This study has considered hybrid system SOFC/GT with the new approach. This cycle; as a power plant is designed to reduce losses and improve comprehensive cycle performance. In the first part cycle; fluidized bed system with biomass (wood chips) fuel using gas cleaning mechanism; produce combustible gases which are required fuel combustion chambers of steam reformer and the GT. Second part cycle; required hydrogen for SOFC system is supplied through external SR. In the third part; the treated bio syn-gas from the cleaning unit outlet; in conjunction with recycled exhaust gases of the cell’s anode will feed SR and GT combustors. In the fourth part cycle; flue gas would pass through heat recovery steam generator. Thus; high pressure and low pressure steams with values 3.39&0.45 ton/hr; respectively are generated. In this study; SOFC and GT with a capacity of 1000 & 750.81 kW respectively are designed. Overall efficiency of power production 74.4% is obtained. In comparison with similar study done in 2008 at the University of Delft; that overall 47% efficiency; increasing the efficiency of such systems has been viewed.
