| Abstract: | This paper studies a novel quasi-zero CO2 emission IGCC system integrated with Solid Oxide Fuel Cell (SOFC) system. On the base of system integration idea of total energy system, a novel duel-cycle IGCC system integrated with fuel cell combined cycle system and O2/CO2 cycle system has been proposed. The paper analyzes the characteristic of SOFC and optimizes the main parameters of SOFC combined cycle. The system performance of new system has been investigated. The paper also compares the thermal performance of different IGCC systems with CO2 recovery. The promising results show the new system has a higher thermal efficiency after separating and recovering CO2. Compared with the base IGCC system without CO2 recovery, after recovering CO2, the novel IGCC system efficiency does not decrease, but increases by 7 percentage points. Above research achievements will provide the new idea and method for further study on IGCC system with low CO2 emission. |
