Abstract
A process is disclosed for thermally degassing a condensate or feedwater by heating the condensate or feedwater in a feedwater vessel/degassing means, to which preheated condensate is fed and from which feedwater for heating surfaces heated in a heat recovery steam generator is removed. Structurally simple degassing, advantageous in thermal terms, is achieved by virtue of the fact that the condensate is preheated in a first condensate preheater, and that a partial stream of the preheated condensate, which is preheated further in a second condensate preheater, is used to heat the condensate or feedwater in the feedwater vessel/degassing means.
