Combustion Behavior of Coals in Rotary Kiln and Their ...
In order to clearly reveal coal combustion behaviors and quantitatively evaluate using coal in a rotary kiln, combustion behaviors of four coals (C13, C23, C32, and C6 coals) and their blended coals were investigated. Meanwhile, their interactions and combustion kinetics were analyzed. The results showed that C13 and C23 coals having combustion characteristics of high heating value, suitable ...
Coal pyrolysis in a rotary kiln: Part I. Model of the ...
A mathematical model is presented which describes the pyrolysis of a single grain of coal and is designed to be incorporated into an overall model simulating the rotary kiln coal pyrolysis process. The grain model takes into account the principal physical phenomena occurring during the conversion of coal to coke, namely, heat transfer toward and within the grain, drying of the coal, and the ...
