GE LM2500+ For Sale (31.3 MW, 50 Hz):
GE LM2500+ natural gas-fired and associated Aalborg HRSG. The GE
LM2500+ has a nominal output of 30 MW. The OCGT originally produced
steam for local combined heat and power (CHP”) demand, which no
longer exists. Due to this, the HRSG is kept in dry preservation and
the OCGT operates using the bypass stack, providing black start and
short-term operating reserve capability. Open cycle GE LM2500+ GT
driving a 36 MVA generator, which is a totally enclosed air-cooled
(TEAC”) design rated at 11 kV. The boiler on this unit is currently
in dry preservation.
The LM2500+, a design based on the very successful heritage of the
LM2500 gas turbine, rolled off the production line in December 1996.
The LM2500+ was originally rated at 27.6 MW, for a nominal 37.5
percent thermal efficiency at ISO, no losses and 50 Hz. Since that
time, its rating has continually increased to reach its current level
of 31.3 MW and 41 percent thermal efficiency. The LM2500+ has a
revised and upgraded compressor section with an added zero stage for
increased flow and pressure ratio, and revised materials and design in
the HP and power turbines. The gas generatoroperates at a compression
ratio of 22:1. The inlet end of the LM2500+ design is approximately
330 mm (13 inches) longer than the current LM2500, allowing for
retrofit with only slight inlet plenum modifications. In addition to
the hanging support found on the LM2500, the front frame of the
LM2500+ has beenmodified to provide additional mount link pads on the
side. This allows engine mounting on supports in the base skid.
The CHP plant was a backup steam source from the exhaust gas from a GE
LM2500 installed on site.The Waste Heat Recovery Boiler (WHRB) for the
CHP Plant is capable of generating up to 110 t/h of steam at 21 bar
and 360 °C. In addition, there were additional duct burners in the
WHRB which could augment the steam production. Plant wasused for
backup CHP steam deliver the first few years of operation, backstopped
by a larger combined cycle plant when operational. The contract was
terminated a few years in and the LM2500+ was only used for
black-start and peaking purposes since. Very well maintained directly
by GE for 20+ years until 2020.
Last operational run was in 2020. No recent borescope (2013). Will
sell new parts in storage as well.
Standard LM container is inside another building that has kept it from
external weather conditions.
