Complex physical and chemical inhibition of corrosion processes and increase the efficiency of heat transfer in the aquatic environment to save energy resources of Ukraine

In order to improve the energy efficiency of heat transfer processes, the processes of scale formation and corrosion on heat transfer surfaces were investigated. An experimental setup and method of deposition of scale in operating conditions, hot water and steam boilers at a temperature of 95 ± 2 ° C, which differ from the known fact, that allow you to monitor and adjust the rate of scale formation, using a constant supply of fresh water to maintain a constant composition of the aquatic environment.
