| 摘 要： | 为了解在1 200 ℃不同反应时间条件下宜阳煤与水稻秸秆混燃的沉积性质,以18 kW的沉降炉为实验平台,利用扫描电镜及能谱,X射线衍射和电子探针方法对混燃的沉积物进行研究。研究表明,不同的混合比例或者不同反应时间条件下,沉积物中的Si、Al和Ca元素变化不大;表面的钾长石的黏性使沉积物更容易富集,而沉积物内部钾长石使沉积物的结构更加稳定;铝硅酸盐和Fe元素在沉积过程中都起了重要的作用。

| Abstract: | Deposition behavior of coal and rice straw co-combustion is studied in different reaction time at 1 200 ℃.The deposition was analyzed by scanning electron microscopy and spectroscopy,X-ray diffraction and electron microprobe in the 18 kW drop tube furnace.The results show that Si,Al and Ca of deposition get a little change in different mixing ratio or different reaction time.The K-feldspar stickability of surface make it easier to deposit,and K-feldspar makes the deposits structure more stable.Aluminum silicate and Fe in the deposition process plays an important role. |
