One of the reasons of the degradation of operational efficiency of fossil power plants is corrosion that takes place in the water-steam cycle during operation or downtime. Filming amine octadecylamine (ODA) is one of the chemicals used for reduction of corrosion rate of construction materials during downtime. This chemical not only reduces corrosion rate, but also helps to remove deposits. The data on the ODA effect on the efficiency of removal of deposits from heat exchange surfaces during equipment layup are presented. After ODA application a change in distribution of impurities along the height of deposits was found. In particular, chlorides move from the metal surface to the upper deposit layer, resulting in decrease of the corrosion rate. Results of field tests at co-generation fossil power plant indicate that the use of ODA for the equipment layup reduced tube failures and deposition rate in district water heaters and hot water boilers.
