摘要(Abstract):

采用透射光显微镜研究了生物质型煤的结构特点,结果表明:随着热解时间增加,单颗粒生物质型煤煤焦的破裂程度加深,生物质型煤煤焦中的孔隙越发达;在相同的热解条件下,秸秆纤维、粘稠液固化物及煤粒交界处更易产生孔隙。生物质型煤中的孔隙越发达,越易形成立体孔隙网,这些孔隙网络有利于氧化剂及反应产物的输送,从而有利于生物质型煤的燃烧和燃尽。
The structure characters of the bio-briquette were studied by transmission electron microscopy in this paper.The results indicate that the fracted degree of single bio-briquette's chars and the amount of holes in the bio-briquette char increased with the prolonging of pyrolysis time;the link place of the stalk fibrin,the condensate liquid and coal grain were easy to product holes.And the holes structure in bio-briquette which formed by molding and pyrolysis is favorable for the combustion and burnout of bio-briquette.
