ABSTRACT:
A water deaeration system has a pump in a supply pipe supplying water to a deaeration vessel. A recirculation pipe interconnecting a heat exchanger between the discharge side and the suction side of the supply pump heats a recirculated portion of the water flowing to the deaeration vessel. A vacuum pump having its suction side connected with the deaeration vessel and its discharge side connected to an air-water separator evacuates the air dissolved in the water and the separator then separates seal water and entrained water from the evacuated air. The vacuum pump has a water seal which is supplied by the separated water in the separator by a seal water pipe connected between the separator and the water seal via the hot side of the recirculation seal water heat exchanger. Heat energy introduced into the seal water by the vacuum pump is transferred to the supply water flowing to the deaeration vessel to be deaerated in order to more efficiently strip the air.
