FIELD: heating.
SUBSTANCE: present invention is meant for dearation and can be used in heat power engineering. The thermal deaerator comprises a dearation column, fitted on a dearating tank, with a low pressure water distribution device - spray nozzle inside the column, provided with a water inlet pipe and water outlet openings. The spray nozzle is in form of a set of coaxially arranged, one on top of the other, alternating cylindrical and conical ring elements.
EFFECT: provision for reliable operation of the water distribution device and the deaerator as a whole, in a wide range of thermal and hydraulic loads and in the presence of sliding pressure in the dearator shell.
