METHOD OF THERMAL DEAERATION OF WATER Russian patent published in 2004 - IPC

FIELD: heat power engineering.

SUBSTANCE: invention can be used in thermal power stations and boiler plants. According to proposed method of thermal deaeration of water, heated source water and heating agent are supplied to deaerator, and deaerated water and flash steam are let out of deaerator. Flow rate of heating agent is regulated by preset residual content of oxygen in deaerated water. Simultaneously, flow rate of heating agent is regulated by residual content of carbon dioxide in deaerated water, value of flow rate of heating agent being set to provide preset content of most difficult to evacuate gas. Invention makes it possible to improve quality and economy at thermal deaeration owing to control of flow rate of heating agent by preset value of residual content of gas to be evacuated (namely oxygen O₂ or carbon dioxide CO₂) for which greater amount of heating agent delivered into deaerator is required.

EFFECT: improved of deaeration of water.
