Elemental Analysis of Coal Combustion: Coal, Char, and Volatiles

摘要

As the demand for modeling complex processes such as coal combustion in industrial coal applications increases, there is a greater need for sub-models that are both computationally simple and physically detailed. Many research codes rely heavily on simplified chemistry, or do not even include chemistry. The chemistry of the system can greatly affect the performance and accuracy of the simulations. This paper details an analysis of elemental compositions of various aspects of the coal combustion process. Experimental data were analyzed to find a correlation that predicts the elemental compositions of the devolatilization products (char and total volatiles) from the proximate and ultimate analyses of the parent coal. These predictions can inform chemistry and transport models in complex simulations, particularly char and soot reactions.
