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

Abstract RU 2243165 C1

FIELD: heat-power engineering; boiler houses and thermal power plants.

SUBSTANCE: proposed method includes delivery of internal water and heating agent to vacuum deaerator and discharge of deaerated water from vacuum deaerator; flash steam formed during deaearation is removed by means of mechanical vacuum pump. Control of operation of mechanical vacuum pump is effected through change of rotational speed of its electric motor by preset magnitude of remaining content of oxygen dissolved in deaerated water.

EFFECT: improved quality; enhanced economical efficiency due to maintenance of optimal mode of operation of pump; reduced power requirements.
