FIELD: heating.
SUBSTANCE: proposed invention serves to produce desalted water and can be used in heat engineering. Proposed system comprises multi-stage instant boil-up evaporator with several expansion stages steam-communicated with evaporator regenerative heaters and at least one expansion stage steam-communicated with heat exchanger. Heat exchanger has cooling water feed and discharge branch pipes, heat circuit warm-up water pipeline, circuit pump and circuit return water pipeline. Heat exchanger feed branch pipe is connected to return water pipeline on the consumer side while discharge branch pipe is connected to suction pipeline of return water circuit pump.
EFFECT: higher efficiency.
