FIELD: power engineering; water preparation for boiler-houses and small and medium size heat and electric power networks. SUBSTANCE: the invention is dealt with the field of power engineering and is intended for water preparation for boiler-houses and small and medium size heat and electric power networks. Water is frozen at the temperature of minus 2 ...7 = and kept at the indicated temperature for 12 - 24 hours or 36 hours. Then the water is defrosted. Technical effect - expansion of functionalities of the method due to change of parameters of freezing of water (time, temperature), application of softened water in the hot- water boilers, heat points, heaters. EFFECT: expansion of functionalities of the method due to change of parameters of freezing of water, application of softened water in the hot-water equipment and networks. 2 tbl, I dwg |
