Abstract
In a process for the recovery of water, which arises from the combustion of a fuel (19), particularly natural gas, in a combined cycle power station (101) including a gas turbine plant (11), a waste heat boiler (33), and a steam turbine (25) arranged in a water/steam circuit with the waste heat boiler (33), and/or which is added in the form of water or steam (36), the water is condensed out from the flue gas (42) arising from the combustion of the fuel (19) and containing water in the form of water vapor after flowing through the waste heat boiler (33), and is separated in liquid form, in particular by expansion in a utilization turbine (20).
