GEâs Power Services business (GE) is celebrating the 40th anniversary of its 6B gas turbine fleet by launching the worldâs first 6B Repowering Solution. GE also announced it has signed its first agreement for the solution with a global chemical company to repower three 6B gas turbines and save significant amounts of fuel each year at its site in Asia. The announcements mark another example of GEâs continued commitment to investing in its mature fleets to keep them competitive.
Part of GEâs Fleet360 platform of total plant services solution, the new 6B Repowering Solution incorporates advanced F and H class technology to elevate the machineâs performance to leading levels for its class. The repowering consists of a full âflange-to-flangeâ? upgrade of all major components, including the combustion system, hot gas path and compressor, and it transforms the 6B unit into a GE 6F.01 gas turbine, which is also available as a new unit.
The new 6B Repowering upgrade, which fits into the existing 6B footprint, can advance performance in both gas turbine and combined-cycle operation.
It is capable of increasing turbine output up to 35% simple cycle/25% combined cycle, improving efficiency up to 5% points in simple- and combined-cycle operations, achieving up to USD 3M in fuel savings per unit annually and achieving NOx emissions as low as 15 ppm.
Extending the hot gas path inspection interval to 32 000 hours (from 24 000 hours) and major inspection interval to 64 000 hours (from 48 000 hours).
