Steam Separator in a Coal-Fired Power Plant

Steam Separator in a Coal-Fired Power Plant

Boiler Steam Generation:

Water is heated to produce steam in the boiler, which may contain 3–5% moisture.

First-Stage Separation:

A cyclonic separator at the boiler outlet removes large droplets, sending drier steam to the superheater.

Superheater and Reheater:

Steam is heated further, but minor condensation may occur; impingement separators remove remaining moisture.

Turbine Inlet:

A vane-type separator at the turbine inlet ensures steam moisture content <0.5%, protecting blades from erosion.

Condensate Recovery:

After the turbine, a mesh separator removes moisture from condensate before it’s recycled to the boiler.
