煤是含有无机矿物质的复杂有机物。无机矿物质的成份很复杂,在常规分析中一般是将煤在规定的条件下缓慢灰化后,煤中的一些矿物质转化为各种氧化物。然后测定它们的含量。这就是所谓的煤灰成份分析。根据煤灰成份的测定数据,可以初步判断煤灰的熔融特性;可以大致了解对环境污染的影响;可以制定环境保护的治理措施以及研究综合利用……等。所以煤灰成份分析具有重要的实用价值。在绝大多数煤灰成份中,二氧化硅含 Coal is a complex organic material containing inorganic minerals. The composition of inorganic minerals is very complex. In the conventional analysis, some of the minerals in the coal are converted to various oxides after the coal is slowly ashed under the specified conditions. Then determine their content. This is the so-called coal ash component analysis. According to the determination of coal ash content data, you can initially determine the melting characteristics of coal ash; can be roughly understanding of the impact on environmental pollution; environmental management measures can be developed and the comprehensive utilization of research ... ... and so on. Therefore, the analysis of coal ash has important practical value. Silica is included in most ash components
