TX-2G Tandem Compound Geared Single Flow

The TX-2G geared turbine consists of two casings and incorporates one high-speed, high-pressure turbine and one intermediate / low-pressure turbine (ILP). A reduction gear between the turbines reduces the rotational speed of the high pressure turbine to 3,000 rpm (50Hz) or 3,600 rpm (60Hz).

The TX-2G turbine system offers benefits not possible with a traditional turbine. One benefit is quick start-up and fast response making the TX-2G a perfect choice to complement variable output of alternative energy sources such as solar energy and wind energy. Additionally, the high speed of the high-pressure turbine reduces the footprint of the TX-2G without sacrificing performance, leading to constructability benefits and construction cost savings.
