Abstract
In a method for operating a gas turbo-generator set (GT), the caloric potential of the exhaust gases (14) from the gas turbo-generator set (GT) is utilized by guiding them through a heat exchanger (5) which is operatively connected to a hot-air turbo-generator set (LT). A compressor (7) associated with this hot-air turbo-generator set (LT) is operated isothermally by means of point-focused or continuous water injection (24), and, after expansion (6) has taken place, the injected water is collected by condensation (19) in a separator (10). A circuit is thus provided, in which the adaptation of assemblies in order to achieve maximized efficiency is avoided.
