【Abstract】 The maceral characters are analyzed for the pulverized coal adopted from power stations. It is found that the maceral analysis has no direct correlations with the proximate and ultimate analysis. The pulverized coal for power generation boilers commonly consists of several pats with different rank. A correlation exists between fuel ratio and vitranite reflectance for single rank coals, but not for non-single rank coals. Large particles contain more high rank coal than small particles.更多还原
