Abstract
Apparatus for supplying feedwater to a steam generator, such as a waste-heat boiler, includes the feature of degassing feedwater at a degassing station by way of a suitable degassing means, the feedwater being degassed by being heated to boiling temperature. Prior to reaching the degassing means at the degassing station the feedwater supplied thereto is heated by being placed in a heat-exchanging relationship with respect to water which has already been degassed by the degassing means at the degassing station. The degassed water which is thus cooled by giving up its heat to the water supplied to the degassing means is then delivered to the steam generator at a temperature which is substantially less than the temperature of the water at the degassing means.
