METHOD FOR THERMAL DEAERATION OF WATER Russian patent published in 2005 - IPC

FIELD: heat power engineering, applicable at thermal power stations and boiler plants.

SUBSTANCE: heated starting water is fed to the deaerator, deaerated water and flash steam are discharged from the deaerator, and the residual content of oxygen in the deaerated water is measured, an impulse from the oxygen content transducer is transmitted to the starting water temperature regulator, from which in turn, a control signal is transmitted to the actuating mechanism of the regulating member of consumption of the heating medium of the starting water heater. At the same time an impulse from the transducer of the residual content of carbon dioxide in the deaerated water is applied to the starting water temperature control is effected according to the preset value of the residual content of exhausted gas, for attaining of which a higher temperature of the starting water is required.

EFFECT: enhanced quality and economical efficiency of thermal deaeration due to starting water temperature control according to the preset value of the residual content of the discharged gas (oxygen O₂ or carbon dioxide CO₂).
