Used 4.2 MW AEG-Kanis G25 Steam Turbine Generator Set | ABB AMS 710 SL Generator | Back-Pressure Cogeneration System

🏭 Manufacturer Information

• Turbine Manufacturer: AEG-Kanis

• Turbine Model: G25 (Back-pressure steam turbine)

• Turbine Year: 1979

• Generator Manufacturer: ABB

• Generator Model: AMS 710 SL

• Generator Year: 2008

• System Type: Industrial Steam Turbine-Generator Set (Cogeneration / Base-Load Duty)

⚙️ Product Description

This Used 4.2 MW Industrial Steam Turbine-Generator Set is a fully engineered back-pressure cogeneration system suitable for industrial self-generation, process steam utilization, and continuous base-load operation.

The system features a 1979 AEG-Kanis G25 back-pressure steam turbine directly coupled to a 2008 ABB AMS 710 SL synchronous generator. Designed for robust industrial duty, the package includes all major auxiliary systems, ensuring reliable and efficient operation.

The turbine operates at 1500 rpm with superheated steam at ~31 bar (450 psig) and 400–450°C, exhausting into a process steam header. Rated at 4.2 MW mechanical output, it is well suited for facilities requiring both electrical power and thermal energy (CHP).

The ABB generator is rated 4375 kVA, 0.8 PF, 11 kV, 230 A, 50 Hz, and is built for S1 continuous duty. Includes IC 81 W7 air-to-water cooling, IP54 enclosure, and Class F/H insulation, offering long-term durability.

Well maintained in an industrial environment, the package remains serviceable for relocation, recommissioning, or refurbishment.
