The repowering of existing steam power plants (SPP) by gas turbine (GT) units is studied. The energy integration between the SPP and GT is analyzed taking into account the employment of simple and complex cycle gas turbines. The results reveals the advantages of considering the use of complex cycle gas turbines, especially reheat cycles, for the feed water repowering of steam plant. It is taken into account that these energy advantages are determined by a repowering which, although it is attractive for its simplicity, do not generally allows a better exploitation of the energy system integration in comparison with other repowering solutions. Besides these energy considerations, the analysis on the effects induced by repowering in the working parameters of existing components is also elucidated.

Abstract
The repowering of existing steam power plants (SPP) by gas turbine (GT) units is studied. The energy integration between the SPP and GT is analyzed taking into account the employment of simple and complex cycle gas turbines. The results reveals the advantages of considering the use of complex cycle gas turbines, especially reheat cycles, for the feed water repowering of steam plant. It is taken into account that these energy advantages are determined by a repowering which, although it is attractive for its simplicity, do not generally allows a better exploitation of the energy system integration in comparison with other repowering solutions. Besides these energy considerations, the analysis on the effects induced by repowering in the working parameters of existing components is also elucidated.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
