FIELD: water de-aeration equipment, particularly for boiler plants. SUBSTANCE: method of water de-aeration into vacuum de-aerator involves supplying initial water and heating agent into de-aerator; maintaining desired carbon dioxide concentration in de-aerated replenishment water by sequential regulation of heating agent temperature and flow rate, that is preliminary increasing heating agent temperature and then, if necessary, increasing heating agent flow rate when carbon dioxide concentration increases in comparison with desired concentration; primarily decreasing heating agent flow rate and then decreasing heating agent temperature when carbon dioxide concentration decreases in comparison with desired concentration. EFFECT: improved economy and reliability of boiler plant. 1 dwg |
