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。

The test result show that mixed coal injection benefit to raising combustibility, increased quantity and decreased cost.
结果表明，混煤喷吹有利于提高煤粉的燃烧率，扩大高炉喷吹量和降低喷煤成本。

The combustibility of mixing coal is not equal to the arithmetic plus of each combustibility of the single blend coal, the former is excelled by the arithmetic plus in some condition.
