发明名称 METHOD FOR VACUUM DEAERATION OF WATER
摘要 FIELD: heat power engineering, applicable at thermal power stations and boiler plants. ^ SUBSTANCE: starting and overheated 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 overheated 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 overheated water heater. At the same time an impulse from the transducer of residual content of carbon dioxide in the deaerated water is applied to the overheated water temperature regulator, and the overheated 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 overheated water is required. ^ EFFECT: enhanced quality and economical efficiency of vacuum deaeration due to overheated water temperature control according to the preset value of the residual content of the discharged gas (oxygen O2 or carbon dioxide CO2). ^ 1 dwg
