摘　　要：对生物质型煤固硫机理进行了理论分析 ,通过实验研究了 Ca/S,固硫剂种类及型煤含硫量对固硫率的影响 .结果表明 ,固硫率随 Ca/S比增大而提高 ,Ca/S=1 .5～ 2范围内 ,固硫率趋于最大值 ,当 Ca/S比大于 2后 ,固硫率随 Ca/S增加的趋势显著变缓 ;在同一 Ca/S比下 ,Ca( OH) 2 的固硫效果最好 ,Ca O次之 ,Ca CO3 的固硫效果最差 ;型煤含硫 3%以下 ,固硫率与含硫量成正比 ,含硫量继续增加 ,固硫趋势不断减缓 .通过对生物质型煤固硫费用的分析 ,得出生物质型煤固硫技术是可行的 .The sulfur retention theory of bio-briquette combustion is analyzed in the paper.The experimental research is carried out on the influence factors of the sulfur retention ratio, with inclusion of Ca/S ratio,sulfur retention additive types and sulfur content of bio-briquette. The results show that the sulfur retention ratio is increased with the addition of Ca/S ratio,the sulfur retention ratio get to the highest in 1.5-2 of Ca/S and the increasing tendency becomes slow;when the Ca/S is the same, the sulfur retention efficiency of Ca(OH) 2 is the best compared of CaO and CaCO 3; when sulfur content of bio-briquette is below 3%, sulfur retention ratio is direct proportion to sulfur content, but the tendency becomes slow with increasing sulfur content. The sulfur retention cost of bio-briquette is also analyzed and the result is that the technology is feasible.
