Superheater


We just learned about the steam locomotive Boiler.

Another part of a steam locomotive is the Superheater.

When the water gets heated up by the fire and goes through the fire tube boiler, it gets really hot and leaves the boiler as steam.
To make it even hotter, that hot steam is sent back into some other pipes to get heated even more.
This is called a superheater.

Superheated steam is better because it is more of a dry steam.
The dry steam holds the heat better, and helps the inside of the engine not get wet and rusty.
