Abstract
Economic reasons, leading to the use of coal and the environmental concerns, call for clean technologies for the electric power production. Accordingly the adoption of Integrated Gasification Combined Cycle (IGCC) plants with Carbon Capture and Storage (CCS) have been pushed. Such a technology is promising but it still shows some peculiar aspects. Some of them are related to stable and controllable operations of commercially available Gas Turbines (GTs) designed to be fed with Natural Gas (NG) once the original fuel is replaced by the hydrogen-rich syngas produced in an IGCC-CCS plant. . The thermo-physical properties of the H2-rich syngas require investigations and modifications of the combustor and of the turbomachines to meet stable and safe GT behavior. Such properties strongly affect the matching between GT compressor and expander. . To run the GT with the syngas, various options can be taken into consideration. Some of them do not require GT flow function modifications, while other options involve compressor and expander flow function modifications.. In the present paper some compressor modifications that can be adopted to maintain a F Class GT performance and stability are explored. Such modifications have been analyzed by means of a high fidelity quasi-one dimensional lumped performance tool for the GT sizing and analysis.
