Used steam turbine FAQ

What types of steam turbines are traded on the used market?

Condensing turbines exhaust into a condenser and turn as much steam energy as possible into power. Back pressure turbines exhaust steam at a pressure that a process can still use, for example in a paper mill, refinery or sugar factory. Extraction turbines take steam out at one or more stages for process heat and send the rest on to the exhaust.

Which manufacturers build the steam turbines sold used?

Units most often traded come from Siemens Energy (SST series), GE Vernova (including former Alstom lines), Mitsubishi Power, Doosan Skoda, MAN Energy Solutions, Elliott, Dresser Rand, Shin Nippon and Triveni.

Which data define a steam turbine for a new site?

Live steam pressure and temperature, steam mass flow, exhaust or back pressure, extraction pressures and flows, output, speed and generator frequency. A used turbine fits a new site only when these values match the boiler or heat recovery steam generator there, so buyers send their steam data first.

Can a steam turbine be added to an existing gas turbine?

Yes. With a heat recovery steam generator behind the gas turbine, the exhaust heat makes steam that drives a steam turbine. This turns a simple cycle plant into a combined cycle plant and produces additional power from the same fuel.

What is a steam turbine generator set?

A package of steam turbine, gearbox where needed, generator, lube oil system and controls on a common base or in a common scope. Buying the complete set saves engineering, because the parts are already matched.

Which documents should a buyer ask for?

Heat balance and design steam data, operating hours and starts, the overhaul and inspection history, rotor and blade 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.

Is a used steam turbine worth it compared with a new one?

A used or surplus turbine is usually available much sooner than a new build and costs less. It is a good choice when its design data fit the site and the documents show a sound maintenance history. A site visit or third party inspection before contract confirms the condition.

How is a used steam turbine bought and paid?

The buyer sends a letter of intent, receives the full data and inspects the unit, then signs the purchase contract with the owner. Payment runs through an escrow agent or an irrevocable letter of credit. LKS 360-SCHREINER LLC never receives purchase payments.
