FIELD: power engineering. ^ SUBSTANCE: method includes heating grid water in grid heaters by steam of heating ducts of thermal turbine, feeding water of heating grid prior to feeding into reverse grid pipeline is deaerated, after that source and overheated water is fed into deaerator. Preservation of given concentration of solved carbon dioxide in deaerated feeding water is performed by consecutive adjustment of source water temperature and steam flow, while in case of increase of concentration of solved carbon dioxide relatively to given value, firstly, temperature of source water is increased, and then if necessary flow of steam is increased, and, vice versa, in case of decrease of concentration of carbon dioxide relatively to given value firstly flow of steam is decreased, and then temperature of source water is lowered. ^ EFFECT: higher efficiency, lower costs. ^ 1 dwg |
