Abstract:
1. A method for retrofitting a fossil-fueled power station, the power station comprising a multi-housing steam turbine with a carbon dioxide separation device, the method comprising: configuring a suction capability of the steam turbine for an operation of the carbon dioxide separation device to a process steam to be removed, connecting the carbon dioxide separation device via a process steam line to a cold intermediate superheating line feeding back steam from the steam turbine to a steam generator for reheating, wherein a partly-relaxed steam is provided as process steam in the process steam line from the cold intermediate superheating line, and connecting an auxiliary condenser to the process steam line, in parallel to the carbon dioxide separation device, wherein on failure or deliberate switching off of the carbon dioxide separation device surplus process steam is condensed in the auxiliary condenser.
