基于熔体结构的高温灰渣粘度模型

A Viscosity Model of Slag under High Temperature Based on the Melt Structure

从影响结渣物化特性的灰熔体结构入手，针对不同的化学组成以及不同离子在熔体结构中的作用，提出并分析了灰熔体的结构模型以及定量指标Ｐ／Ｍ．研究了灰熔体结构指标Ｐ／Ｍ与灰渣熔体粘温特性的关系，在此基础上，提出了基于熔体结构的高温灰渣粘度模型，并与以往的指标进行了比较．

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.
