THM1304 Mechanischer Antrieb
Typical applications
Twin shaft gas turbines have a variable speed drive shaft which is the best and most effi cient way not only to control fl ow or discharge pressure, but also to start a mechanical drive train.
Driven units are compressors and pumps for pressure increase and transport of gaseous and liquid media.
Gas turbines of twin shaft design are also used for power generation at fi xed speed. Selection criteria in such cases are e.g. the package design or driver communality in combination with mechanical drive units.
Typical application fi elds are midstream and upstream oil & gas production sites operating mainly in simple cycle mode.
