Waste-to-Energy Steam Cycle

Abstract

This chapter focuses on state-of-the-art waste-to-energy (WTE) steam cycle arrangement and possibilities to improve thermodynamic efficiency, upgrading both steam cycle parameters and cycle layout.

Based on a collection of WTE facilities data, a “state-of-the-art” WTE power plant is identified: Typical values of steam cycle pressures and temperatures are discussed with reference to the corrosion problem and characteristic plant size. Starting from the “state-of-the-art” WTE power plant, a sensitivity analysis is carried out to analyze the effects of the most important steam cycle parameters and configuration, improving the thermodynamic efficiency of the WTE facility. An initial assessment of the importance of the main steam cycle parameters must be outlined as a preliminary study in order to understand the possibilities and the benefits of a thermodynamic cycle upgrade for a WTE power plant.
