  • 16.4.5. Modeling Coal Combustion Using the NonPremixed Model

    Modeling Coal Combustion Using the NonPremixed Model If your model involves coal combustion, the fuel and secondary stream compositions can be input in one of several ways. You can use a single mixture fraction (fuel stream) to represent the coal, defining the fuel composition as a mixture of volatiles and char (solid carbon).
