Monitoring of Water and Steam Chemistry for Steam Generators

By Brad Buecker, ChemTreat Inc. |

Online monitoring of steam and water chemistry in a steam system is important for safe and reliable operation of steam generators High-pressure, high-temperature steam is a critical commodity at power plants and at many chemical process industries (CPI) facilities. Examples abound in heavy industry, where co-generation facilities are common. In these plants, a portion of the steam generated is utilized to drive power-generating turbines, while the remainder is used for other turbine applications or for process heating needs. For instance, in the steel-manufacturing industry, steam-driven turbines serve as the prime mover for the air feed to blast furnaces. In facilities where steam is generated, it is not uncommon for the control and monitoring of water and steam chemistry to be neglected because intense attention is focused on process operations. Only when a failure occurs is action taken in the area of water/steam chemistry. In decades past, when conventional coal-fired power generation was the norm, numerous lessons were learned that emphasized the criticality of water- and steam-chemistry monitoring. Many of these lessons were quite dramatic, and, when ignored, underlined the possibility of not only lost production and equipment…
