GE's Uprate Kit Offers Enhanced Power and Efficiency for Original Model LM6000 Gas Turbines
DALLAS, TX - GE Marine & Industrial Engines (M&I) announced an uprate kit for the original LM6000 PA/PB model aeroderivative gas turbine. This kit will offer higher power, lower heat rate and reduced life cycle costs, and will be available starting in February 1998, M&I reported today at Power-Gen International '97.
Through the use of state-of-the-art components, M&I expects performance of an uprated LM6000 PA/PB to match that of the current production LM6000 PC/PD model. An increase at ISO conditions from 42 megawatts to 45 megawatts will be achieved with the uprate.
Initial availability of the kits will be for units with standard combustors. The uprate kits will be available in 1999 for units with M&I's Dry Low Emissions combustion system.
Benefits of the uprate kit include:
- Increased revenue through higher megawatt output;
- Improved power output of 5% to 10% at temperatures above 47oF, and an even higher percent power increase on cold days;
- Enhanced engine heat rate of 3% to 5%; and
- Lowered maintenance costs because of state-of-the-art engine hardware.
The uprate kit hardware improvements, taken from the current production LM6000 PC/PD, include a larger, more rugged and more efficient low pressure turbine (LPT), as well as an improved low pressure compressor (LPC) for increased efficiency.
Since the uprated LM6000 is slightly longer than the current model, a new diffuser, relocation of the rear mounts, and changes to the control system will be required. Other minor changes may be needed depending on the specific package.
The LM6000 uprate kit requires a visit to a service depot to perform the LPT, LPC stator and mid shaft replacement. In the future, M&I expects that upgrades can be performed on site through its component and engine exchange programs.
GE M&I is part of GE Aircraft Engines and is headquartered in Evendale. M&I is the world's largest designer, developer and manufacturer of aeroderivative gas turbines for a variety of power generation, gas compression and commercial and military marine propulsion applications.
