SUPERHEATED WATER DEAERATOR Russian patent published in 2012 - IPC C02F1/20 G05D7/00 

FIELD: power engineering.

SUBSTANCE: deaerator comprises a vessel, a pipeline of deaerated water supply, at the outlet of which there is a nozzle of a variable cross section connected to the deaerator vessel, a pipeling of superheated water supply with a conical nozzle, pipelines of deaerated water and vented steam discharge attached to the deaerator vessel. The nozzle of the variable cross section comprises serially arranged confusor, cylindrical and diffusor sections. A conical nozzle of superheated water supply is installed in a confusor section of the nozzle of the variable cross section. The deaerator is equipped with a superheated water flow controller. The superheated water flow controller is connected to a sensor of dissolved oxygen content installed in a pipeline of deaerated water discharge, with a sensor of steam and water flow movement speed, installed in a cylindrical section of the nozzle of the variable cross section, and with a control element installed on the pipeline of superheated water supply.

EFFECT: possibility of automatic control of superheated water flow and content of dissolved oxygen in deaerated water at the outlet of their deaerator, making it possible to efficiently deaerate under different flow rates of deaerated water, which in its turn increases efficiency of deaerator operation.
