The combustibilityof mixing coal is not equal to the arithmetic plus of each combustibilityof the single blend coal, the former is excelled by the arithmetic plus in some condition.
The char types of the various macerals and their combustion modes were investigated in detail according to the drop tube furnace and one-dimension coalcombustibility tests.
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。

Higher combustibility and coal injection rate can be acquired in BF by using the coal with lower metamorphic degree and higher content of active matter.
