METHOD OF WASHING WATER HEATING SYSTEM, EQUIPPED WITH CAPACITY HEATING DEVICES Russian patent published in 2018 - IPC F28G9/00 

FIELD: heating equipment.

SUBSTANCE: invention relates to the field of heat engineering and can be used in the operation of heat exchangers of a water heating system of multi-storey buildings. Essence of the invention lies in the fact that the method of flushing the heating system, carried out without disassembling, includes the supply under pressure of flushing water and compressed air in the line, risers, liner and capacitive heating devices, rinsing water and compressed air are supplied from one side of the radiator, and the contaminated liquid is drained from the opposite side. Instead of a deaf plug of the lower collector of a capacitive heating device, a passage plug is installed along with pipes, a tap and a flexible hose, then the flushing water and compressed air are supplied to the heating system, under the influence of this process, there is an active mixing of the expanding air and water and the separation of contaminants from the internal surfaces of the pipelines and the lower collector of the capacitive heating device, the formation of contaminated suspension, which is removed into the sewer through the hose when the faucet is open, the method consists of cycles, including the steps: filling - draining.

EFFECT: increasing the amount of heat transferred by the heat exchanger to the air washing it, by reducing the thermal resistance of the layer of solid particles deposited in it, and eliminating the transfer of solid particles to other elements of the heating system.
