Method for operating a gas and steam turbine plant and the correspondingly designed gas and steam turbine plant

摘要

The method involves escaping flue gas (R) from a gas turbine that is conducted through a waste gas steam generator (20) and utilizing a flow medium that is used to drive a steam turbine that is conducted in a flow medium circuit (16). The flow medium circuit has multiple pressure stages (92,100). The height of the fluid column is monitored by the flow medium in downpipes (102) that are connected to a steam collection drum (48). An independent claim is included for a gas and steam turbine plant, which has a gas turbine.
