4.1 Carbon and hydrogen values can be used to determine the amount of oxygen (air) required in combustion processes and for calculation of the efficiency of combustion processes. 4.2 Carbon and hydrogen determinations can be used in calculations including material balance, reactivity and yields of products relevant to coal conversion processes such as gasification and liquefaction. 4.3 Carbon and nitrogen values can be used in material balance calculations employed for emission accounting purposes. 1.1 Test Method A covers the
determination of carbon in the range of 54.9 % to 84.7 %, hydrogen
in the range of 3.25 % to 5.10 %, and nitrogen in the range of
0.57 % to 1.80 % in the analysis samples (7.1) of coal.
1.1.1 Test Method B covers the determination of carbon in analysis samples of coal in the range of 58.0 % to 84.2 %, and carbon in analysis samples of coke in the range of 86.3 % to 95.2 %. 1.2 All percentages are percent mass
fractions unless otherwise noted.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
