This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Oxygen is determined accurately in eight U.S. Bureau of Mines Coal Ash samples A, B, D, F, G, I, and J, N.B.S. Coal Fly Ash 1633 Reference Material, and two Low Temperature Ashes from Illinois State Geological Survey. The method uses fast-neutron activation analysis employing a dual counting and irradiation system which is essentially free of interferences. The stoichiometric balance based on analyses of the ashes performed by the U.S.B.M. is calculated and summations given in oxide and element percent. Excellent agreement is found with the chemical data obtained by classical silicate analysis methods. Accurate oxygen determination for coal ash and LTA ash (or mineral matter) is important for calculation of data in the ultimate analysis of coal as such and is required for recalculation of the data on a ''dry'' and ''dry ash free'' basis. The routinely used ''oxygen by difference'' values are inadequate for accurate work. It is found that the eight coal ash samples analyzed contain 45.5 +- 3% oxygen. Since these ashes represent a large variety of U.S. coals, this figure can be used as an estimate for recalculation and evaluation of the Proximate and Ultimate Coal Analyses.
