【 摘 要 】
An experimental study on air gasification of straw was conducted in a tube furnace. The effect of the equivalence ratio (0.1-0.4) and temperature (600-900°C) on various gasification results, including gas composition and vaporized residue was investigated. The equivalence ratio(ER) appeared to have a significant effect on the result of gasification, and the experiment demonstrated the optimal gasification parameters (ER is approximately at 0.2, T is at 800°C). Under this operating condition, the residue after gasification of straw air accounts for about 7.39% of the original straw material, the combustible components in the gasification synthesis gas occupy 71.01% of the total volume, the H2 content is 17.49%, the CO content is 38.02% and the CH4 content is 15.49%. The intersection of the CO and CO2 line charts has realistic implications for the selection of the optimal gas conditions (T, ER) and the increase of gasification efficiency.
