Power generation - Gas turbines
In the development of gas turbines for utility-type power
generation, thermal efficiency remains the primary goal.
For power-generation applications in the process industry,
however, the focus is on maximum reliability and minimum
downtime. Siemens gas turbines deliver just that,
ensuring maximum plant availability and ultimate leverage
from the E-LNG concept.
 SGT5-2000E and
SGT6-2000E: Boasting
a spectacular reliability
of 99.5 percent,
they are the workhorses
in large-scale
industrial power
generation around
the world. |

Siemens’ tested and proven gas turbine SGT5-2000E for
50-Hz systems (163 megawatt (MW) ISO), and SGT6-2000E
for 60-Hz systems are the ideal workhorses for E-LNG
power plants. They complement extended periods between
scheduled maintenance activities requiring a shutdown
with shortest possible service times.
Spectacular fleet reliability
With an installed base of more than 220 units boasting
more than 10 million hours of operation, a spectacular
fleet reliability in excess of 99.5 percent, and up to 48.000
equivalent operating hours (EOH) between major overhauls,
these engines are uniquely qualified for E-LNG powerplant
service. Built-up disk-type rotors with radial Hirth
serrations and a central tie-bolt, cast vanes and blades in the
hot path, and specially selected auxiliary support systems
account for leading-edge reliability. Lowered combustion
temperatures and enhanced hot-gas path components
enable long service intervals, while dedicated service concepts
allow for short service times.
High load gradients
Integrated control systems, a unique rotor design, a fast
inlet guide vane (IGV) control at the gas-turbine compressor
inlet, a steep thermal load gradient and thermal reserves
in the firing temperature result in load gradients of more
than 10 MW per second.

High tolerance to inert and low-BTU gas
Fuel gas of an LNG process plant often has a very high inertgas content. The
selected engines with modified burners have a high tolerance to inert gases —
up to 40 percent nitrogen (N2) — and show stable operation over the entire
range of specified fuels without changing the burner mode. |
