What Is The Dryness Fraction Of Steam In A Package Boiler Without Superheater


Boiler plant and auxiliaries - ScienceDirect

1982-1-1 · The temperature of superheat is the measure of the quantity of moisture originally carried in the steam. The dryness fraction of the steam is expressed by the formula f = (2676 − h) + 1.93 (t − 100) L where f = dryness fraction, h = sensible heat of water corresponding to boiler pressure, t = temperature of steam after the orifice, and L

What is Steam - Properties of Steam - Definition

What is steam. Steam is an invisible gas consisting of vaporized water, which is formed when water boils. When steam is visible, it contains the visible mist of water droplets. Such steam is referred to as "wet steam", but "dry steam" is always invisible.At lower pressures, such as in the upper atmosphere or in the condenser of thermal power plants, steam can exist at a lower
