| 摘 要： | Coal‘s volatile component ,ash and fixed carbon content have different function in different stages of a combustion process,but the traditional coal classification can precisely show its combustion property.In this experiment coal‘s evaluation indeves(ignition index Di),(burn off index Df) were used to qualitatively show the ignition property and combustion ending property of coal samples.Meanwhile,considering actual heating circumstances in calciner(in cement plants),this thesis established the relationship among the ignition index,burn off index and coal‘s industrial analysis value,which makes it possible for the user to predict the quality of coal before using it and is very valuable in practice.

| Abstract: | Coal s volatile component, ash and fixed carbon content have different functions in different stages of a combustion process , but the traditional coal classification can precisely show its combustion property. In this experiment coal' s evaluation indexes ( ignition index Di), ( bum off index Df) were used to qualitatively show the ignition property and combustion ending property of coal samples. Meanwhile, considering actual heating circumstances in calciner ( in cement plants), this thesis established the relationship among the ignition index, burn off index and coal s industrial analysis value,, whifh makes it possible for the user to predict the quality of coal before using it and is very valuable in practice. |
