FIELD: chemistry.
SUBSTANCE: water is cleaned from scale deposits in two cone-shaped vessels joined in series. A portion of water heated in boilers is passed through the vessels under pressure of up to 1 MPa with flow rate at which water stays in each cone-shaped vessel for 60±10 minutes. In the first cone-shaped vessel, water is treated with a constant electric field with strength E=2.0±0.5 V/cm and polarity of E changes at a period of almost one hour. Scale deposits accumulating at the bottom of the cone-shaped vessels are periodically discharged through bottom valves. The water is continuously treated from the beginning of the heating season for 1.5-3 months until water in the boilers and heating system is completely clean.
EFFECT: efficient cleaning of water from scale deposits during the entire heating season and cutting heat consumption on heating water.
