Preliminary experiments of biomass gasification in a self-heated fluidized bed
Gasification characteristics office husk were investigated in a pilot scale self-heated circulating fluidized bed of 200 mm in diameter and 6 meters in height. The experiment results and the differences in the cases of BFB (bubble fluidized bed) and CFB (circulating fluidized bed) gasification are presented and compared. The results show that the calorific value of gas, gasification efficiency and carbon conversion efficiency of CFB gasification are higher than those of BFB gasification. The temperature difference in CFB gasifier is only 40℃ from bottom to top and carbon content in fly ash is less than 16％.The calculated result shows that calorific value of gas can reached 7 MJ/m3 or so when CFB gasifier is scaled up.
CFB BFB calorific value of gas carbon conversion efficiency gasification efficiency.
