THE REACTION ANALYSIS OF COAL GASIFICATION IN CONSIDERAION OF THE ASH MELTING PROPERTIES

本文研究了煤灰中矿物化合物的共晶和单质二氧化硅的改性。煤灰由一些粘土矿物和单质二氧化硅组成，熔合温度确定为软化点、熔点和倾点。例如：骨灰的软化点在1200 ~ 100‰之间，熔点在1300 ~ 1400‰之间。但是，在煤灰中，没有化学物质或矿物化合物，具有如此低的聚变温度。因此，对煤灰的软化点和熔点进行了调查研究和实验研究。研究结果表明，煤的软化点是单纯二氧化硅的硫化温度，熔点是煤灰中矿物的共晶温度。

The study for the eutectic of the mineral compounds and the modification of the simple simple silica in the coal ashes The coal ashes are consist some clay minerasls and a simple silica, and the fusion temperature are fefined the softening point, the fusion point, and the pour point.For instance, the softening point for the ashes is from 1200 ﾟC to 100ﾟC,and fusion point is from 1300ﾟC to 1400ﾟC .But, in the coal ashes , there are not the chemical, or mineral compounds, that has a such low fusion temperature.So the investigation research and experimental study were being into practice, for the softening point and the fusion point of the coal ashes. The results of the study, we were obtained interesting results that the softening point is the mpdification temperature of the simple silica, and the fusion point is the eutectic temperature of the mineral matters in the coalashes.
