Uryadnikova I. An increase of ecological safety of exploitation of the systems of water preparation and purification in operating in heating power engineering.

Methodology of authentication and classification of risks which arise up in the systems of water preparation and water purification in power engineering on the stage of planning and exploitation is developed. Criticism of the system is offered to estimate on those states in which this system can be. Developed matrix of combinations of elements of the system of water preparation and water purification in power engineering by which expediently to conduct the analysis of risks taking into account probability of refusal of every element. Developed idealised, virtual system of water preparation and water purification, that enables to develop general approaches and scientifically ground them by a probability and mathematical statistics theory. Probabilities of sequence and duration of these events are added to determination, which enables from one side to estimate the risks which arise up during exploitation and to determine management strategy for minimization of these risks. The generalized algorithm of optimum management of the risks at water preparation with the purpose of minimization of risk of exploitation for any system of water purification is developed. The technical and economical analysis of the offered facilities showed the economy of a 1,414 grn/м3 of cleared water.
