What is the Steam Quality of the Boiler？

Steam quality refers to the amount of liquid content in the steam. For example, 100 per cent steam quality refers to the 100 percent of complete steam, without the presence of water in it. In the same way, if the steam quality is 80%, then it will contain 80 per cent of steam and 20 per cent of water. It is very important to detect and identify the percentage of water in the steam as an ample amount of water in steam can adversely erode the piped and valves of the steam boiler. Hence, in any case, if the water is collected in the steam pipes, it would be carried away through high-velocity of steam which may cause inapt vibrations, water hammer and erosion, and may loosen pipe fittings which may further lead to boiler shutdown. Poor steam quality reduces heat transfer efficiency in the operational process and also reduces the lifespan of the internal components of the turbine.
