THERMAL DEAERATOR Russian patent published in 2013 - IPC F22D1/50 

FIELD: power engineering.

SUBSTANCE: thermal deaerator includes a deaeration column installed on a deaerator tank with a low-discharge water-distribution device installed in it - a jet nozzle, arranged in the form of two coaxially installed bodies one inside the other, the external of which has output holes, and the internal one is equipped with a nozzle for water supply and a hole in its lower part, which is below output holes of the external body.

EFFECT: invention makes it possible to eliminate steam ingress into an internal distribution body of a jet nozzle as a result of the fact that a hole in a lower part of an internal body is below output holes of an external body of a nozzle, and thus to provide for reliable operation of a water-distribution device of a deaeration column and a deaerator as a whole with sliding pressure in a wide range of thermal and hydraulic loads.
