GE’s 6B gas turbine fleet has reached 40 years of operation, with the first unit starting up in 1978 and still running. Now, GE has reached its first agreement to repower three 6B gas turbines at a site in Asia.
Europe’s first GE 9EMax gas turbine upgrade has been carried out at an IPP project in the Czech Republic. The upgrade will not only boost plant performance but will also lower running costs and extend plant life.
The 10-year aftermarket for gas turbine-only maintenance has declined from around $239B in 2015 to $200B in 2018, down nearly 16.3% in the last 4 years.
GE has introduced its Cross-Fleet Solutions portfolio – a range of capabilities to service and advance the performance and reliability of other original equipment manufacturers’ gas turbines. The first units to be targeted are the SGT-800 and 501F machines.
The reliable prediction of thermal loads in transition pieces is crucial to increase their life span. Power Systems Mfg. LLC (PSM) discusses best practices in transition piece design to allow aerodynamic pieces that optimize and combine improved cooling effectiveness with low pressure drop and reduced emissions operation.
There are over 1200 LM2500 gas turbines in operation with navies in various parts of the world, and the GE fleet of propulsion gas turbines has proved to be a reliable power provider in these conditions. GTW talks to George Awiszus, Director of Military Marketing for GE Marine, about what is needed for gas turbine propulsion units in naval applications.
Outside of the US, most of industrialized world must import its natural gas as costly LNG and, as they turn away from conventional coal plants and nuclear power, that leaves them with a narrow range of alternatives.
In general terms, 3D printing allows for tremendous benefits to be achieved in terms of speed, cost, and technology, potentially all of these at the same time. Now the process can be used to produce complex 3D-printed metallic components for serial production.
The first GT36 gas turbine – Ansaldo Energia’s advanced H-Class machine – has completed the first phase of a comprehensive validation program. The tests confirm the machine’s high performance and low emissions over the entire load range.
