Abstract:
1. A method for thermally degassing a working fluid of a two-phase working cycle, the method comprising: preheating a condensate mass flow; feeding preheated condensate into feedwater tank/degaser means, extracting a feedwater mass flow from the feedwater tank/degaser means and feeding said feedwater mass flow to heating surfaces located in a heat recovery steam generator; preheating the condensate mass flow in a first condensate preheater; further preheating a condensate flow fraction of the preheated condensate mass flow in a second condensate preheater; feeding residual condensate mass flow into the feedwater tank/degaser means; and introducing the condensate flow fraction into the feedwater tank/degaser means, thus heating the working fluid in the feedwater tank/degaser means with said condensate flow fraction.
