FIELD: energy.SUBSTANCE: invention relates to heat engineering, particularly to thermal deaerators intended for corrosion-aggressive gases removal from feed water, and can be used in heat energy plants and boiler rooms. Disclosed is thermal deaerator, including deaerating column with low-pressure water distribution device installed on deaerating tank - jet nozzle equipped with water supply union and water outlet holes, wherein nozzle upper part is made in form of annular chamber with perforation on its side wall and with additional water supply union installed on it, and circular partition installed concentrically with nozzle and annular chamber inside deaeration column at the bottom.EFFECT: described deaerator makes it possible to condense inside deaeration column maximum amount of steam, excluding the need for external vented steam cooler and thus utilizing heat and vented steam condensate, increase deaerator operation efficiency and reliability.1 cl, 2 dwg |
