QUIZ: Boiler Water Treatment Chemical Guidelines — Part II

Steam purity should not be confused with steam quality. Steam quality is a measure of the amount of moisture in the steam. It is expressed as the weight of dry steam in a mixture of steam and water droplets. For example, steam of 99% quality contains 1% liquid water. Carryover is any solid, liquid, or vaporous contaminant that leaves a boiler

28/12/2020 · In boilers, the pressure is typically maintained at around 100 psi (6.9 bars), which reduces the volume of steam in lbs/ft 3 and increases the boiling temperature of water. For example, at atmospheric pressure water boils at 212°F (100°C) and 1 pound of steam occupies 26.8 ft 3, but at 100 psi water boils at 328°F (164°C) and 1 pound of
