【 摘 要 】

In this paper, thermodynamic analysis of a biomass based advanced power generation system has been performed. The proposed system is a combination of a biomass gasifier with gas cleaning unit, a solid oxide fuel cell module, an indirectly heated air turbine and a supercritical CO2 power cycle with two stage compression and intercooling. Parametric analysis has been carried out to investigate the influences of major plant parameters, such as, the current density of fuel cell and the air turbine pressure ratio, on power output and overall plant efficiency. The results show that the proposed system can yield overall efficiency in the range of 30-55%.
