Genloop buys GE Frame 6B gas turbines as principal, running, idle or mothballed, and handles the removal.
The GE Frame 6B, now designated 6B.03, is a heavy-frame gas turbine in service since 1978. Ratings run from about 38 MW on early units to 44 or 45 MW today. The turbine turns at 5,163 rpm and drives its generator through a gearbox, so the same machine serves 50 Hz and 60 Hz grids.
Two 6Bs with the same nameplate and the same total hours can be far apart in price. These are the reasons.
Hours and starts since the last hot gas path inspection and the last major. GE’s baseline for the 6B.03 is 24,000 factored hours or 1,200 factored starts to the hot gas path and 48,000 hours or 2,400 starts to the major. Upgraded hardware stretches those to 32,000 and 64,000 hours.
GE requires a rotor inspection, refurbishment or replacement at 200,000 factored hours or 5,000 factored starts. A unit well inside that is a different asset from one that is near it.
The 6B burns natural gas, distillate, heavy oil, naphtha, and process and steel mill gases. Many ran on whatever the site produced, and a buyer reads the fuel history before the hour meter.
Standard combustors, or dry low NOx as DLN 1 and DLN 1+. A dry low NOx unit can meet a tighter permit. A standard unit needs a retrofit or a site that can permit it.
The 6B has been delivered on every Speedtronic generation from Mark II to Mark VIe. A buyer with an early panel prices in the upgrade.
A 6B moves between grids with a change of gearbox and generator. Genloop will take one across frequencies, with the conversion priced in.
GE counts more than 1,100 Frame 6B units, and the frame is at home wherever a site needs its own power.
Refineries, chemical plants and process sites that need power and steam.
A block of 40 MW suits a system too small for a larger frame.
Blocks that can be on site and running while larger machines are still on order.
Gear-driven, so a unit can be rebuilt for 50 Hz or 60 Hz.
The short answers. The detail is in the contract, and in the call that comes before it.
It depends on where the unit sits in its maintenance cycle, how much rotor life is left, what fuel it burned, its combustion system and controls, and whether it sells as a complete generating set. No public database records what used turbines actually sell for, so advertised prices are asking prices. Genloop makes a firm offer after its own engineers have inspected the unit.
Yes. Genloop buys units that are running, idle or mothballed. A unit that has been mothballed for several years is looked at case by case.
Either. Genloop buys a 6B as a complete generating set, with its gearbox, generator, auxiliary skids, inlet and exhaust, controls and step-up transformer, or with the HRSG as a cogeneration or combined cycle block.
Yes. The 6B turbine turns at 5,163 rpm and drives its generator through a gearbox, and GE applies it in both 50 Hz and 60 Hz markets. Moving one between grids means a different gearbox and generator. Genloop will take a 6B across frequencies, with the conversion priced in.
Fired hours and starts, the dates of the last hot gas path inspection and the last major, rotor hours and starts, the fuels burned, the combustor type, the controls generation, and what is included with the turbine. Gaps are normal and Genloop fills them on site.
Genloop does. Dismantling, export compliance and transport are Genloop’s scope, insured throughout, and written into the same contract as the purchase. The site is handed back on the schedule the contract sets.
No. Genloop buys as principal and takes title, so there is no fee, no marketing period and no waiting for a buyer to appear.
Every enquiry is read by the people who inspect, value and buy the equipment, and answered directly. Owners rarely have everything; send what exists and Genloop fills the gaps on site.
Model and serial number, rating, frequency, and what is included: gearbox, generator, transformer, HRSG, balance of plant.
Fired hours, starts and trips, and the duty the unit ran: base load, cogeneration, peaking, standby.
The last combustion, hot gas path and major inspections, with dates and open findings. Gaps are normal; say where they are.
The fuels burned and for how long, standard or dry low NOx combustors, and the Speedtronic generation.
The window in which the equipment must be gone, crane and road access, and any export or permit requirements.
Who owns the equipment, and what has to be released at closing.
