ABSTRACT:
An apparatus for the heating-up and degassing of make-up water by means of steam in a power station plant. The apparatus includes a steam condenser having a casing wall and a second casing wall mounted on the steam condenser. The casing walls are spaced apart and form a mixing chamber and a separation column, with the mixing chamber being located above the separation column. The mixing chamber includes a means for spraying oxygen-rich make-up water. A receiver is positioned to collect water from the separation column and includes a water outlet opening in fluid communication with an interior of the steam condenser. The steam condenser casing wall has a steam-inlet opening located between the receiver and the separation column through which steam flows into and through the separation column and into the mixing chamber due to a lower pressure prevailing in the first stage mixing chamber relative to a pressure in an interior of the condenser. In operation, when the oxygen-rich make-up water is sprayed into the mixing chamber of the apparatus and is brought into contact with the steam introduced through the steam-inlet opening in the steam condenser casing wall, the oxygen-rich make-up water is essentially degassed of most gases by a drop in pressure due to the spraying and an increase in temperature by contact with the steam. Subsequently, the oxygen-rich make-up water enters the separation column located below the mixing chamber where the oxygen-rich make-up water is further degassed and heated up before it is collected in the receiver and fed to the steam condenser.
