Abstract

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.
