In any Power plant running on steam, the purity of boiler feed water and steam is absolutely crucial; especially to steam turbine, steam boiler, superheater, condenser, and other steam equipment. To prevent damage to a steam turbine, steam boiler, and other equipment due to scaling and corrosion, on-line steam and water analysis of critical parameters such as pH, Conductivity, Dissolved Oxygen, Silica, Sodium, Hydrazine and Phosphate, etc is a must. Steam can be as hot as 560°C. Pressures can be as high as 250 bar. To keep the power plant up and running with minimum erosion and corrosion of the steam turbine, steam boiler, and condenser, we have developed a fully integrated Steam and Water Analysis System (SWAS) that provides exact, precise measurements on all these critical parameters. Samples are at high temperature & pressure. Sample conditioning is required to bring down the temperature & pressure at the desired level.
