HEAT SUPPLY STATION OPERATION METHOD Russian patent published in 2015 - IPC F24D3/00 

FIELD: heating.

SUBSTANCE: cold water from water line under pressure created with a circulating pump having a possibility of provision of a water flow rate gradient in a near-wall area of the pipeline by means of a variable frequency drive is supplied to a water heater, in which heat exchange between cold water from the water line and water from a return pipeline of the heat supply network takes place. Then, the heated water is supplied to a hot water supply pipeline and after that to consumers; according to the proposed invention, cold water from the water line under pressure created with the circulating pump is supplied by means of a variable frequency drive of the circulating pump with water flow pulsation with frequency of 1-2 Hz and amplitude of 0.10-0.12 of nominal flow rate.

EFFECT: preventing formation of mud deposits on inner surfaces of a water heater and pipelines at operation of a heat supply station due to water flow pulsation.
