Abstract: The melting characteristic of coal ash is an important indicator of coal's gasification and combustion,melting characteristics of coal are related to not only the chemical composition of the ash but also its composition of the mineral form . Because the melting temperature of coal ash is related to ternary phase equilibrium of all the compositions of coal ash
Ternary equilibrium -phase diagrams are often used to predict and explain the melting temperature of coal ash . The melting characteristics of coal ash can be changed by adding different additives which interact with oxides in the ash to generate substances with high melting temperature or low melting temperature , or adding coal with different ash melting temperature accordingly .It is very significant to study how to change the melting characteristics of coal ash to make it adapt to different way of slagging-off .Keywords: |
