Differential expansion in a steam turbine happens when the rotor and the casing expand at different rates due to the heat of the steam. This can change the space between them and might cause issues like rubbing, which affects the turbine’s performance.
To avoid problems, it’s important to design and monitor turbines carefully. NCON Turbines is a good option if you need reliable turbines. They focus on creating durable and efficient steam turbines that manage differential expansion well.
