Spraying charged pressured feedwater into the first stage vacuum chamber to initiate the removal of oxygen therefrom and 2. Adjusting the rate of flow of feed water to and through the scheduling means in order to maintain a predetermined volume of partially deoxygenated water at a predetermined level in said first stage vacuum chamber to thereby fluidly seal the first stage vacuum chamber; The first stage vacuum chamber means also including liquid-liquid conduit means interconnecting the partially deoxygenated water in the first stage with the vacuum chamber and means for maintaining a subatmospheric pressure differential so that partially deoxygenated water will flow from the first stage to the vacuum chamber.
