| Abstract: | The different ash melt structures are formed due to the different chemical composition and ion potential of elements in ash and slag, which effect the physical-chemical properties of slag in fur- nace. The structure theory of ash melt was analyzed and a new structure index P/M put forward, and the relationship between P/M and viscosity-temperature properties of slag was studied. Based on the structure model of slag, a new model for prediction of viscosity of slag under high temperature was in- troduced. The comparison between the new index P/M and former one used for prediction of slagging propensity were also made. |
