Abstract
An arrangement for controlling the power output of a closed cycle type of thermodynamic system including shaft-coupled compressor and gas turbine components driving a load such as an electrical generator in which the gaseous working medium flows in a closed circulation system that includes a device for imparting heat to the gas and a storage tank for the gas connected in parallel with a section of the gas circulation system. In order to vary the power output, gas from the circulation system in a cold or hot state, respectively, is flowed through the tank for heat exchange with the gas in the tank such that as a result of the corresponding change produced in the density of the gas within the tank, gas is selectively withdrawn from or delivered into the circulation system.
