METHOD OF PREPARATION OF THE MAKE-UP WATER OF THE HEAT-SUPPLY SYSTEM Russian patent published in 2006 - IPC C02F1/20 F01K17/02 

FIELD: heat-and-power engineering; methods of preparation of the make-up water of the heat-supply system.

SUBSTANCE: the invention is pertaining to the field of heat-and-power engineering, in particular, to the methods of preparation of the make-up water of the heat-supply system and may be used at the heat power plants. The method of preparation of the make-up water of the heat-supply system provides, that the make-up water is deaerated in the deaerator, then a part of the deaerated make-up water is after-deoxygenated in the electron-ion-exchanging filter, and the rest amount of the deaerated make-up water is routed through the bypass pipeline avoiding the electron-ion-exchanging filter; after that both these streams of the make-up waters are mixed and fed into the heat-supply system. The amount of the by-passed water avoiding the electron-ion-exchanging filter is regulated according to the preset value of the oxygen share in the make-up water of the heat-supply system. The technical result of the invention is the increased efficiency and quality of the deoxygenated water due to provision of the stable value of a remaining content of the dissolved oxygen in the make-up water of the heat-supply system at the preset level.

EFFECT: the invention ensures the increased efficiency and quality of the deoxygenated water due to keeping the stable value of a remaining content of the dissolved oxygen in the make-up water of the heat-supply system at the preset level.
