When steam flows out of the steam boiler, it carries along tiny droplets of water which means the steam has a residual moisture content, i.e. a liquid fraction (1 – 3% of the total mass). This residual moisture content can be reduced to roughly 0.5% of the steam quantity when exiting the boiler, by installing steam dryers for example.
