2  · Relationship between conductivity and steam purity is affected by too many variables to allow its reduction to a simple list of tabulated values. (4) Achievable steam purity depends on many variables, including Evaporator water total alkalinity and specific conductivity as well as design of steam drum internals and operating conditions [Note (3)].

One reason for this is that superheated steam turbines have an extremely low tolerance for solids contamination in the steam. Fortunately, techniques are available to determine steam contamination in

2020-5-7 · 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
