VERFAHREN ZUM BETRIEB EINER KRAFTWERKSANLAGE MIT INTEGRIERTER VERGASUNG SOWIE KRAFTWERKSANLAGE

摘要

The method involves gasifying a carbonic fuel by an integrated gasification device (6), and supplying the gasified fuel as synthesis gas to a burner (4) for combustion. Oxygen is separated from air by a membrane (10) e.g. oxygen ion-conducting membrane, at a process temperature such that oxygen-depleted air is formed. Heating energy is supplied to the membrane to maintain required process temperature. The heating energy is partially recovered from the synthesis gas and partially from the oxygen and/or oxygen-depleted air in heat exchange with the air, and the heated air is fed to the membrane. An independent claim is also included for a power plant comprising a gas turbine.
