Abstract

In the work, on the basis of the data of the analysis of theoretical works and the laboratory studies carried out, the prediction of the values of corrosion rates in the circulating systems of coke plants was carried out using the Langelier and Ryznar stability indixes. The laws governing changes in the thermal stability of water as a function of temperature and water quality indicators (pH, alkalinity, total salinity, calcium ion content) have been established. Analysis of the obtained data showed that there is a clear dependence of the scale-corrosion properties of water on temperature and its chemical composition. A stable and effective supplying water composition for the circulating water supply system of the Kharkiv Coke Plant has been established.
