Used Siemens 6.56 MW Steam Turbine Generator Plant, Model EK1000-2, Manufactured 1981. Siemens Model EK1000-2 multistage extraction/condensing steam turbine generator system, rated at 6,560 kW (6.56 MW) shaft output, manufactured in Germany in 1981, Serial No. T5719. Turbine designed for operation at 9,000 RPM with live steam pressure of 48.3 bar (700 PSI) at 404C (759F), intermediate steam extraction pressure of 7.3 bar (106 PSI), and condensing exhaust design pressure of 12 kPa absolute. Equipped with Siemens 6:1 speed reduction gearbox, rated at 6,900 kW continuous duty, reducing turbine speed from 9,000 RPM to 1,500 RPM. Driven generator is a Siemens Model 1DU7534-7FE82-Z three-phase synchronous alternator, Serial No. D8025106101, rated at 8,200 kVA, 11,000 volts, 50 Hz, 1,500 RPM, with 0.8 power factor. System includes associated excitation equipment, electrical control and protection panels, Siemens and GE protection components, SEL digital relays, DECS-250 digital excitation controller, lubrication system with approximately 6,300-liter oil reservoir, and (2) Alfa Laval Model M10-BDFG plate heat exchangers manufactured in 2021. Associated plant equipment includes main steam condenser and steam dump condenser, subject to confirmation of sale scope. Turbine and gearbox underwent extensive major inspection and maintenance in JulyAugust 2023, including rotor removal, internal inspections, non-destructive testing, rotor dynamic balancing, gearbox inspection, bearing inspection, generator electrical testing, and vibration assessment. Inspection records reported acceptable gearbox condition and low post-commissioning vibration levels at that time. Main condenser was retubed in 2012 and inspected in 2023. Originally installed as part of an industrial cogeneration and energy recovery system at a sulphuric acid production facility. Complete engineering documentation, maintenance records, mechanical drawings, electrical schematics, and inspection reports available.
