The purpose of this work is the evaluation of the feasibility of an Oxy-Fuel retrofit on a 660 MWe coal-fired boiler in order to obtain CO2-rich flue gases and avoid post combustion CO2 capture technologies. In order to achieve this goal, a GateCycle R simulation model of a typical existing ENEL power station has been developed in detail and tested under normal operating conditions. Then, off-design conditions using pure O2 and CO2-rich flue gas recirculation have been explored. In particular, four plant configurations have been evaluated, both from the performance and plant complexity points of view. Some interesting results have been obtained, especially for what concerns parameters and configuration quantitative influence to the boiler performances.

Abstract
The purpose of this work is the evaluation of the feasibility of an Oxy-Fuel retrofit on a 660 MWe coal-fired boiler in order to obtain CO2-rich flue gases and avoid post combustion CO2 capture technologies. In order to achieve this goal, a GateCycle R simulation model of a typical existing ENEL power station has been developed in detail and tested under normal operating conditions. Then, off-design conditions using pure O2 and CO2-rich flue gas recirculation have been explored. In particular, four plant configurations have been evaluated, both from the performance and plant complexity points of view. Some interesting results have been obtained, especially for what concerns parameters and configuration quantitative influence to the boiler performances.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
