| Abstract: | For studying the effect of additive on the combustion characteristics of a coal,five metal oxides and salts were chosen as potential additive components, and by employing the cross cut experimental method,their effects on the combustion characteristics of char particles were examined.Based on the analysis of range and variance,the optimum composition of additive was then derived.Further experiments revealed that the additive with composition as proposed by this research could effectively reduce the ignition temperature of the coal and increase its calorific value during combustion.Finally, on the basis of the experiments, the mechanism of the promotion of coal combustion was discussed. |
