This paper focuses on repowering options to improve waste conversion efficiency of an existing under-utilized Waste-To-Energy (WTE) power plant with a Gas Turbine (GT). In particular, this study investigates the feasibility of middle pressure repowering strategies utilizing the hot gases leaving the GT. For each investigated repowering option, minimum GT size is identified along with optimum plant match condition in terms of plants capacity. Detailed modifications to the WTE cycle and the resulting enhancement of its performance are presented for both analyzed middle pressure repowering options. The Energetic viability and energetic results of a representative midsize WTE power plant repowered with different GT commercial units are shown and discussed.

Abstract
This paper focuses on repowering options to improve waste conversion efficiency of an existing under-utilized Waste-To-Energy (WTE) power plant with a Gas Turbine (GT). In particular, this study investigates the feasibility of middle pressure repowering strategies utilizing the hot gases leaving the GT. For each investigated repowering option, minimum GT size is identified along with optimum plant match condition in terms of plants capacity. Detailed modifications to the WTE cycle and the resulting enhancement of its performance are presented for both analyzed middle pressure repowering options. The Energetic viability and energetic results of a representative midsize WTE power plant repowered with different GT commercial units are shown and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
