METHOD OF A VACUUM DEAERATION OF WATER Russian patent published in 2005 - IPC

FIELD: heat power engineering.

SUBSTANCE: the invention is pertaining to the field of heat power engineering and may be used in boiler rooms and the thermal power stations. A method of a vacuum deaeration of water, according to which the initial water and the heating agent are fed into a vacuum deaerator and deaerated water is withdrawn from the vacuum deaerator and the flash steam formed in the process of deaeration is removed with the help of a mechanical vacuum pump. Control over operation of the mechanical vacuum pump is performed by a change of the rate of its electric drive rotation speed according to the given value of pH of the deaerated water. The technical effect achievable by the stated invention consists in upgrading of the quality and efficiency of the vacuum deaeration of water due to maintenance of an optimal mode of operation of the mechanical vacuum pump and due to exception of its operation at excessive power consumptions.

EFFECT: the invention ensures upgrading of the quality and efficiency of the vacuum deaeration of water.
