The reason for the high amount of ash in the pure coal is most likely due to the influence of extraneous mineral matter introduced during mining operations where the coal was obtained. The difference in the pure and blended samples is also quite evident from Table 2 as the blends with higher percentages of coal exhibited higher ash contents.
