FIELD: de- aeration of water; boiler plants. SUBSTANCE: proposed vacuum de-aeration plant has vacuum de-aerator with pipe lines for starting water heating agent and de-aerated water, starting water heater connected to starting water pipe line and heating agent heater connected to heating agent pipe line which are connected in their turn with heating medium pipe lines. Proposed unit is provided with dissolved oxygen content regulator for control of content of dissolved oxygen in heat-supply system. This regulator is connected with sensor showing content of dissolved oxygen in de-aerated water and with control members of pipe lines. EFFECT: enhanced reliability and economical efficiency. 1 dwg |
