Assessing the ash composition and properties in mathematical models of CSR and CRI: A review

Quantitative characteristics of the chemical composition ( U b and I b ) and properties (melting point, actual density) of ash used in predicting CSR and CRI for coke are analyzed. It is found that U b and I b are interdependent but are not analogs, since the first includes the ash content of the co...

Description
Summary:Quantitative characteristics of the chemical composition ( U b and I b ) and properties (melting point, actual density) of ash used in predicting CSR and CRI for coke are analyzed. It is found that U b and I b are interdependent but are not analogs, since the first includes the ash content of the coal, whose variation affects the ash composition. Because of the considerable discrepancy in the U b and I b values calculated from the actual density or chemical composition of the ash and used in the prediction of CSR and CRI , there will be a great discrepancy between the actual and predicted values of CSR and CRI (7–11%).
