Frequently Asked Questions
Get answers about Siemens Energy gas turbines.
What is a gas turbine and how does it work?
A gas turbine is a type of combustion engine that converts natural gas or other liquid fuels to mechanical energy. This energy then drives a generator that produces electrical power. The basic process: air is compressed, mixed with fuel and ignited, and the resulting hot gases expand through a turbine to generate power.
What are gas turbines used for?
Gas turbines are used for electricity generation in power plants, mechanical drives for compressors and pumps in oil & gas, combined heat and power (CHP) plants, emergency/peaker power, and marine propulsion.
How efficient are gas turbines?
Simple-cycle gas turbines achieve approximately 35–44% efficiency. In combined cycle configuration, where waste heat is recovered via a heat recovery steam generator (HRSG) to drive a steam turbine, efficiencies exceed 63%, as demonstrated by the Siemens Energy HL-Class.
What are aeroderivative gas turbines?
Aeroderivative gas turbines are derived from aircraft jet engines, adapted for industrial use. They are lighter, more compact, and faster-starting than heavy-duty turbines, making them ideal for decentralized power generation, oil & gas mechanical drives, and applications requiring rapid load response.
What are the main applications of Siemens Energy's gas turbines?
Siemens Energy gas turbines serve oil & gas upstream/midstream/downstream, utility-scale power plants, industrial CHP, district heating, chemical processing, cement and metals, data centers, and marine applications across 60+ countries.
What maintenance and support services does Siemens Energy offer for gas turbines?
Siemens Energy provides comprehensive lifecycle services including long-term service agreements (LTSA), hot-section inspections, combustion inspections, modernization and upgrade packages, remote diagnostics, and 24/7 field service support.
What are the biggest problems with gas turbines?
Key challenges include hot-section degradation, compressor fouling, combustion emissions (NOx), and fuel supply variability. Siemens Energy addresses these through advanced materials, dry low-emission (DLE) combustors, inlet air filtration, and remote condition monitoring.
How do Siemens Energy's gas turbines compare to other manufacturers?
The SGT5-9000HL holds world records for combined cycle efficiency (>63%). The SGT-800 industrial turbine leads its class in power density and availability. With 7,000+ units installed globally and 2,500+ aeroderivative units, Siemens Energy has one of the largest installed fleets of any gas turbine OEM.
