The need to use only sustainable raw materials and environmentally friendly energy production technologies makes it necessary to look for other ways to reduce pressure on the environment. One method is to reduce the demand for primary energy by increasing the efficiency of the equipment that makes up the energy infrastructure. One of the ways to achieve more favourable operating indicators of thermal equipment and installations in the power and other industries is to improve the technological regime in heat exchange processes by eliminating the build-up of scale deposits in such equipment.The equipment installed in power plants and combined heat and power plants must operate efficiently and with high efficiency. They depend heavily on water quality. Minimal exceedances of the normally permissible indicators can cause the formation of deposits on the walls of pipes and other equipment that impede heat transfer and promote the development of pipe corrosion. Protection against the corrosion
