US 11,015,490 B2 · Method for operating a combined gas and steam power plant with steam heated by an exothermic chemical reaction

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.
