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

FIELD: power industry.

SUBSTANCE: in a heat supply station containing supply and return pipelines of the heat supply station, supply and return pipelines of a heat consumption system, connected as per an independent diagram to pipelines of the heat network through a heat exchanger, a self-excited hydraulic impact generator installed in the return pipeline of the heat network and a pulse fan blower that is connected hydraulically to the return pipeline of the heat network on one side of an elastic diaphragm, and on its other side it is connected in series through inlet and outlet check valves to the supply or return pipelines of the heat consumption system; additionally, there installed is the second heat exchanger, the third check valve, two temperature controls with control elements, three hydraulic accumulators and gate valves. The first and the second heat exchangers are in-parallel connected as to heating medium with their inlets to the supply pipeline of the heat network and with their outlets to the self-excited hydraulic impact generator. As to heated medium, the first and the second heat exchangers are in-series or in-parallel connected between the supply and return pipelines of the heat consumption system. The third check valve, the first hydraulic accumulator and the first temperature control the control element of which is installed in the return pipeline of the heat network are in-series connected to the recirculating pipeline of the heat network, which attaches the outlet of the second heat exchanger as to heating medium and the supply pipeline of the heat network, into which in the heating medium flow direction there installed in the heat exchangers is the second temperature control with a control element in the supply pipeline of the heat consumption system and the second hydraulic accumulator. The third hydraulic accumulator is installed after the check valve of the pulse fan blower outlet; gate valves are installed at inlets and outlets of supply and return pipelines respectively of the heat network and the heat consumption system.

EFFECT: improving energy efficiency of a heat supply station for independent connection of the heat consumption system by implementation and use in it of pulse circulation of heating medium and pulsating circulation of heated medium.
