1-2　エクセルギー再生に基づく高効率バイオマスIGFC発電システムの構築

抄録

In this study, a novel biomass IGFC system with exergy recuperation for power generation was studied by Aspen Plus commercial software. A circulating fluidized bed gasifier system including a f ast pyro ly sis process and a heat-exchangeable-type bio-oil reformer with nickel-based catalyst s was designed. The small amount of char produced from the fast pyroly sis was completely combusted to provide the heat for the pyrolyzer Meanwhile t he large amount of volatile was assigned to two parts, one (69.2%) was reformed to syngas and the other (30.8%) was combusted to supply heat for the catalytic steam reforming process. The generated gas fuel s were converted to electr ic power via SOFC, gas and steam turbine s . The results demonstrate that the exergy efficiency is about 62.91% and the power generation efficiency can reach as hig h as 56. 77 % which was the twice higher than conventional biomass-fueled power plants.
