intercooler to cool the air between the low- and high-pressure compressor.
