GAS TURBINE PLANT WITH IMPROVED FLEXIBILITY

摘要

The invention relates to a gas turbine plant (100) comprising: a gas turbine (1) having a compressor (5), a combustion chamber (6) and an expander (7); and in addition a water-steam circuit (10) which is thermally connected to the gas turbine (1) in such a way that during the operation of said gas turbine (1), the waste gas drawn off therefrom transfers heat to the water-steam circuit (10) in order to generate steam. The water-steam circuit (10) is further thermally connected to a heat accumulator (20) which in turn is thermally connected to a container (30) for storing water. The container (30) is fluidically coupled to the gas turbine (1), in particular to the combustion chamber (6) of the gas turbine (1), in such a way that water can be supplied from the container (30) to the gas turbine (1) during the operation of the latter in order to increase output. A flash valve (50) is connected between the container (30) and the gas turbine (1), said valve being designed to reduce the pressure of the water taken from the container (30) to a lower pressure level.
