灰的组成可以根据其化学性质分成酸性和碱性氧化物，L'氧化物包括，碱性，

The composition of ash can be divided into acidic and basic oxides according to their chemical properties, including L'oxides, alkaline, and so on. When the acid content exceeds 80% to 85%, the melting point is usually refractory; conversely, when the content of alkaline metal oxide in the ash increases, the melting point decreases. The melting of the ash depends mainly on its composition. The chemical melting point is higher and the melting point is higher. On the contrary, the melting point of ash is higher. Reduced ash always contains a certain amount of iron in different gas media (oxidizing or reducing), and exists under different valence conditions, iron is trivalent in oxidizing media, and iron is divalent in low reducing gases , Metallic iron is converted into high-metallic iron. The three melting points of the Duke of temperature in the high-temperature medium are the smallest, the highest intermediate and the smallest silicate silicate can produce a lower melting point in the ash. Therefore, in addition to the chemical composition of coal ash, the oxidation-reducibility of the external atmosphere is also an extremely important influencing factor, especially the high content of coal ash, the more significant the impact, some of the The ash melting point difference of coal ash measured in different atmospheres is 300℃.

The composition of ash can be divided into acidic and alkaline oxides according to its chemical properties, including L'oxides, alkaline, etc. When the acidic composition exceeds 80% to 85%, the melting point is usually fire-resistant; The melting of ashes depends largely on its composition. The chemical melting point is higher and the melting point is higher, on the contrary, the melting point of gray is higher. Reducing ash in different gas media (oxidizing or reductive) always contains a certain amount of iron, and in different price conditions, iron in the oxidation medium is three-price, iron in low-reductial gas is dival, metal iron into high metal iron. The temperature duke's three melting points in high-temperature media are minimal, and the highest middle and smallest silicate silicates produce a lower melting point in the ash. Therefore, the melting properties of coal ash in addition to its chemical composition, the external atmosphere of oxidation-tobackness is also a very important factor, especially the high content of coal ash, the more significant the impact, some high iron-bearing coal ash in different atmosphere measured ash melting difference of 300 degrees C. ...

The composition of ash can be divided into acid and alkaline oxides according to its chemical properties. L 'oxides include, alkali, etc. When the acid content is more than 80% to 85%, the melting point is usually fire-resistant; on the contrary, when the basic metal oxide content in ash increases, the melting point will decrease. The melting of ashes depends on their composition. On the contrary, the melting point of ash is higher. Reduce the ash always contains a certain amount of iron in different gas medium (oxidation or reduction), and it exists under different valence conditions. Iron is trivalent in oxidation medium, iron is bivalent in low reduction gas, and iron is converted into high metal iron. The three melting points of the temperature Duke in the high temperature medium are the smallest. The highest intermediate and the smallest silicate silicate can produce a lower melting point in the ash. Therefore, the fusibility of coal ash depends not only on its chemical composition, but also on the oxidation-reduction of the external atmosphere. Especially, the higher the content of coal ash, the more significant the effect is. The difference of fusing point of some coal ash with high iron content measured in different atmosphere is 300 ℃.
