Where is the stuffing box located on a steam turbine?

The stuffing box is an important component in a steam turbine, as it is designed to prevent steam from leaking out of the turbine at the point where the rotor and casing meet. In many turbine designs, the stuffing box is positioned on both sides of the wheel to effectively seal the shaft, accommodating for the axial movement of the rotor during operation. This dual positioning helps to ensure that both sides of the rotor are properly sealed, minimizing steam loss and improving efficiency.

Having stuffing boxes on both sides also allows for better containment of the working fluid, which is crucial for maintaining the performance and reliability of the turbine. This design consideration is fundamental in applications where high pressures and temperatures are present, as in steam turbines. Therefore, placing the stuffing box on both sides ensures comprehensive coverage for sealing and contributes to the turbine's overall functionality and safety.
