Abstract
A recuperative air storage plant comprising a gas turbine set and a heat exchanger. In the heat exchanger, exhaust gas heat from the gas turbine set can be transferred to a pressurized stored fluid which flows from a storage volume to a expansion machine. A flow junction with an exhaust gas damper which can be operated in a plurality of positions is arranged in the exhaust gas path of the gas turbine set, upstream of the heat exchanger. This exhaust gas damper makes it possible to divide the exhaust gas mass flow (m) of the gas turbine set in a variable fashion between a stack and the heat exchanger. In this way it is possible to operate the gas turbine set quickly at high power in the electric power network independently of the heat exchanger and the expansion machine, while the thermal load of the air storage part is slowly increased by incrementally increasing the exhaust gas proportion (m) which flows to the heat exchanger.
