The present disclosure relates to combined gas and steam power plants. Various embodiments may include methods for operating such plants, such as: generating hot steam with an exhaust gas of a gas turbine; driving a generator with the steam; diverting at least a part of the generated steam and storing the diverted steam in a steam accumulator; then, discharging at least a part of the steam stored in the steam accumulator from the steam accumulator; heating the steam discharged from the steam accumulator with heat released during an exothermic chemical reaction; and feeding the heated steam to drive the turbine device.

Method for operating a combined gas and steam power plant with steam heated by an exothermic chemical reaction

A power plant having a steam circuit which can be supplied, in the region of a heat recovery steam generator, with thermal energy for producing steam, the steam circuit has, in the region of the heat recovery steam generator, a high pressure part, a medium pressure part and a low pressure part. In addition, a heat reservoir which has a phase change material and which is not situated in the region of the heat recovery steam generator is included, wherein, in order to supply the heat reservoir with thermally processed water, a supply line which leads out from the high pressure part or the medium pressure part is included and a discharge line which leads into the medium pressure part, the low pressure part or a steam turbine is included for discharging thermally processed water from the heat reservoir.
