Siemens most popular F class gas turbine is SGT5-4000F, which was entered into market in 1996. Since 1996 total of 360 of SGT5-4000 are being used on the sphere. As per Siemens, it has achieved 23 million EOH (equivalent operating hours) of fleet experience, and achieved 99% of reliability.
SGT5-4000F is at top in its class due to outstanding performance and excellent efficiency (its combined cycle efficiency is reached at about 62%). Maintenance flexibility has results in short outage and thus gas turbine achieved highest availability.
SGT5-4000F gas turbine’s significances are:
- High Fuel Flexibility: offers dual fuel capability and tolerates fuels within a wide Wobbe range
- Proven in commercial operation,
- Efficient: reached to 62% combined cycle efficiency
- Power output augmentation,
- Fast start-up capability: Achieve combined cycle base load in 30 minutes in hot start condition.
- Excellent plant integration,
- High Steam raising capability,
- Evolutionary 3D blading.
