INTRODUCTION A gas turbine is an internal combustion motive machine. From all points of view, it can be considered as a self-sufficient system: in fact, it is capable to aspirate and compress ambient air via its own compressor, to enrich the energetic power of air in its own combustion chamber and to convert this power into useful mechanical energy during the expanding process that takes place in its own turbine section. The resulting mechanical energy is transmitted via a coupling to a driven operating machine, which produces work useful for the industrial process in which the gas turbine belongs.

HISTORICAL NOTES The first gas turbines to be used in operating applications appeared on the market at the end of the Forties; they were generally used in railways and presented the advantage of burning liquid fuel, even of poor quality. In this regard, we will mention the MS3001 turbine built by General Electric, with a power of 4500 HP, which was used just for this purpose. Successive achievements in material technology and extensive research into combustion resulted in rapid improvements in performance, in terms of specific power and efficiency, obtained by increasing maximum temperatures in the thermodynamic cycle. In this matter, three generations of evolution can be defined, distinguished by the maximum temperature (°C) ranges of gases entering the first rotor stage of the turbine:
