Study of Possibility of Producing Syngas from Industrial Scale Continuous Downdraft Coffee Husk Gasifier

摘要

This study presents the possibility of producing syngas from the industrial scale continuous downdraft coffee husk gasifier. Experimental results show that, the ratio of main combustible gases obtained in syngas is as follows: CO » 29.07 %, H_(2) » 11.97 %, CH_(4) » 2.16 %. Moreover, the effect of temperature on the ratio of components of syngas was determined. Through the experimental optimization process, optimal technological parameters so that the quality of syngas obtained is best achieved, was determined, specifically: moisture content (10.52 %); wind flow (56.75 m~(3)/h); fuel consumption rate (100.35 kg/h).
