METHOD OF VACUUM 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 vacuum deaeration of water, source and superheated water is supplied to deaerator, and deaerated water and flash steam are let out of deaerator. Temperature of superheated water is regulated basing on preset residual oxygen content in deaerated water. Simultaneously, temperature of superheated water is regulated by preset residual content of carbon dioxide in deaerated water, superheated water temperature being set to provide required preset content of most difficult to evacuate gas. Invention makes it possible to improved quality and economy at vacuum deaeration owing to provision of preset content of most difficult to evacuate gas (oxygen O₂ or carbon dioxide CO₂) by changing temperature of superheated water delivered into deaerator.

EFFECT: improved of deaeration of water, reduced energy consumption.
