VACUUM DEAERATION APPARATUS Russian patent published in 2000 - IPC

FIELD: heat engineering. SUBSTANCE: apparatus has vacuum deaerator, pipeline for water to be treated, deaerated water pipeline, vapor pipeline, heating agent-overheated water pipeline, which are connected to vacuum deaerator. Heating agent-overheated water pipeline has overheated water heating unit and heating agent pipeline connected to the latter and provided with regulating device. Apparatus is equipped with overheated water temperature regulator connected to sensor for detecting amount remaining solved oxygen in deaerated water and to regulating device mounted on heating agent pipeline of overheated water heater. Such construction allows high-quality vacuum desorption of oxygen from water to be provided by maintaining optimum temperature of heating agent supplied into deaerator. Apparatus may be used in electric power stations and boiler units. EFFECT: increased efficiency and reduced operating costs. 1 dwg
