显微组分的残炭类型及其燃烧方式

The Char Types of Macerals and Their Combustion Modes

本文依据沉降炉和一维煤粉燃烧特性试验,对不同显微组分的残炭类型及其燃烧方式进行了详尽的探讨。结果表明,薄壁煤胞、厚壁煤胞和网状炭由镜质组形成,在燃烧过程中以等直径方式进行。碎屑炭、结构炭和未熔炭由惰性组演变而来,它们的燃烧服从于等密度方式或混合型方式。

The char types of the various macerals and their combustion modes were investigated in detail according to the drop tube furnace and one-dimension coal combustibility tests. The results indicate that the thin walled cenosphere, thick walled cenosphere and network char are from vitrinite and combustion is conducted in the iso-diameter mode. The micro disrupted char, skeleton char and unfused char are derived from inertinite. Their combustion are submitted to the iso-density mode or the mixed type mode.
