FIELD: heating.
SUBSTANCE: thermal power station containing turbine with heating steam bleeding connected to top and bottom network heaters connected to the heated medium between the reverse and supply network pipelines, vacuum deaerator with primary water pipeline, in which the primary water heater is connected, accumulating tank connected by the deaerated water pipeline to the vacuum deaerator and by feed water pipeline via the feed pump to the reverse network pipeline upstream the bottom network heater. The deaerated feed water pipeline between the primary water heater and heating network feeding regulator is connected with the drainage pipeline between the vacuum deaerator and accumulating tank of the connecting pipeline in which the regulating device of the flowrate regulator is installed connected with the flow rate transmitter installed in the deaerated feed water pipeline between the heating network feed pump and heating network feed regulator.
EFFECT: invention improves reliability of the heating unit, ensures stable heating of the primary water upstream the vacuum deaerator.
