摘要

The method for the output of heat to achieve a high power plant efficiency in a carbon dioxide free power plant in accordance with an oxyfuel process entails using the waste heat of an exhaust gas condenser to first preheat the condensate from the condenser fed by the waste steam (15) from a turbine and then feeding it at a higher temperature to additional heat exchangers. The condensate which has already passed through the exhaust gas condenser (2) is divided into several paths and fed to the heat exchangers (6,10,5,9).
