THERMAL DEAERATOR (OPTIONS) Russian patent published in 2021 - IPC F22D1/50 

FIELD: heat power engineering.

SUBSTANCE: thermal deaerator (options) is proposed, including a deaeration column mounted on a deaerator tank equipped with a low-pressure water distribution device - a self-regulating jet nozzle. The jet nozzle is made in the form of two cases installed coaxially one inside the other, the outer of which has outlets, the inner case is equipped with a water supply fitting and a hole in its lower part located below outlets of the outer case. A movable spring-loaded hollow cylinder is installed between the outer and inner cases.

EFFECT: claimed technical solution allows, depending on the hydraulic load of the deaerator, to change the location of the hollow spring-loaded cylinder inside the nozzle and, accordingly, the number of holes, through which water flows, resulting in the operation of the nozzle in all the necessary range of hydraulic loads with minimal change in hydraulic resistance and constant quality of water spraying.
