 Slagging of coal and coal ash addition to direct financial resistance, viscosity and mineral ash content related support, but also has a relationship with the composition of minerals. More coal mineral composition and geological conditions related to mining, but also with some form of age-related coal. As China's western region of Jurassic coal minerals, which often contain large amounts of calcium and iron compounds. When coal combustion, which eventually turned into calcium and iron oxide, thereby reducing coal ash melting properties, so it is easy to make the coal ash slagging. The Permian Shihezi ash, the content is often as high, it is unlikely that coal ash slagging. In short, a different era coal into coal mineral composition vary widely, so the impact on slagging resistance is different. Slagging of coal is mainly affected by the nature and quantity of ash many factors, so even on the same layer of coal, because of its ash content is often changed, so slagging indicators often have large fluctuations. So slagging index often represent only test coal was kind of situation.
