FIELD: heating. ^ SUBSTANCE: invention refers to heat engineering and is intended for make-up water heating and corrosion-aggressive gases removal from it in water treatment system of nuclear power station. Deaerator includes housing with water and steam inlet connection pipes, vented steam and deaerated water outlet connection pipes, jet and bubble plates located one below the other, confuser arranged in lower part of the housing, vented steam outlet pipeline installed along housing axis and connected to vented steam outlet connection pipe in lower part of the housing. The device also includes a head piece made of concentrically located grids fixed on edges in radial direction with rings-inserts having holes, and the sheet rigidly attaching the head piece to the housing. Holes of upper rings-inserts are equipped with overflow tubes connected to the sheet and forming a distributing chamber between them. Water inlet connection pipe is located on side surface of the housing, and steam inlet connection pipe - in lower part of the housing under the jet plate. ^ EFFECT: providing operating reliability and effective operation of deaerator at increased pressures. ^ 1 dwg |
