Knowledge
Plain answers to the questions buyers and owners ask about used and surplus gas turbines, steam turbines and generator sets.
Aeroderivative gas turbines are derived from aircraft engines. They are compact, light, start quickly and are often used for peaking, mobile and oil and gas applications, for example the GE LM2500, LM6000 and TM2500. Heavy duty or industrial gas turbines are built for continuous base load operation and long intervals between overhauls, for example the GE Frame 6B, 7EA and 9E or the Siemens SGT5-2000E and Westinghouse 501 and 701 series.
The units most often traded come from GE (GE Vernova), Siemens (Siemens Energy, including former Westinghouse and Alstom lines), Mitsubishi Power, Solar Turbines (Titan, Taurus, Centaur, Mars), Kawasaki, Ansaldo Energia and Baker Hughes (Nuovo Pignone).
Not without changes. Generator frequency follows shaft speed, so a unit built for 50 Hz usually needs a different gearbox or generator, or a design that is specified for both frequencies. Check the generator nameplate data and ask the owner before making an offer.
In simple cycle the gas turbine drives the generator and the exhaust heat leaves through the stack. In combined cycle the exhaust heat goes into a heat recovery steam generator (HRSG), and the steam drives a steam turbine that produces additional power from the same fuel.
DLE (dry low emissions) and DLN (dry low NOx) are combustion systems that reduce nitrogen oxide emissions without injecting water or steam. Whether a unit has DLE or DLN matters when the site has strict emission limits.
Model and output, operating hours and starts since new and since the last overhaul, condition (unused, preserved or running), the completeness of the maintenance records, the scope of supply (generator, controls, auxiliaries, HRSG, spare parts), frequency and fuel options, and the cost and effort of dismantling and transport from its location.
Operating hours and starts, the maintenance and overhaul history, recent borescope or inspection reports, preservation records for stored units, the scope of supply list and generator data. Full documents are normally released after a letter of intent.
A letter of intent is a written statement from the buyer that names the unit, the price offered, the buyer company, the end user and country of installation and the intended payment route. It is the step that releases full data and inspection. See the LOI step in the buyer guide.
Proof of funds is a bank letter confirming that the buyer can pay the purchase price. It is usually requested before contract or inspection, not with the first enquiry.
Through an escrow agent or an irrevocable letter of credit agreed between buyer and owner. LKS 360-SCHREINER LLC never receives purchase payments.
Gas engine generator sets (for example Caterpillar, Wartsila, MTU, MAN or Jenbacher) suit smaller and modular plants and keep high efficiency at part load. Gas turbines suit larger outputs, combined cycle plants and sites that need high power density. The decision depends on output, load profile, fuel, emissions and site.
Used gas turbines are sold by their owners directly, through brokers and through equipment marketplaces. LKS 360-SCHREINER LLC is an independent broker and lists units on behalf of their owners at lks360.com/inventory.html, with model pages for each turbine type.
Collect model, year, hours, condition, scope and your price idea, then offer the unit through one broker with an exclusive mandate or through several channels. LKS 360-SCHREINER LLC offers owners an exclusive sales mandate with one price in the market, screened buyers and no upfront fee: lks360.com/sell.html
