| Abstract: | Biomass （sawdust） gasification ~,ith air of the atmospheric pressure in the bubbling fluidized bed biomass gasifier was studied. Parameters were analyzed included equivalence ratio O. 13 - 0. 33, temperature of the gasifier bed 760 - 860℃. The results showed that： The main ingredients of gases were H2 ： 6.2% - 14.1%,C0：9.9% - 30.2%, CH4： 1.6% - 11.2%, gas yield wasl.0m3/kg- 1.74m3/kg, low gas heat value was 3526kJ/m3 - 9184kJ/m3 , carbon conversion rate was 52.3% - 82.3%, the gasification efficiency was 38% - 69.1%. |
