<p>A method for operating a combined cycle power plant comprising a gas turbine, a solar field and a high pressure steam turbine, wherein the hot flue gas flowing from the gas turbine enters into a heat recovery unit to heat a molten salt to be used as heat transfer fluid to adjust the flow rate and the temperature of the superheated high pressure steam produced by the solar field depending on the environmental conditions. For conducting such a method, an Integrated Solar Combined Cycle is disclosed, wherein the basic elements are: a gas turbine, a high pressure steam turbine, which is connected to a steam generator, and a solar thermal field, that, together with a steam super heater, is provided between the exit of the gas turbine and the inlet of the steam turbine, wherein the hot flue gases flowing from the gas turbine heat up a molten salt that, as heat transfer fluid, is stored in a first storage tank and used to adjust the temperature of the superheated high pressure steam produced by the solar field and to superheat the steam produced by the steam generator. Furthermore the flue gases coming out from the molten salt heating section are used to preheat the water feeding the solar field and the steam generator.</p> |
