Steam Turbines - Anatomy and Applications topics include: Steam turbine working and fire resisting fluids in them, steam turbine cylinders and hydrogen seal rings in turbine generator. Here are some basics of steam turbines: How they work: A heat source heats water to high temperatures until it turns into steam. The steam then passes through the turbine's spinning blades, which expand and cool, converting the steam's potential energy into kinetic energy. The turbine's blades control the steam's speed, direction, and pressure. The main parts of a steam turbine are: The rotor: Carries the... Show more
