摘要
选择陕西紫阳蒿坪镇相同条件地炉 16户 ,其中 8户烧用当地高氟块状石煤、石灰、粘土和低氟无烟煤粉制备的包裹石煤燃料 ,8户燃烧未处理的石煤 ,进行了中试研究 .结果表明 ,包裹石煤组本身煤氟与渣氟比较 ,固氟率平均 75 . 0 % ;室内空气 ,与普通块石煤组比较 ,包裹石煤燃料组氟下降了 85 . 7% ,硫下降 75 . 0 % ,烟尘下降 5 5 . 3% .
The pilot experiment on coated lump stone coal fuel selected from 16 families in Haoping Shanxi were studied. 8 families burned coating high fluorine lump stone coal with lime, clay and low fluorine anthracite, 8 families burned untreated lump stone coal. The results show that the fluorine-fixing ratio at treated group was 75.0% when coal fluorine compared with coal cinder fluorine. In comparison with untreated group, the concentration of door air fluoride lowered 85.7%,SO_2 lowered 75.0%, dust lowered 55.3%.
