Validation of Pure Steam : Pharmaceutical Guidelines

Steam Dryness Value: Dry steam has more energy than the wet steam. Wet steam has water with it and does not have heat energy as dry steam. Dryness of steam is determined by the latent heat. Dryness of the pure steam should not be less than 90%. High moisture content can cause the loss in energy of steam and that may cause the longer

Selection of Blowdown Systems - Industrial steam

Boilers are "blown down" to remove suspended solids and bottom sludge from steam boilers. Removal of suspended solids helps insure the boiler generates high quality steam. It also prevents foaming at the water surface which can lead to unstable water levels and excessive carryover of liquid in the steam.

Applying ASME Boiler Code to Steam Generation Systems

Condensate Water Treatment: Because Steam Boiler Pipes Are

(If you already know, please skip to the next section.) If you have a steam boiler, your boiler system produces steam. Steam leaves the boiler through piping to transfer heat to something; usually a heat exchanger or steam jacket. When the steam condenses in the pipe it is called condensate. This condensate water has very little impurities in it.
