offshore platforms, gas re-injection, and liquefied natural gas compressors. The LM6000 was GE's
first aeroderivative gas turbine to employ the dry low emission premixed combustion system; this
system can be retrofitted on LM6000s already in operation. Water or steam injection can also be
used to achieve low nitrous oxide emissions.
Design Information
Five-stage low pressure compressor; 14-stage high pressure compressor; pressure ratio 30:1
Annular combustion chamber
Two-stage high pressure turbine; five-stage low pressure turbine
Two-stage power turbine (6,100 RPM)
The gas generator, power turbine, and auxiliary system are mounted on a single base plate
The enclosure is integrated with the base plate, providing maximum accessibility for gas
turbine and auxiliaries maintenance
The standard configuration, excluding the inlet and exhaust ducts, is 31 by 14 by 14 ft (9.3
by 4.2 by 4.4 m) and weighs 31 t
