tandem compound turbine

A tandem compound turbine is a type of steam turbine where the entire machine is assembled along a single shaft connected to one generator. This arrangement is used to manage the significant increase in steam volume as it expands through the turbine. To maintain a consistent steam velocity, the flow area must increase, which can lead to very large turbine diameters and long blades near the exit. In tandem compound turbines, this issue is addressed by splitting the low-pressure steam flow into multiple parallel sections along the same shaft. This design allows for the development of tremendous power within a relatively small space, making steam turbines highly efficient for generating electricity and powering large ships.12
