Steam Quality Controller
What is Steam Quality? The “quality” of the steam refers to the proportion of water being in gaseous phase (steam) and in liquid phase in the steam actually flowing in the pipes. For example, a steam quality of 97% means that 97% of the mass of the steam is in gaseous state and 3% in liquid state. You might think that the steam traps installed along your steam network are taking care of removing that liquid but it is not the case. The liquid affecting the steam quality is in the form of very, very small droplets of water that are floating within the steam and being entrained with it. Bigger droplets (bigger than 1 micron) can be removed using steam separators, steam filters or steam coalescers but the smaller droplets will get through.
