FIELD: power engineering.
SUBSTANCE: system of recuperation of excessive manifold pressure in heating units of heat supply networks comprises a line of pressure release, comprising parallel connected dynamic pump and stop and control valve with an electric drive, besides, the line of the pressure release is mounted on a return pipeline of the heating point behind a heat-exchange device parallel to an output manifold valve by means of two process valves, the line of pressure release includes a generator of alternating three-phase electric current kinematically connected with the dynamic pump that operates in turbine mode and electrically connected via a commutator with a network of a produced power consumer, and a controller.
EFFECT: invention makes it possible to increase efficiency and reliability of heat supply systems functioning.
