Abstract
The invention concerns a turbine arrangement comprising a gas turbine unit with a compressor (), a combustion chamber () and a turbine expander (). The turbine arrangement also has a first unit () for heat exchange and steam generation. This first unit () receives gas from the turbine expander (). The first unit () comprises a first and a second gas flow path which are at least partly separated from each other. A supplementary combustion unit () is arranged to heat the gas in said first gas flow path. Further included is a steam turbine circuit with a steam turbine () which is driven with steam generated with the help of the first unit (). A humidifying device () is arranged to add a liquid to a gas from the compressor () and a first conduit member () conducts humidified gas from the humidifying device () to the combustion chamber (). The first gas conduit member () is arranged such that heating of the humidified gas is done with the first unit (). The invention also concerns a method of operating a gas turbine arrangement.
