Standard Test Methods for Determination of Carbon, Hydrogen and Nitrogen in Analysis Samples of Coal and Carbon in Analysis Samples of Coal and Coke

Importancia y uso:

5.1 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.

5.2 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.

5.3 Carbon and nitrogen values can be used in material balance calculations employed for emission accounting purposes.

Note 2: The bulk composition of coal changes at a rate that varies from coal to coal during storage. As a result, using coal for calibration can yield incorrect estimates of carbon, and hydrogen content in particular.
