Abstract: Several Northern European countries are facing an incineration plant capacity larger than national generation of waste, mainly caused by a reduced availability of waste, economic crisis and over-investments. This is causing several WTE power plants to operate at reduced or under-utilized waste input capacity. In the aforementioned context, this paper focuses on two 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: additional steam is produced in a simplified Heat Recovery Steam Generator (HRSG) fed by the GT exhaust gas. The proposed repowering options are quite simple and easy to adapt to mid-size under-utilized types of WTE power plant.
