High Capacity Fossil Fuel Fired Plant Operator Training

The steam produced by a boiler is measured in terms of quality which refers to the dryness of the steam. As steam flows, moisture may be carried along or entrained by the steam flow. Pure steam, quality, contains no moisture. So, if the quality of steam is 92%, it contains 8% moisture. Steam that contains any moisture is called wet steam.
