Abstract

An open-cycle gas turbine system comprising a power section (5, 6, 7, 8, 9), a modulation section (1, 2, 3, 4), and a regeneration section (10, 11) for recovering heat from the exhaust gases. The turbines (6, 7) of the power section operate at a substantially constant maximum temperature, also in the regulation mode (partial load), up to the time a burner (3) of the modulation section is switched off. During the continuous modulation of the delivered power, which is mainly performed by modulating the amount of fuel injected into the burner (3), the efficiency constantly remains at high levels. The system can be sized in such a way to attain a maximum of the efficiency in the regulation mode. The system has rapid response times since the power modulation obtained through the variation of the density of the working fluid maintains unaltered the rpm value and the temperature of the power section, until reduced power values are reached.
