Abstract
There are discussed environmental and technological problems, and analyzes the relationship between the formation of elemental and phase composition of deposits, the corrosion of structural elements of equipment with the composition of natural water and methods of its processing in steam boilers of small and medium productivity of some areas of Krasnodar Krai. There were identified the main phases of the deposits, based on diopside, tremolite, wollastonite, hydroxyapatite, calcite, aragonite and magnesite, as well as mixtures of iron oxides in the form of goethite and magnetite. There was defined that the phase composition of the deposits depends on the molar ratio and equilibrium of cationic-anionic composition of natural and treated water. There was showed that with similar water treatment schemes chosen, it is possible to form easily removable deposits (calcium and magnesium carbonates) and practically insoluble (diopside and tremolite), as well as the appearance of deposits caused by various corrosion processes. Therefore, to reduce the environmental burden associated with removal of deposits, it is advisable to optimize the water treatment schemes, taking into account the quantitative and qualitative composition of formed deposits.
