chemical constitution of coal
The elements or component parts of coal. These are determined by chemical analyses that may be performed in different ways. An ultimate analysis provides exact information as to the percentages of the various elements (such as carbon, oxygen, and hydrogen) present in the coal. Another method is by proximate analysis, which determines the relative percentages of carbon, moisture, volatile matter (such as gas and tar), sulfur, and ash.
