Ultimate Analysis of some Nigerian coal - IJEAS

2020-4-16  Table 1, shows the ultimate and calorific value analysis results of the coal samples. The percentages of the elemental carbon and hydrogen of the coal samples were close to each other, and fell within the ranges of 78.26 – 83.37 % and 5.73 – 6.00 %, respectively. All the coal samples show low sulphur content of less than 1 %.
