If you have used of any of the larger line boring machines we manufacture, there's a strong possibility that refurbishing steam turbines at power plants is something you've been involved in.
To do this type of work successfully, understanding the principles of steam turbine design is a good place to start. That's why we are sharing the above video created by 'Learn Engineering' which does a great job of explaining how a steam turbine works.
If you've got 5 minutes to watch the video, you'll get a good understanding what's goes on in inside a steam tubine, but if you're pushed for time, a very basic summary is as follows:
- Heat is used to create steam, which enters the turbine
- Like an airplane wing, the profile of the turbine blades creates 'lift'
- The lift rotates the turbine which converts steam flow energy into rotational energy
- As the pressure decreases, more volume is needed, (explaining the 'v' shape to accommodate longer turbine blades)
- In a reaction turbine, fixed blades, called 'stators' increase the velocity of the steam
- The rotation of the turbine shaft is attached to a generator which creates electricity.
- The steam is cooled (e.g. by a cooling tower)
